Different Disk settings in a RAID setup??

Hi guys, a quick question, if i setup a striped RAID, using two 1TB Drives, can i :
Partition the drive into 2 partitions(this i think i very possible)
Can i make the partition i want to use as my system disk be journaled, and the other partition normal mac os extended, and will this affect the RAID systems performance???
Cheers

RAID isn't always the answer even for speeding up launching apps and doing normal things. A new drive if you haven't replaced what you have been using for the last two years maybe.
Partitioning can add overhead to seeks and I/O as well. The only good reason would be for static backup archive of files you don't need to access but don't want to "let it go to waste."
The outer 1/3 of a 1TB Black Caviar is the faster section. But then why not get a 640GB and save $$$? and still slice and partition to use just the outer 1/2.
Play with RAID if you are new, but not for system. And audio is better served with discreet drives.
Journaling use to kill performance slightly though I doubt it is a concern, it might. Spotlight is a real killer though and you want to disable it for some volumes.
Having an "OS only" drive makes sense. And use 2nd drive for home folder, media files or something - "two wheel traction and drive."
Want to speed up what the OS does? maybe look toward lower cost and higher capacity SSDs later.
Depending on your current boot drive, and free space and what you store on it, maybe splitting files and upgrading to new drive is what you need. Disk drives have improved a lot since 2007. Even 10K Raptor from 2006/7 isn't a match. Or maybe you would be better served with the new 10K VelociRaptor.
And make drives that are designed to support RAID.
I've used 15K stripe RAID for boot, pair of Raptors, etc and it really isn't always a help. It IS or will be if you are working in CS3+ with 2-3GB files (boot RAID) if you already have the striped scratch, AND the extra memory, and still need something more to work with those large files.
Backups. At least two backups of every drive or volume as a minimum. One off line spare that is off line at any given time, minimum.

W2k8R2 Windows Backup - BMR on different disk configuration - How to move one parition of three parition to an other raid-disk?

Hello folks,
I need your help in following situation.
My source-system has 1 RAID5 (600GB) over 5 HDDs. On the RAID-Disk are one primary partition (250GB) and 1 extended partitions (350GB).
Because the hardware is out of support, I will migrate it to new hardware-server. I must minimized the downtime and the administrative effort. So I can't reinstall a new windows-installation, because 4 different software-licences are binding on SID. Additional
a DFS-R is configured, so I need some hours to reconfigure it.
The new destination-system has one RAID1 (300GB) that I will use it for windows-system, and one RAID 6 (1TB) that is planed for data.
I has make a full backup (with all Critical) by using Windows Server Backup to a NAS storage. Than I has boot my destination system from Windows Server 2008 R2 media, and will make a recover. All Hard Disk is detected, after I install the storage-drivers. When
I confirm the last step in windows-server-backup, windows-backup stop with error "Not enough space on harddisk 0"
How can I move the extended partition to harddisk 1 (RAID6) durring BMR??? I cann't exclude the volume in backup-procedure, because the DFS-R is installed with some share on this disk.
Has anyone a idea?
Best regards

Hi,
I'm afraid we will not get it resolved. BMR will restore the partition information so you need at least a 600GB disk/RAID to restore both Drive C and D - it will create partitions on disk/RAID but cannot be separated restore to different disks/RAIDs.
How about get another 300GB disk and change your system RAID from RAID1 to RAID5. (Or change RAID1 to RAID0 but of course you will lose fault tolerance ability).

Using Disk Utility for RAID setup?

I just purchased 2 1TB Seagate Hard Drives 32mb cache 7200prm that I want to setup a RAID 0 (striping I believe) for Final Cut Pro for rendering. Well I also have a 3rd drive that is identical, question is does more drives in that RAID setup mean faster performance? 2 drives vs 3 or 4, etc.? Also what do you think that actual difference in reading and writing would be approximately?

You can find the max sustained, the average I/O, and minimum. From reviews and Seagate product spec details. There is some overhead for each drive as you seek and assemble the parts of a file.
The burst rate of the drive is likely around 135MB and average of the outer half a solid 100MB/sec.
The bandwidth in the Mac Pro totals 1GB for all drives, even though each is supposed to have 3Gbps.
SSDs are fast catching on for speed and fast system drives, even in stripe raid.
Don't mix 7200.12 with .11s or even different model/series/firmware. And Seagate has had its hands full with firmware issues for years, going back to the intro of SATA actually.
If you want one large volume and if having 200MB/sec matters or helps, you might want to RAID, even partition each drive first to 3/4 level and stripe that 3/4 together to guarantee 200MB/sec range.
But experiment for a couple weeks first.

