Raid partitions gone

I use a software RAID 1 aka mirror for backup since Tiger. I also used it to backup some data because of Leopard upgrade (did a fresh install).
After install of leo, i connected the raid and it worked fine, turned one Time Machine and did a backup of my iMac to the raid and copied some data back to the iMac (not all, ****:( )
I umounted the raid and mounted it on my mbpro and did also a backup with Time Machine, which also worked fine. After the backup i unmounted it and turned it of.
Today i wanted to get the rest of the data to the imac, so i connected it to the iMac and the system told me that it can not read from the drives. For both drives of the mirror i had the option to initialize or ignore it. I choose ignore an had a look into disk utility.
It only shows me one partition per drive with no option to do anything, except make a new partition.
The raid consists of two 300GB disks connected via firewire.
Here is 'diskutil info' for one of the drive
/dev/disk1
#: TYPE NAME SIZE IDENTIFIER
0: FDiskpartitionscheme *298.1 Gi disk1
1: 298.1 Gi disk1s1
so disk1s1 has not partition type, the same on the second drive only disk2s1.
I tried DiskWarrior but it only showed me unsupported drive.
Then i tried fsck with this result.
Alternate super block location: 0
** /dev/rdisk1
BAD SUPER BLOCK: MAGIC NUMBER WRONG
LOOK FOR ALTERNATE SUPERBLOCKS? [yn] y
SEARCH FOR ALTERNATE SUPER-BLOCK FAILED. YOU MUST USE THE
-b OPTION TO FSCK TO SPECIFY THE LOCATION OF AN ALTERNATE
SUPER-BLOCK TO SUPPLY NEEDED INFORMATION; SEE fsck(8).
Anybody an idea to get the raid volumes back?

The problem is that I can create the partitions prior to doing the RAID, but once the raid is setup there is no option to partion later AND if I partition prior to the RAID, Disk Utility will not let you drag A1 or A2 and let it be mirrored that way, it will only let you mirror and entire drive.
I continued searching after I had posted, and apparently, Apple did not include the ability for this in Disk Utility (a software RAID only) and the only way to accomplish this is through a hardware raid or the purchase of a software utility like SoftRAID.
Thanks.

    I see from your screenshot that you have added a partition- and in the process the hard drive was converted from Basic to Dynamic. This always breaks Recovery function..
    You will have to delete the extra partition AND convert the hdd back to Basic. Use "Option 1" here:

  • Change all the SoftWare RAID partitions to the VLM (physical volume)

    My PC has a RHEL5.0 system and other 4 partitions(Software RAID type). Now I want to change all the SoftWare RAID partitions to the VLM (physical volume) partition and I do not want to reinstall the RHEL5.0 system.
    How to do it?

    Hans,
    I am using ASMLib and no raw partitions. All the

    mounted by any system.For the partitions to be used by ASMLib the partition must still be known to the machine.
    From the ASMLib pages:
    "Every disk that ASMLib is going to be accessing needs to be made available. This is accomplished by creating an ASM disk. The /etc/init.d/oracleasm script is again used for this task: "

  • 400GB Raid partition disappear -after file transfer from USB2 HD

    Hallo, I have now been using my system prodly for two months, or so.   But under a filetransfer from my removable USB 2.0 HD, a disaster happened   An error message that said; Faulty writing. And my 400GB was gone from Windows    
    I have checked the raid drivers, and reinstalled them, and I can see at start up that the raid array is functional. With Seagate tool I can see that there is a partition of 400GB. What has appened      
    Anyone  I have over 200GB of Movies on that partition, any solution on this  
    How to make Windows see the raid array partiton agin   
    I use still winXP SP2

    Sorry for the late feedback, think I had to repress it for a while, the los of 200Gb
    I used stripe Raid 0 for better speed...
    Now I have given up Raid, so Iam using the IDE 3 & 4 as regular IDE connection for HD's. 
    So now I have started from scratch again .

