Migrating Fedora to Arch with Raid

Hi everyone,
I am considering moving from Fedora 16 to Arch and I was wondering if anybody could point me in the right direction re:
1. special considerations and support when migrating from Fedora to Arch (preserving file structures)
2. I have a 4 disc Raid 5 lvm ext4 setup that I want to keep. It's about 4TB of data so very hard to backup. Any suggestions on what install risks I need to look out for? Again, just pointers to available resources would be great.
thanks,
Michael

answers;
1.nothing specific, Follow the beginners guide and you will be mostly fine.
2.Wiki again.RAID and LVM

Installation with Raid, etc... [dead issue, don't bother reading]

I'm trying to install arch using RAID and LVM, following the wiki procedure in Installing with Software Raid or LVM.
I am able to get to the point where I install the kernel. When I install it, the bottom of the screen flashes the "wrong fs type, etc" error, then the installer acts as though it is installing it anyway, going through the installation, configuration, and fallback configuration stuff.
If I continue, when I get to grub installation, I get the error that the drive doesn't exist. I've found some forum threads on this which indicate (I think) that I need to run makedevs before going to grub installation. If I type, makedevs, I get a command not found error.
The filesystem seems to be up and working, so I'm not sure what next steps I take to troubleshoot this.
bump:
So I tried the quickinstaller for some better control, which seems to help. I also found this in the forums, it allows me to run makedevs. /dev/md0 is already mounted at /mnt are my root, so I skipped the first line, not sure what else I could do there.
mount /dev/hdxY /mnt
chroot /mnt /bin/bash
mount -t sysfs none /sys
mount -t proc none /proc
makedevs
mount -a
Then vi /boot/grub/menu.lst :
kernel /vmlinuz26 root=/dev/md2 ro md=2,/dev/hda3,/dev/hdb3
Then launched grub as quoted in the wiki
Now, it doesn't say to exit the chroot to go on to grub - but it must be required because there is no /mnt/dev unless you do. Once out, if I use
mount -o /dev /mnt/dev, I get a new error:
mount: can't find /mnt/dev in /etc/fstab or /etc/mtab
Which it isn't, but /mnt/dev does certainly exist.
I'm working on the very edge of my linux knowledge here, and suspect I'm making a fundamental error, but (obviously) don't know what it is.:(
bump:
Found this in discussion about the current iso, no access to the computer today but this will be my next approach.
ok bug indetified:
i really apologize for this because it's something that shouldn't happen at all, but im only a human too.
/dev is not correctly mounted in installation system (during archboot cleanup i thought this is not needed sad )
--> setup cannot bind /dev to installed system.
--> autodetection of filesystem will fail, which will cause the default initrd to fail on boot.
2 workarounds:
First workaround before entering setup:
mount -t ramfs none /dev
/etc/start_udev
now setup works as it should!
Second workaround:
while using setup:
edit /etc/mkinitcpio to not include autodetect in HOOKS= array
1 workaround if you already installed and system doesn't boot:
use the kernel26-fallback.img as initrd in your bootloader
after successfull boot just fix the ramdisk:
mkinitcpio -p kernel26
bump:
I backed out and started all over a couple times, finally installed via Duke with updates. Found that I had to reinstall filesystems to my hard drive; something obviously got messed up, and ultimately found a couple of "typos" that had managed to mess me up. Because I fixed so many things on the way to installation, I can't tell you exactly what I did, so I'm marking this thread as a dead issue so people don't bother reading it.

I've been using LSR (Linux Software RAID) with Arch for a while now and it's never given me any trouble: I don't even know how that works since all I have to do is make sure the md module and the appropriate module for your RAID-type (in my case raid0.ko) is loaded: when these are compiled into the kernel, the md-module automagically finds my RAID-partitions and starts the correct md-devices in /dev.
I don't have any md-daemon running (I didn't even know there was one until I read your post).
And still everything just works.
What I think you need to do is repartition both of your RAID-1 discs and make sure your partition's type is "Linux raid autodetect" (type fd). Once you've done that, create the md-device and put a filesystem on it. Edit /etc/rc.conf and put "md" and "raid1" in the list of modules to be loaded at boottime, get rid of the mdadm service since it doesn't exist anyway.
Now after rebooting, once the RAID-modules are loaded they should detect and start up your RAID-array automagically. Check this with dmesg.