Pre-Raid Setup Bios Tweaks
Raid Setup On Promise Controller
Raid Setup On Intel Controller
--->Intel- Migrating from single SATA to Full Raid Array
Intro
This guide is intended to help people configure their Bios and setup Windows for Raid using the Intel ICH5R controller and the Promise FastTrak 378 controller. Although all the tests were done using Raid-0 the methods described should be virtually identical to setting up Raid-1 provided the user is aware of the fundamental differences between the two. It should be useful for anyone with an MSI 865PE/875P chipset on motherboards with LSR and FIS2R suffixes. Before continuing, please read the FAQ thread posted by Maesus and the Raid manual(s) that came with your motherboard. There's also some good info regarding Raid Here and Here and Here
Keep in mind this guide is intended as a reference to help you. It is not a manual. I do not work for MSI and my equipment and time are limited. You will have different equipment and different versions of software.
All the data below is based on tests that I ran and I tried to avoid using any theory that I did not test. If you feel I’ve missed something obvious or if you have something you feel should be added to make this guide clearer or simpler, please PM me with your thoughts. If you have a specific problem that this guide does not help you with, post a detailed thread in the forum on the main page.
Equipment List For Tests
MSI 875P FIS2R Motherboard
Bios 1.8
Enermax EG365P-VE (350w) PSU
P4 2.6c CPU
Kingston KHX-3200A2 2x512MB Memory
Radeon 9800Pro AIW Video Card
WD 400JB 40GB/8MB cache IDE Hdd
2-Seagate 80GB 7200.7 SATA Hdd's
Liteon 52x32x52 CDRW
Floppy Drive
Tests
Generally, tests were as follows:
Configure 2 SATA on Promise controller(serial3&4) as Raid0 and install WindowsXP Home SP1a on Raid
Configure 2 SATA on Promise controller(serial3&4) as Raid0 and add Raid to an existing WindowsXP installation on IDE drive(IDE1)
Configure 2 SATA on Intel Raid controller(serial1&2) as Raid0 and install WindowsXP Home SP1a on Raid
Configure 2 SATA on Intel Raid controller(serial1&2) as Raid0 and add Raid to an existing WindowsXP installation on IDE drive(IDE1)
Configure 1 SATA on Intel Raid controller(serial1) and install WindowsXP Home SP1a on it. Then add 2nd SATA on Intel Raid controller(serial2) and migrate to Raid0 using Intel Application Accelerator-Raid edition.
IDE drive used in these tests was pre-installed with a fresh copy of WinXP Home SP1a using default settings and the following drivers all from MSI setup CD and Raid Floppy Disks that came with motherboard:
Intel INF files - version 1002
Gigabit Lan drivers - 7.0.37.0
SoundMax drivers - 5.12.1.3538
Catalyst 3.7 & Multimedia Center drivers from standard ATI CD came with video card.
Pre-Raid BIOS Tweaks
Before I continue, I'd like to point out a few changes from the defaults that I alway make to Bios before I attempt a WinXP install or hardware change. I can't guarantee that they all apply to you but none should make things worse. If anything differs from a setting that you feel is fixing another problem you're having, by all means leave at your prefferred setting. Anything related to performance and overclocking can be raised again AFTER the Raid is all setup and everything is running smoothly.
Standard Cmos Features
The only thing I change here is to enable "32bit transfer mode" whenever I connect new devices to the Intel IDE controller.
Note: Devices attached to the Promise controller and the Intel Raid(when it is enabled) will NOT appear in the standard Cmos page
Advanced Bios Features
Everything on defaults is usually fine except I always change the following for WinXP:
APIC ACPI SCI IRQ - Enabled
Boot Device select is also on this page and you'll be changing it after all the hardware is setup; more later.
Advanced Cipset Features
Confirm that the memory timing "by SPD" is enabled
PNP/PCI Configurations
Clear NVRam option I always set to "YES" before the first boot after making hardware changes. I'm not sure how important this is but I understand that's what you're supposed to do. I believe it forces the motherboard to detect hardware changes. It reverts to "NO" after the reboot.
PCI/IDE Busmaster set to "enabled" to speed things up outside of Windows.
Integrated Peripherals (Before Raid for most flexibilty)
Onboard Promise IDE - Disabled if you have nothing attached to IDE3 and Serial 3&4
ON-Chip IDE Configuration:
Native Mode (Supported by WinXP- Allows all devices connected to IDE 1&2 and Serial 1&2 to be detected)
SATA Only or PATA Only (select the one that you boot XP with)
Keep SATA Active - Yes (if option available)
Keep PATA Active - Yes (if option available)
PATA Channel selection - Both (if option available)
Configure SATA as Raid - No (if option available)
Leave other settings here at default
Note: Some older Bios versions may appear different than above
Frequency/Voltage Control
Dynamic Overclocking - Disabled
Performance Mode - Slow
Dram Frequency - Auto
Adjust CPU Bus - 201 (for "c" type cpu's)
DDR Voltage - 2.65 (minimum for Dual-Channel Mem stability)
AGP Voltage - 1.55
Note: some features above may not appear with your Bios
Note: performance & overclocking features can be increased again AFTER the Raid array has been setup and is stable with Windows.
Raid On Promise Controller
This procedure should work for anyone adding a Raid array to a system already having XP installed on another drive on the Intel controller or intending to install Windows XP on the new Raid array.