    Hi,
    My motherboard is a 694D Pro AR (MS-6321, rev 1)
    This has onboard Firewire (IEEE 1394) and onboard RAID (via the Promise Fastrak100 RAID controller built on the board).
    The Operating system is in an IBM 45 GB. disk. attach to
    IDE 100 controller 1. The system is 100% stable.
    I buy 2 new Hard disk (Maxtor 60 Gb. 7.200 each) and make a raid with them (120 Gb.) in promise bios.
    I Start NT, all ok, and recognise the 120 Gb. partition, but
    Occurs the following:
    -- If i write data from the hard disk 1 (IBM 45 GB.) to the 120 Gb. partition all is ok and fast.
    -- If i write data from disk 2 (120 GB. partition) to the disk 1 all is ok and fast.
    And now is the problem, if i write data from disk 2 (120 GB.) to another directory of this disk the system become slowly and CRASH.

  • [SOLVED] (U)EFI dualboot Win7 Arch Linux - partitions gone - recovery?

    Hi everybody,
    I have a slight problem with my (U)EFI dualboot system (Windows 7 and Arch Linux) which used to be configured using rEFInd like it is described in my previous post:
    https://bbs.archlinux.org/viewtopic.php … 6#p1300356
    <EFI PARTITION> is /dev/sda1 and I used to boot via <EFI PARTITION>\EFI\Boot\Bootx64.efi which then successfully either loaded Windows or Linux kernel.
    Thanks to my own stupidity and a recent update of refind I decided to copy the new driver, font and icon folders to the <EFI PARTITION> in order to be up-to-date.
    After doing so, the rEFInd boot menu had a third icon which said "Boot via \EFI\Boot\Bootx64.efi" and if I clicked on it a second rEFInd boot menu appeared with only the two icons for Windows 7 and Arch.
    So I figured I could delete Bootx64.efi and ultimately did so, unfortunately. Afterwards I couldn't boot neither Windows nor Linux anymore.
    Following this I went through my noumerous USB boot sticks in order to be able to recover the Bootx64.efi. Unfortunately the first USB stick was a Windows XP one which has the plop bootloader alongside:
    http://www.plop.at/en/bootmanager/thebootmanager.html
    Out of couriousity I entered this bootloader and found HDA and HDB (I assume resembling my SSD and my USB stick).
    To my knowledge I didn't change anything but after entering the bootloader again I just found HDA left, HDB seemed to be gone. But I didn't think of anything bad happening yet.
    Then I found a working Archiso which I booted and using blkid I couldn't find the partitions of my earlier system anymore, only its device and the USB stick:
    /dev/sda: PTUUID="..." PTTYPE="gpt"
    /dev/sdb1: UUID="..." LABEL="ARCH_201312" TYPE="..." and so on
    /dev/sdb2: SEC_TYPE="msdos" and so on
    Even within the EFI shell I could not detect any internal drive anymore (only fs0: which is the USB stick)
    Using Archiso onboard tool testdisk I could find the old partitions. The correct result of the GPT from testdisk is:

    Issue resolved If you care to know how, read on:
    Looking at the disk using gdisk was doing no good. Neither of the recovery options in gdisk did the trick.
    I then returned to testdisk and restored the partitions (successfully). However, afterwards I was greeted by shell telling me the root device was not found (seems like UUIDs get changed when one restores them using testdisk). Adjusting the PARTUUID for root in <EFI SYSTEM PARTIITION>/boot/refind_linux.conf did the trick and I could boot up Archlinux again.
    Windows 7 still didn't boot telling me the required device was inaccessible (probably wrong UUID, too). I could however not restore/edit Windows' BCD using bcdedit, see my post Status: 0xc0000225 boot selection failed; required device inaccessible:
    To make a long story short: Removing bcd and running autorecovery from withing Windows RE successfully created a new bcd. Unfortunately, Windows writes its backup bootloader at <EFI SYSTEM PARTITION>/boot/EFI/Boot/bootx64.efi. This file originally was a copy of refind_x64.efi which I need to put at that location to be able to dualboot. After chrooting to my Arch system I could restore bootx64.efi, create a new fstab and everything is running fine now again.
    Best regards and thanks for the help.