Windows XP 64 bit pro clean install with RAID

Can anyone help out???
I recently purchased a Lenovo Thinkpad W700 with the raid system (raid1) it had Vista Business pre installed but I wasn't impressed so I've cleared VB out and tried to install XP 64 pro I have followed the guide I found on this site http://forum.notebookreview.com/showthread.php?t=188992
which was very informative but didnt seem to include any details on a raid installation. If I change my BIOS Serial ata (sata) to compatibility I can install win xp and get it running but no raid!! if I try to install the Intel chipset driver it reports it cannot install!! If I set the Bios Serial ATA to RAID the setup goes so far through then I get the BSOD
I seems to me I need some raid drivers but have no way of installing them during setup (I dont have the drivers anyway!!)
Sooooo...........can anyone out there point me in the right direction for a clean xp pro install with raid?? theres a couple of beers in it!!
Lenovo thinkpad W700, Q9000 2.00GHz Quad Core 2x 160gb hdd raid1, 4gb ram, 1gb nvidia graphics FX3700m Fingerprint reader, Graphics tablet (digitiser?)
Windows 7 Professional 64bit RAID 1

I believe you need to install the Intel Matrix Storage Manager Driver for Windows XP, Vista (32bit) - ThinkPad. Installation instructions are on the same site. If you don't have a floppy you can streamline them onto an install disk.
Other drivers can be found here.

Anyone else having problem with RAID and iTunes syncing photos in Vista?

Hello,
For whatever reason iTunes can not load some of the photos from C drive. It can do it from D drive, though VERY slow. Both C and D are NTFS system, but C is a RAID 0 drive (implemented by hardware on motherboard, Intel 82801G controller). I just wander if this is something related to iTunes not working correctly with RAID drivers, or is it something else? I should say that ALL other programs and games working fine on this drive.
Thanks for the replies.

The problem is with Windows Vista using the NTFS file system, check out this post for the official solution. This has worked perfectly for me everytime I've tried it:

Interesting problem with RAID, Windows 2008 server, and Ubuntu

sooooo, i got the system working and linux loved it. just adored it.
however, Windows did not. Windwos 2008 server hard locks from time to time. i fianlly figured out that it had to do with the RAID 0 i was running, that didn't really succeed.
However, when i rebuilt the RAID and everything on it, it refuses to recognize the disk, sayign that windwos cannot determine if this drive has a valid system volume on it.
Ubuntu 9.04 server, however, just took it and made it work great.
I enabled the PCI Bus SATA to be Master in the BIOS, and then Windows Server 2008 said that it could not determine if the drive was bootable. Then i went back and redid the raid, and it did the original error.
I inserted a windows xp disk, destroyed the RAID, and then installed the software on a NEW disk. While it installed fine, it gave me an IRQL_not_less_than_or_equal error. It boots in safe mode, but no where else. I tried installing the NVRAID and MCP55 drivers in safemode and what not, but still, it refused to cooperate. I went back to ubuntu, this time the desktop/workstation versions, and i am doing an alternate install with RAID...much to my disappointment becuase now i will have to use VirtualBox to isntall windows...and if that fails, i'll be really pissed.
My settings are as follows:
SATA Controller 0-5 enabled
NVRAID- enabled
PCI BUS SATA- Option ROM Enabled, Master Enabled, and 0040h latency
MAC LAN- same as above
MAC LAN1- has master disabled, but the other stuff is the same
Serial port A is on AUTO, B is disabled, and floppy is disabled.
Option Rom is PFA relocation.
Also, my AEC A6880 is giving me a ROM expansion error, even though, in both OSes it can be seen....usualy. I just want to fix it
lastly, my LSI PCI-E scsi adapter is not being seen at ALL.
thanks guys.