Note: IDE 3 and Serial 3&4 connectors are controlled by the Promise controller.
Note: It is possible to setup Raid arrays using 2 IDE drives on IDE3 or even 2 SATA & 2 IDE drives. I only tested 2 SATA drives on Serial 3&4 connectors.
Note: It is possible to setup Raid 0+1 using 2 IDE drives on IDE3 and 2 SATA drives on Serial 3&4. See HERE for a related thread.
Note: It is possible to setup SATA or IDE drives on the Promise controller as separate drives NOT using Raid but I did not test this. See your manual.
- Attach the SATA drives to Serial 3&4 connectors and ensure that both power and data cables are securely connected. Most SATA drives do NOT need any changes to default jumper positions if any(check Hdd installation instructions).
- Boot into Bios
Integrated Peripherals:
Set Onboard Promise IDE - As Raid
- Save and reboot computer
- Use control-F keys during the boot(when prompted-goes by quickly) to enter the Promise Raid Bios.
Note: You will only be able to enter the promise Bios if you have set the Promise controller to "As Raid" AND there are devices connected and detected by the Promise Bios.
- Use the menus to configure the Raid for your preferences.
Note: I can't say which settings you should use for creating the Raid. It depends on many things. Do some research.
- After saving the Raid array, reboot to Bios.(you should see the configured array for a second or two during the post and it should be "functional")
- In Advanced bios Features>>Boot Device Select:
Set the order you prefer to boot from
- If you already have XP installed on another drive and are just adding the Raid for an extra drive, Ensure that the list is still appropriate and includes your XP drive.
- If you will be installing XP on the new Raid, make sure the new Raid array is in the boot list and any other hard drives are NOT.
Note: Typically, I put the disk with XP first and use F11 key during post to boot from another device. This is not required though.
- Save bios
Important!: If you are installing XP on the new Raid array, you should now shutdown and either disconnect or disable any other drives connected until AFTER XP is installed. This includes USB/Zip drives.(See "Bugs" below).
If Installing XP On The New Raid Array(others skip to below):
- Boot from the Windows XP Setup CD and use F6 key when prompted(at the beginning).
- Follow prompts to load the WinXP Promise FastTrack 376/378 Controller from the floppy that came with motherboard(If Required Download Floppy Here). There are a number of different choices on the floppy. PICK THE RIGHT ONE.
Note: if using Win2K with the floppy, you can scroll down to get more driver options on this screen. It's not readily apparent on the screen.
- Continue setup and Windows should now show you the new Raid array as a single drive available to install to. If it shows other drives that you have connected, re-read the "important" note above and the related section on "Bugs" below.
- When XP setup makes its first re-boot, make sure the floppy has been removed or depending on your settings it may give you a scary moment. Yes I did this(tries to boot from floppy).
- After XP is up and running, you can re-connect/re-enable any drives you disconnected earlier. If they have been formatted, they should show up immediately and be assigned letters after your CD/DVD drives.
- You can also install the Promise Array Manager software(from MSI CD utilities tab or download) which adds some array management settings.
If XP Already Installed On Another Drive(and you're just adding the Raid as an extra storage disk):
- Boot into WindowsXP.
- As Windows starts, it should detect a new Raid device and offer to install drivers.
- Select Cancel. It will tell you that it was unable to install new device. If you want you can confirm the new device is present by checking Windows device Manager. It should show the new device with a yellow exclamation mark beside it since the drivers aren't installed yet.
- Download the appropriate drivers or use the MSI CD that came with motherboard.
Note: The MSI CD detects devices connected and shows available drivers/utilities depending on what it sees. You might not have seen the Promise drivers when using the CD before but now that you have a Raid array connected to it, the drivers will be availble from the MSI setup CD.
- Install the drivers and re-boot
- Device Manager should now show the Raid properly identified by XP.
- If the Raid array was not previously formatted, you can now use Windows Disk Manager (Start > Run and type diskmgmt.msc) to Initialize and then format the Raid array.
- The Raid array should now show in Windows Explorer with it's own drive letter.
Bugs/Surprises
- Trying to install WinXP on the Promise Raid while my IDE drive was connected to the Intel IDE connector resulted in Windows installing boot files to the IDE drive and the rest on the Raid drives. This was especially bad since I had another installation of XP on the IDE drive which was overwritten. The work-around was to disable the IDE drive until AFTER XP was setup on the Raid array.
Update: There have been a few posts on the forum since I wrote this guide where people installing XP have had problems similar to the one above with USB/Zip drives connected so i am adding them to the list of drives to disconnect while installing XP.
- When setting "Boot Device Select", if I selected "NO" for "boot from other devices", the motherboard would ignore my selection and still boot from other devices if the ones in the list were unusable.
- Be gentle with SATA connectors on the motherboard. They can stand firm downward pressure but not a lot of side-to-side pressure.
Raid On Intel Controller
This procedure should work for anyone adding 2 SATA hard drives for a Raid array on a system already having XP installed on another drive or intending to install XP on the new Raid array.
Note: IDE 1&2 and Serial 1&2 connectors are controlled by the Intel ICH5R controller. Only Serial 1&2 can be configured for Raid arrays.
You can also install a single SATA drive and configure the system for Raid BEFORE installing XP on this drive if you intend to add another SATA drive later to form a Raid array. This method was also tested. I will refer to this for the rest of the thread as the Raid-Ready Method.
Note: If you install WinXP on a single SATA drive without enabling Raid and loading Raid drivers, you will NOT be able to migrate the XP disk to a Raid array at a later date. Reinstalling XP would be required.
Note: There is no performance advantage to having a single drive with Raid enabled. But doing so makes the disk Raid-ready and XP reinstall unnecessary.
- Attach the SATA drive(s) to Serial 1&2 connectors and ensure that both power and data cables are securely connected. Most SATA drives do NOT need any changes to default jumper positions if any(check Hdd installation instructions).
- Boot into Bios
- In "Integrated Peripherals>>On-Chip IDE Configuration" set:
Native Mode (Supported by WinXP- Allows all devices connected to IDE 1&2 and Serial 1&2 to be detected)
SATA Only (Even if you will be booting XP from a PATA drive)
Keep PATA Active - Yes
PATA Channel selection - Both
Configure SATA as Raid - Yes
Leave other settings here at default
Note: Some older Bios versions may appear different than above.
- Save Bios and reboot computer
- Use control-I keys during post(when prompted-goes by quickly) to enter the Intel Raid Bios Utility.
Note: If you are using the single SATA Raid-Ready Method, you can skip the steps involving the Intel Raid utility. Go to the step for setting Boot device select in main Bios.
Note: You will only be able to enter the Intel Raid Bios if you have set the "Configure SATA as Raid" option to "YES" AND there are devices connected and detected by the Intel Raid Bios.
- Use the menus to configure the Raid for your preferences.
Note: I can't say which settings you should use for creating the Raid. It depends on many things. The Intel utility does describe the different options well though.
- After saving the Raid array, reboot to Bios.(you should see the configured array for a second or two during the post and it should be "functional")
- In Advanced bios Features>>Boot Device Select:
Set the order you prefer to boot from;
If you already have XP installed on another drive and are just adding the Raid for an extra drive, Ensure that the list is still appropriate and includes your XP drive.
If you will be installing XP on the new Raid or using Raid-Ready Method, make sure the new Raid array or raid-ready drive is in the boot list and any other hard drives are NOT.
Note: Typically, I put the disk with XP first and use F11 key during post to boot from another device. This is not required though.
- Save bios
Important!: If you are installing XP on the new Raid array or using the Raid-Ready Method, you should now shutdown and either disconnect or disable any other hard drives connected until AFTER XP is installed. This includes Zip/USB drives. (See "Bugs" below).
If Installing XP On The New Raid Array Or Using Raid-Ready Method(others skip to below):
- Boot from the Windows XP Setup CD and use F6 key when prompted(at the beginning).
- Follow prompts to load the IAA Raid Driver for ICH5R (If Required Download Floppy Here) from the floppy that came with motherboard. I only had 1 driver to choose from on my floppy but if you have more, CHOOSE THE RIGHT ONE!
- Continue and Windows Setup should now show you the new Raid array or Raid Ready drive as a single drive available to install to. If it shows other drives that you have connected, re-read the "important" note above and the related section on "Bugs" below.
- When XP setup makes its first re-boot, make sure the floppy has been removed or depending on your settings it may give you a scary moment. Yes I did this(tries to boot from floppy).
- After XP is up and running and INF files and other important drivers installed, you can re-connect/re-enable any hard drives you disconnected earlier. If they have been formatted, they should show up immediately and be assigned letters after your CD/DVD drives.
- You can also install the Intel IAA-Raid Program(from MSI CD utilities tab or download) which gives some info and adds the array management settings(Not many. Just the enable/disable cache setting and the migrate to raid option).
If XP Already Installed On Another Drive(and you're just adding the Raid as an extra storage disk):
- Boot into WindowsXP.
- As Windows starts, it should detect a new Raid device and offer to install drivers. Select Cancel. It will tell you that it was unable to install new device. If you want you can confirm the new device is present by checking Windows device Manager. It should show the new device with a yellow exclamation mark beside it since the drivers aren't installed yet.