What's the BSOD error? Are you using XP installation disk with included SP3?

Need urgent help with RAID failure on Graphics server (running OSX10)

Hey.
Here's the deal... Our graphics department has a MAC G4 (fully upgraded. newest patches, OS, etc.) that's got a 4 port SATA RAID controller. They use this with four 750GB hard drives as an external RAID (the OS is on a seperate, 65GB hard drive). The way it's set up, through Apple's OS, is we have the four 750GBs in pairs... those pairs are striped, and then the two sets of striped 750s are mirrored. This has worked just fine for a number of months, but we recently had a power surge, and now we're unable to mount "Monkey" (the name of the 1.4TB array).
See the below screenshots for more clarification.
http://www.amcdoors.com/lorenzo/raidsetup.JPG
This shows the RAID card, and the four SATA cables coming out of it.
http://www.amcdoors.com/lorenzo/leftside1.JPG
As you can see in this and the below screenshots, this shows the 1.4TB Striped set as 'online', but the two below (the two 750GB hard drives) show up as "offline".
http://www.amcdoors.com/lorenzo/leftside2.JPG
this shows the actual drive i click on. same thing
http://www.amcdoors.com/lorenzo/leftside3a.JPG
If i click the entire array, you can see how it's set up (the Mirrored RAID set consisting of the two Striped RAID sets). The RAID sets (all 3 of them) are showing up as online, yet the drives are offline. No idea why. The drives are all powered, and are spinning, and plugged in.
http://www.amcdoors.com/lorenzo/leftside3b.JPG
when you click "Monkey Drive", nothing shows up in it. i don't remember if anything ever used to. if you click 'mount', nothing happens.
http://www.amcdoors.com/lorenzo/leftside4.JPG
http://www.amcdoors.com/lorenzo/leftside5.JPG
this shows the exact same problem as the first RAID set.
http://www.amcdoors.com/lorenzo/verifyRAIDset1.JPG
If you try to Verify the RAID set, it shows that no repairs are necessary
http://www.amcdoors.com/lorenzo/verifymonkey.JPG
If you try to verify Monkey, you get a "Volume Needs Repair" error... but when you try to repair it, you get this:
http://www.amcdoors.com/lorenzo/repairmonkey.JPG
Really need help; this is a pretty critical problem. Someone that's familar with RAID solutions on MACs please help me out. We can't risk losing any data if at all possible.
Thanks

Is it possible to install cue 8.6 on sre 900 with raid 1?

Hi.
Is it possible to install cue 8.6 on sre 900 with raid 1?

Dear John
Thanks for ur quick reply. I never used tis formum before, so I am sorry for being too unclear..
Anyway, what mean is this:
I want to buy a new laptop as my old lap top has Windows XP and 'suffers' from a lot of things! On this old lap top I have installed Premiere Elements 10, and I just want to know if the 'old' version 10 will work in Windows 8, as it is not mentioned in the system requirements here:

Can't install Win7 with Raid 0 on a K9A2 CF

Motherboard:    MSI K9A2 CF
DDR:     8GB (4*2GB)
Proc:      AMD Athlon 620
HDD's:      2*Hitachi 640GB (same drive models)
So the problem i'm having is that i can't get Windows7 to get installed in raid 0. I bought this set of hardware to do some experimenting with small business server 2008. I've installed SBS2008 in Raid 1, and seemed to work (but i've never crashed a disk to test it). The tests went fine, and since a month or two this PC/Server is doing nothing.
Now i've been trying to get Windows7 installed but can't get it going with a Raid 0 setting (that's why i'm doubting if the RAID 1 with sbs was working correctly).
First problem i'd run into was that my DVD wasn't accepted (missing device driver). I've created a bootable USB disk and seem to work.
The problem starts when i should select the disk.
First, i've setup the following in the RAID-Bios:
I've done it with 1 array, or with 2 array's it doesn't change anything.
In the normal bios (updated last night to the latest version, which actually slows the systems down during the install). I've selected RAID in this screen
RAID (i've selected RAID)
When i get the option to select a drive, it doesn't display any drives so I select the option to add a driver.
These are the drivers i've downloaded:
But when selecting these drivers I've get a negative response
(with or without "Hide drivers that are not compatible......"
When i download other drivers (I actually tried them all) i get some response:
But when i select this driver, it takes several minutes to proces:
But it comes back blank:
When i select in the bios other options (like IDE)
It comes default with a disk:
But this is half of the array (1 drive). When i try to partition it, it fails. So it isn't accessible.
Last thing: i've tested with all 3 available Bios options (IDE, RAID and AHCI) in combination with all (Win7, Vista and WinXP) drivers. But there are no differences.
I understand i made a long post, but normally i just figure it out myself with researching on the web. I have tried everything i can think of. But it seems that:
1. I made an error configuring the raid-arrays (with one big array, the results are the same).
2. I made an error in the bios? (setting should be raid, other settings i should think of?)
3. I'm working with the wrong drivers? I think i'm doing something wrong driver related but can't pin the problem.
4. Or... ?
I'm open to suggestions, i've run out of option. :(
Thank you.

Great link, seems to work. So after trying everything it was just a simple driver error.
I've tried the drivers from 1337 but they didn't work. But the chinese drivers did work:
http://www.rayfile.com/files/edf377e1-ec6f-11de-aad5-0014221b798a/
I don't know how or what. But the RAID console seemed to get 2 disks (2 raid arrays) and installed and formatted correctly from there on.
Installed Win7, booted and all the hardware was accepted.
If anyone has a line to MSI or someone from MSI is reading this: If needed i'm willing to run some kind of debugger if it helps. But otherwise I would suggest checking the drivers offered on the website because the drivers on the MSI website are faulty for some of your users. On the K9A2 they will not work with RAID with Windows 7 64-bit (the official drivers I mean).
Bas to answer your question: I have no particular interest in running a 64-bit operating system. But when it failed to work it became a challenge to get it working. I could have switched to 32bit immediatly but I don't like to give up the first moment something doesn't go as planned, and in the end I had so much time invested I just wanted it to work under 64bit .
Frederik, thanks again for the link, really helpfull. Thank you all for helping and giving suggestions.

Help thinking buying a W530 with RAID hardware or software

I'm thinking to buy a W530 with RAID. I have no experience with RAID and never thought that RAID is possible in a labtop.
I have read that RAID comes in types of implementation, software or with a hardware controller. In this forum I read that in the W530 service manual the RAID controller has been disappeared from the motherboard (I have not checked by myself).
Does anyone know if RAID is still implemented by a hardware and not by software.
Frank

From the forums and the rep I spoke with, RAID is implemented in the hardware. You will not be able to enable RAID later on if you did not order it like that from the factory.
You would probably be better off going SSD in the primary and a larger capacity HDD in the ultrabay. You'll have better speed, more reliability, and lower power consumption in general compared to 2 HDD in RAID 0.

Maximum no of HDD with RAID in 790FX GD70 ??

Respect to All experts !!
I have 790FX-GD70 in which 6x SATA II ports are provided by ATI SB750 chipset with RAID facility. I am currently using 2x Seagate 500GB in Raid 0.
I want to re-create it with 6x HDDs (Just for benching and self knowledge as I know performance will not be 6 times faster or even 4 times).
Can ATI SB750 RAID use all 6x SATA ports with Raid 0 ???,
because my friend has an Intel board named P7P55D Pro E and according to him he is restricted to use more than 4 HDD in RAID.