- Install the drivers and re-boot
Note: If the IAA Raid program detects that the Raid controller is not enabled or no device is present, it will NOT allow you to install the drivers/utility.
- Using Windows Device Manager should now show the Raid device properly with no problems.
- If the Raid array has not been formatted, you can now use Windows Disk Manager (Start > Run and type diskmgmt.msc) to Initialize and then format the Raid array.
- The new drive should now appear in Windows Explorer with it's own drive letter.
Bugs/Surprises
- Trying to install WinXP on the Promise Raid while my IDE drive was connected to the Intel IDE connector resulted in Windows installing boot files to the IDE drive and the rest on the Raid drives. This was especially bad since I had another installation of XP on the IDE drive which was overwritten. The work-around was to disable the IDE drive until AFTER XP was setup on the Raid array. It is safe to assume this can occur with the Intel controller as well since I believe the problem occurs because of how WinXP setup addresses the hard drives.
Update: There have been a few posts on the forum since I wrote this guide where people installing XP have had problems similar to the one above with USB/Zip drives connected so i am adding them to the list of drives to disconnect while installing XP.
- Be gentle with SATA connectors on the motherboard. They can stand firm downward pressure but not a lot of side-to-side pressure.
Migrating XP System Disk To Raid On Raid-Ready System
This part describes how to use the Intel Application Accelerator-Raid edition to migrate an existing WinXP system disk (1-SATA) to a 2-SATA Raid array.
This procedure is actually very well documented in the last part of the Intel SATA Raid manual that ships with the motherboard but I thought I’d add it to make this thread more complete.
Please note that to use this feature of the Intel raid software the disk you are migrating FROM must have been made Raid-Ready as described above. Basically, this means that Raid should have been enabled in the Bios and the drivers installed from floppy during the WinXP install.
Note: I tested this by migrating to a Raid0 array but Raid1 should work also if the latest Bios and version of Intel-Raid application used.
- Open the Intel Application Accelerator Raid utility.
- With the “Raid” tab window open, right-click on “Raid volume” and select “Create from Existing Disk” as seen below.
- Follow the next several steps to choose the type of Raid array and the strip size.
Note: 64kb strip size is good for general purpose and 128kb best for most desktops and work stations according to Intel. Anything smaller is for specialized purposes. You should research this a little because you can’t change it after easily.
- After configuring the array for your preferences, you will face a couple of warnings telling you that “All data will be deleted from the Raid-controlled drive(s) and is unrecoverable” and ask if you want to continue. Obviously all data(if any) on the new drive you’re adding will be lost but the OS and other data on the disk you’re migrating FROM will be striped to the new array and will remain intact.
Note: Any complex disk procedure such as this carries the risk of losing data. A backup of the disk is important BEFORE beginning the migration process. Don't say I didn't warn you.
- The migration process can take a long time. You should see the window below during the operation.
Note: With just a default WinXP installation, migrating to 2-80Gb drives took about an hour for me.
- After the migration is complete, you will be prompted to re-boot to complete the process.
- During the reboot, as the Intel Bios comes up for a couple of seconds(don’t blink) you will see the 2 drives configured as an array and they will be listed as “functional”.
- After the reboot, you should have a fully functional Raid array with 2 SATA drives and all data from the single drive will have been striped or mirrored into the second one. Check Windows Disk manager(Start > Run and type diskmgmt.msc) to see the status of the new drive. See bugs/surprises below.
Bugs/Surprises
The only problem I had with this test came in the form of a small surprise after everything was completed and the computer had rebooted. Although the Intel Application Accelerator showed everything functioning normally, Windows explorer showed my Raid drive as 74Gb in size instead of the 150Gb or so that I expected. After checking Windows disk Manager (Start > Run and type diskmgmt.msc), I found that the missing GB’s were in fact there but were unformatted. Unfortunately, Disk Manager does not seem to allow merging or extending partitions so I ended up using Partition Magic 8 to format the empty space and merge it with the rest of the partition. This seemed to work fine and I ended up with a single 150Gb drive showing up in Windows Explorer. I also briefly tested the performance to confirm that it was operating as a Raid array.
I know there is a utility for Win2K called DiskPart.exe that is run from command console to extend NTFS partitions but if anyone knows of an easier way or a FREE utility that will format/merge NTFS partitions that they have confirmed works, please PM me so that I can include a reference to it here.
All the data above is based on tests that I ran and I tried to avoid using any theory that I did not test. If you feel I’ve missed something obvious or if you have something you feel should be added to make this guide clearer or simpler, please PM me with your thoughts. If you have a specific problem that this guide does not help you with, post a detailed thread in the forum on the main page.

Great work vango44!
Here are some RAID performance statistics I gathered while testing RAID on my system. The testing software was Winbench 99. The hard drives tested were new Seagate ST380013AS drives, formatted NTFS. Winbench was running on a third drive that is not included in the tests and should not affect the results.
The drives were reformatted between tests and chkdsk'ed to try and keep things "apples to apples".
No hardware or software changes other than the RAID setup/connections were made between tests.
Higher numbers mean better performance.
I also ran the same tests on the newish WD Raptor 10K drives:
I couldn't stand all the noise the Raptors made, so I returned them.
On my motherboard:
SATA 1 & 2 = Intel RAID controller
SATA 3 & 4 = Promise RAID controller
If the test title does not include "RAID", then it was a single drive test.
Unfortunately, I don't have a spreadsheet version of the above stats. Otherwise I'd create nice bar charts for us and it's would be easier to deduce performance.
Perhaps some kind reader will OCR the pictures, put them into Excel, and make some nice bar charts for us?
Hope the info helps.

Udev/dmraid not picking up all partitions of a fake RAID setup! [EDIT]

Hey all. I've been having a problem with my RAID setup in Arch. At first Arch wasn't picking up a partition on one of my arrays, (a single large NTFS partition on a 2TB array between two 1TB drives) but after re-creating the RAID array in the Intel Storage Manager I have a different problem. Arch now find the single large partition, but now /dev/mapper isn't populated with the other two partitions on the other array that my operating systems are on (Arch and Windows), when it used to just fine! The only thing I changed was re-creating the partition table on the other array, so I don't know what's going on.
Upon trying to boot, GRUB comes back with the error described on the wiki: https://wiki.archlinux.org/index.php/In … oot_device
However I can't boot into the fallback image either! This means that I can't apply the fix as described in the wiki.
I'm starting to think there is a limitation in Arch where it can only handle a certain number of mapper devices (seems to be 3), or maybe it only detects the partitions on the first detected array? Now that I recreated the partition table on the larger array, it seems like that's the array that's detected first in both a GParted live session and Arch. But in a live GParted session, /dev/mapper was fully populated with all of my disks and partitions... so why is it that Arch can only find the partitions on one of the RAID arrays?
If you guys need any additional information just let me know... I really want to get my Arch setup up and working so I don't have to use Windows all that often (only games that don't work well in Wine).
EDIT: Changed post and title to reflect new problem after recreating the 2TB array

Does anyone know if I can damage my arch install by using mkinitcpio through a Debian live-cd? I'm going to try and use one to remake my initrd by chrooting using this guide: https://wiki.archlinux.org/index.php/In … oot_device
Basically the commands I'm looking to execute would be this:
# mount /dev/mapper/isw_ArchRaidPartition /mnt/
# mount -o bind /dev /mnt/dev
# mount -t proc none /mnt/proc
# mount -t sysfs none /mnt/sys
# chroot /mnt /bin/bash
(edit mkinitcpio.conf according to wiki, inserting the "sleep" hook)
# mkinitcpio -p 3.0-arch
So my question is would using the commands from a debian live distro work? I have to use debain since arch live-installs don't detect my arch raid partition, like how I described above. I also can't boot into fallback.

However I can't boot into the fallback image either! This means that I can't apply the fix as described in the wiki.
I'm starting to think there is a limitation in Arch where it can only handle a certain number of mapper devices (seems to be 3), or maybe it only detects the partitions on the first detected array? Now that I recreated the partition table on the larger array, it seems like that's the array that's detected first in both a GParted live session and Arch. But in a live GParted session, /dev/mapper was fully populated with all of my disks and partitions... so why is it that Arch can only find the partitions on one of the RAID arrays?
If you guys need any additional information just let me know... I really want to get my Arch setup up and working so I don't have to use Windows all that often (only games that don't work well in Wine).

Please do not crosspost. Follow forum rules.

Unable to create partition after RAID setup failure

SL - Tried to create RAID 1 with two external 250G drives. The RAID setup failed indicating improper format pair. So....I attempted to re-create the partition on one of the drives with proper settings.
It will not partition at all. It returns a POSIX error: unable to allocate memory.
I've tried the following:
Using startup disk
Partitioning using WindowsXP (which worked....only for Windows)
Tried erasing
Tried to partition with each partition type.
Nothing works! However, when I restart SL, it pops open a window indicating the drive needs to be 'initialized'. I click 'initialize' button, but that doesn't help.

Do the following:
Extended Hard Drive Preparation
1. Open Disk Utility in your Utilities folder. If you need to reformat your startup volume, then you must boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger or Leopard.)
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (for Intel Macs) or APM (for PPC Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
Are you trying to create a RAID using partitions on hard drives or using the entire drive?

Disk on MSI mobo RAID controller to another MSI mobo

Hello,
I'm running two drives in a non-raid setup but they are connected to the RAID controller on the K7N-Delta ILSR motherboard. What I was wondering is wheter I can reconnect these drives directly on the regular controllers without hitches. And can I expect these disks to work properly if i buy a new motherboard and connect them to the RAID controller on the new motherboard which has possibly a diffrent raid controller integrated.