I am using 18 file adapters at sender side .
added 6 more in dev and UAT total 24 working fine in these environemnts..
my file adapters never gave me a problem unless and untill structure problem..

Mac Mini with RAID - 4x USB Drives

I've got an older Mac mini 2007 Core 2 Duo machine that isn't doing much since I got the MacBook so I thought about using it to replace my Windows Server.
I did want to have some form of redundancy attached to this server so I hoped to use 4 USB drives of 4tb capacity. I hoped to use two drives "doubled up" to get the capacity I needed (8tb) and another two to "mirror" the first two for redundancy.
I'm aware that OSX has RAID partitioning available but wondered if what I want to do is possible, has anyone tried this setup?

Thanks both for your thoughts.
I'm now having a rethink myself as USB2 does have limitations I want to avoid, and have come up with options:
A new Mac mini with USB3/Thunderbolt to speed up the throughput (I will be using it to stream HD to Apple TV, for the iPhoto Library and for Time Machine Backups) on which I would use either a Direct Attached Storage solution with RAID 5
or
A standalone NAS box. Is there a NAS that could do all three jobs? I guess it would have to natively format HFS+ because of iPhoto...and have an iTunes server and be Time Machine compatible. A tall order?
Thoughts?

Filename problem with RAID

All,
We have a problem with our Xserve RAID with regards to the way files are named. For example we have a file called "081bSelecting_SkyArea#18.tif" which will not copy to our RAID. If i was to copy this to our Xserve it would be fine, but as soon as it goes down the Fire Channel it says we have the incorrect permissions. As soon as i rename the file it works fine.
I under stand from the link below that there has been issues like this in the past with 10.2, but i am unable to find anything with regards to 10.3 server which is what we are using.
http://docs.info.apple.com/article.html?artnum=107144
Many thanks for your time.
Darren Senadhira

Not sure. That bug you're referring to has to do with file sharing (e.g. AFP or SMB), it doesn't say anything about direct-connected fibre channel.
Wish I had a server with RAID attached to tinker with this right now, but alas I don't at the moment. Any chance you can avoid using the #xx at the end of the file names?

NAS with RAID set up

I want to set up a NAS with RAID option. I have my imac (with leopard) and couple of PCs (vista) at home. I also have an xbox which i use media player (sorry no apple TV) for photos etc. Do you have any suggestion which is the best option that with support both PC and Mac. I would also like to use my NAS as my itune server and store my other media file.
I am not a digitally savvy person and am looking for a simple option.

I have been happy with the ReadyNAS line from Netgear (formerly Infrant). They have information and very active user forums where you can ask specific questions at: http://www.readynas.com

Mac Mini Server with Raid 1

Hi,
Is it possible to set up a Mac Mini Server with Raid 1 using only another mac computer such as a mac book?

Yes- Colin Jeukens posted step by step instructions back a couple of months ago. Here it is again...
Out of the box the mini comes without Raid. You have two identical HDs of 500Gb.
I have just set it up as Raid1. You can't do this when you use the startup disk from the mini. And as you don't have a Superdrive ... you need to be creative. You need another Mac with Firewire.
Step 1: Start the Mini in Target Mode. Press the T during start. In a few seconds the firewire logo will appear on your screen.
Step 2: Go to your second Mac. Connect the firewire cable between second Mac and Mini.
Step 3: On the second Mac start the disc utility. The two identical drives on your mini will show. Create a new Raid set (mirrored = Raid 1). Include both drives. Confirm the warning that all data on the mini will be lost.
Step 4: Make sure your second Mac has CD/ DVD sharing option installed. This is tou use the superdrive to install OS X Server on the mini.
Step 5: Shutdown both Macs
Step 6: Start your second Mac in target mode. Make sure the firewire cable is still connected.
Step 7: Start the Mini with the option key pressed.
Step 8: Insert the OS X Server install disc in your second Mac.
Step 9: wait till the drive logo apears om the Mini. Continue the install. Will take about an hour.