Hello! If the RAID controller is different you might have a problem with a new mobo.
Is there anything obstructing you from saving the data somewhere else, when fixing the setup that you want? 'Thinking it could be a work-around to store selfcreated, important data and stuff on a regular cheapo IDE disk for a while. Updates and programs is not too hard to find, so there is no absolute need to copy and store those.

Pros and cons to JBOD/N-RAID setup on MacBook Pro with two internal SSDs

First, to clarify, in this case, I mean the term "JBOD/N-RAID" to refer to a concatenated or spanning set of drives as supported by OS X and Disk Utility.
I've got an original Apple-installed 120GB 3G (3Gb/s) SSD which I'll be moving into the optical bay using an OWC "Data Doubler" and swapping a new 240GB OWC Mercury Electra 6G (6Gb/s) SSD into the main drive bay.
My goal is to avoid having two separate volumes.
Understand that a RAID 0 array would essentially only perform as well as the slowest drive in the array (the 3G SSD in this case), if it would even work at all given the two drives are not identical in make and capacity.
I've read that a JBOD/N-RAID array isn't subject to the "same make and capacity" constraints. But how does this setup perform?
Would the speed of the 6G be hobbled, slowed down to the 3G's speed (or worse?), if I were to set up the two SSDs as a JBOD/N-RAID array?
Is this even a recommended idea - that is, paying for the convenience of having one virtual volume by adding the complexity (and risks?) of a JBOD / N-RAID setup?

I am following your advice and attempting to install Bonjour. I wasn't sure where to install it so I am following the VMWare Knowledge Base #1003814: Sharing a printer with a Windows virtual machine using Apple Bonjour.
I have copied it below to refer to because I've run into a problem.
I have completed steps 1 a-d.
The Problem: Step 1 e. Click Printers. Printers is not shown under Removable Devices. When I try to Add Device (Printers) it says "New Devices cannot be added until the Virtual Machine is Shut Down and then Resumed." I have shut down the Virtual Machine alone, I've shut down AMware Fusion and I've shut down both Windows and Mac. Nothing has changed when I try and add Printers so I can do Step e.
I sure hope someone can help.
To configure a printer connected to your Mac for use with the Bonjour utility and a virtual machine in Fusion:
Configure your virtual machine for Bridged Networking and disable ThinPrint:
Click Virtual Machine > Settings.
Click Network (Adapter).
Enable Bridged Mode. In Fusion 5.x, select Autodetect under Bridge networking.
Click Show All.
Click Printers.
Set printer sharing to Off.
Click Close.
Reboot the virtual machine.
Install Bonjour for Windows. Download and install Bonjour for Windows in the virtual machine. Bonjour is available from Apple at http://support.apple.com/kb/DL999.
Note: The preceding link was correct as of January 20, 2010. If you find the link is broken, provide feedback and a VMware employee will update the link.
Share the printer in Mac OS:
Open System Preferences.
Click Print and Fax.
Select the printer you want to share, and select Share this printer.
To configure the printer in the guest operating system with the Bonjour Utility:
Double-click the Bonjour Printer Wizard.
Click Next.
Under Shared printers select the printer you want to use.
Click Next.
Click Finish.

MSI 875P NEO-FIS2R RAID SETUP PROBLEM

hie everyone
with my hard disk now , how can i setup raid ?
detail plsee

Your signature shows 3 drives, all different sizes. If you are going to raid a pair, they should preferrably be the same size and preferrably the same type. If you raid a mismatched pair then your new raid "drive" will the the size of the smallest, losing the remaining space on the largest.

Multiple RAID setups in one Xserve?

Hi hope you can help me, we are a small architecture practice in the market for a new server and we are considering an Xserve and Xserve RAID system. I would quite like to set up the Xserve unit to use two of the drives in RAID 1 to mirror the operating system. My question is it possible and/or wise to have multiple RAID sets in the Xserve RAID unit? For example using four of the bays for 4x500Gb in RAID 1 (1Tb storage) for projects, and then using another 2 bays for 2x250Gb in RAID 1 as well for say Mail, maybe even another 2 bays for holding user home accounts. I understand that with share points this isn't strictly necessary but it seems to make sense to keep functions separate across hard drives for quick replacements. Or is this a lot to ask of a single RAID controller?
Also how easy is to add storage to an existing RAID set-up without destroying the data?; say we wanted to increase the 1Tb project storage to 2Tb easily.
Thanks for your help in advance.
Mac OS X (10.4.8)

Andrew,
I think you are over complicating you setup.
If you do multiple RAID sets the you are really anti-optimiziung. If you asked "How can I get the least performance and lowest capacity out of a RAID?" then I would suggest three mirrored disks w/ spare per controller.
You would have far better performance and capacity if you were to put two drives in the Xserve to mirror, then set up your RAID as RAID 5 across 6 disks with 1 spare (default config).
With Disk Utility you can build multiple file systems on the RAID, so you could slice it up, but again that could be wasting space.
When you get the RAID setup as one file system do not share the root. Set up sub dirs to share:
/Volumes/Raid1 --your RAID root, aka mount point.
/Volumes/Raid1/Mail -- mail
/Volumes/Raid1/Users -- Home dirs
/Volumes/Raid1/Projects -- your production storage
/Volumes/Raid1/Backup -- Save disk images of your server and workstations here.
And yes, changing the size of a file system means wiping it out and restoring from backup.
Also consider the 750GB drives, it's a lot more storage for not that much more money.

Having Multiple Adobe PDF printers with different output settings

Hello,
My company is using Adobe Acrobat X and XI on Win 7 Pro, and we would like to create 2 separate Adobe PDF printers that have 2 different output settings. So I installed a second Adobe PDF printer using the same Adobe Converter Driver as was used to install the first one. Then, I went into Devices and Printers and I edited the printing preferences of one Adobe PDF printer, but what I found was when I changed the preferences of one printer, it automatically changes the other one as well. Is there a way around this?

Thanks for pointing me to the iTunes Folder Watch program. It looks like this will solve my immediate needs. It's a little clunky in spots, but does handle adding new files very well. And it only cost about $10 to get the fully functioning version with the automatic monitoring in the background.
I copied the iTunes library files to each account, setup a watch folder that points to the location of the iTunes library content and all the music syncs up perfectly without duplicates. I have yet to test the applications, but music, movies, TV Shows, audiobooks, and podcasts all work fine.
If anyone else is considering this product, just make sure you double check your file location in the iTune settings to make sure each account is pointing to the same location and is organizing the content in the same way or else the individual account libraries will fight against each other to organize all the content where it is configured to put it. Copying the library files isn't enough since some of these settings are in the Windows Registry.
I made this mistake at first. I had all the accounts pointing to the same folder, but one of them (the original) had the "Upgrade to iTunes Media Organization" turned on which categorizes all content into folders based on type such as music, movies, podcasts, etc. Since the others were organizing just based on artist and album this caused the accounts to try to reorganize the files when Folder Watcher would tell it there were new files to manage.
All in all, this solves most of my concerns, but I'm still surprised Apple hasen't added this natively into the iTunes product. Especially when this guy figured out how to write the software to do it and is only charging about 10 bucks to do it. Well I hope this guy makes a million bucks off his little product bacause he surely deserves it!

Building an editing raid setup with an areca 1220 (8 port)

and here's goes yet another "what should i do raid-wise" question:
gonna build another editing station using some extra parts i have laying around. board is an asus x58 with a intel 980, video will be a nvidia 470. i found my old areca 1220 which i know is a little long in the tooth but would be nice to get some more use out of.
doing a little research i found some articles on what kind of speeds im looking at with it. its obviously not quite what a shiny new card would give me but im hoping with a faster pc and faster drives (articles are from 2007) it'll give decent performance for what i need.

http://www.tomshardware.com/reviews/RAID-SCALING-CHARTS,1662.html (raid 5,6)
ill buy all new drives for this machine (os, media, etc...). i know harm likes his raid 3 thing and im hoping he pops in with his expertise. so my question is how should i go about my complete disk setup from scratch here? type of disks? how many? which raid setup?
My budget is $1000 for the disks. also i mostly edit hd from my mark iii. im using the ml raw hack for about half my shots (and growing). pp cs6, ae cs6, cinema 4d r14 are my progs, though im a cc subscriber and will be integrating the new cc progs into my workflow over the next month or 2 as they work out the bugs/kinks. TIA

With 8 ports available your choices are somewhat limited, but then your budget for the drives is adequate.
You did not mention how much storage space you need, so I will assume 6 or 12 TB net space is enough for your purposes.
If 6 TB is enough, you could look at Seagate Constellation ES 1 TB disks and keep the rest of your budget for the future, if you need 12 TB you could look at HGST Ultrastar or Seagate Constellation 2 TB disks. I would only suggest enterprise drives.
With 8 ports I would configure them as 7 x raid3 or raid5 plus one hot-spare, giving you a net capacity of 6 disks, protection against failure of two disks and a sustained transfer rate of around 0.85 x (N - 1) x T = 0.85 x (7 - 1) x 150 = 765 MB/s. My preference is raid3, but you already know that.
The advantage of this setup is you have double protection in case of disk failure, you have a very high transfer rate and it is easy to administer. Using two arrays reduces performance, reduces protection and is somewhat more cumbersome to administer.

Native Mode
S-ata only
sata and pata both active
pata channel both
config sata as raid yes
How do i reconnect my 2 Maxtors.. physically? I presume on IDE2..?
And is it a problem that one 1 of those Maxtors an old version of XP is installed?
And yes during the RAID setup i dissconnected my 2 Maxtors..