  • RAID partitioning with existing data

    Hi,
    I'm planning on resizing my OWC Mercury Elite Qx2 (RAID 5, 8TB( 6TB)) to 1TB partitions each in order to avoid the FW800 issue, which slows the port speed down. Only problem is, there's a fair amount of data on the drives (approx. 65% used space).
    Now I'm not sure, whether it is safe or not to repartition with the data on it. I got a backup of all the files, but all on different drives. Recopying them to the RAID would be a pain.
    I tested the above with a 2TB (half full) drive creating three partitions. The speed increased significantly up to 20%. Do you think I could achieve the same with a RAID5 or are there other issues involved I haven't thought of?
    Any hint would be greatly appreciated.

    There are lots of workarounds:
    Use Disk Utility running from a DVD.
    Use Disk Utility running from an external drive.
    Use Disk Utility running from another Mac using FireWire target disk mode.
    Split the source mirror, remove one source drive and copy from one instead of the Mirrored pair.
    Copy the mirrored pair onto a backup. Remove the pair and restore from the backup.
    depending on which Mac model you have, use Optical drive connectors (2009 or later) or "hidden" ODD connectors to add an additional drive.

  • Xserve G5 won't boot off Hardware RAID partition

    I'm running an Xserve G5, 2.0 GHz single processor, OS X Server 10.4.5 with an Apple Hardware RAID card with 3 500GB drive modules in a RAID 5. The RAID is partitioned into two partitions, one for the system and one for data. After installing a video card, the Xserve will not boot off of the system partition on the RAID. It will boot just fine off a clone of that exact partition on a firewire drive, which is how I have it functioning at the moment. I have tried erasing the system partition on the RAID and re-installing the Server software but whenever I try to boot it it gives me the flashing folder Icon. I have tried resetting the NVRAM as well as restoring the functional backup of the system to no avail.
    Any ideas? (I have run disk utility, DiskWarrior, repaired permissions etc.) I also checked the status of the RAID and it is in optimal condition. The data partition seems to be just fine and the system partition seems normal when booted from the external drive.

    Harry, I just saw your post. I went through the same pain last fall, and it WAS resolved through Apple Support, but you aren't going to like the solution. Simply as background, during the pre-deployment testing of our Xserve, we were having problems with the Apple BTO SCSI card (really, an LSI Logic 22320) and swapped it out with an ATTO UL4D. Something in the card removal/replacement caused our Apple Hardware RAID card to go into the same mode as yours, where it would work fine as a RAID 5 (two LUNs, 50 GB and 417 GB, over 3x250 GB ADMs) but would not boot. Apple Support and I concluded that something had become corrupted in the firmware or boot code on the Apple Hardware RAID card, but they did not have a file to use to flash it, so they swapped out the card under our support contract, and that fixed it. I still believe that, if I had had a file to flash the card with using the megaraid command, that the original card would have been fixed. FYI the new card has Firmware Version: A131, BIOS Version G117, the old card had Firmware Version: A130, BIOS Version G117. Completely unrelated to this, I've had a RADAR bug report (RADAR #4350243) open since last November that the Apple Hardware RAID card fails to fully flush its write caches on graceful power down. I've got a test case that is 100% reproducible, causes mystery garbage blocks from space. I'd suggest that you turn the write caches off on all LUNs on your Apple Hardware RAID card as a workaround until this is fixed. LSI Logic (the Apple Hardware RAID card is a rebranded LSI Logic card) found and fixed this bug on a later firmware rev from Apple's version. No update is available yet from Apple.

  • Bios RAID Partition Not Detected at Boot

    Hello everybody,
    I've got a problem that's really a minor annoyance.  I have two 1TB hdds set up in RAID-0 and my system (Arch x64) on a separate ssd.  When I boot up, the RAID volume is not detected automatically.  I have to manually run partprobe, then the partition is detected and I can mount it as expected.
    I've been unsuccessful as to finding a solution and was hoping you guys could help.  Any ideas?
    Thanks in advance, and let me know if you need any more information.

    Yeah, it's a Gigabyte GA-Z77X-D3H motherboard, and I'm using the two Marvell sata ports for the RAID.  It's detected and works flawlessly in Windows; the RAID0 volume is formatted NTFS.
    And, like I said, when I load up Arch, after I run partprobe as root, I can mount and use the volume just as well as I can in Windows.  I'd just like to have it all done automatically.

  • External HD crashed by Disk Utility and all partitions gone

    I had a 320GB Seagate external hard drive with 3 NTFS partitions.
    They are 200GiB, 40GiB, 38.1GiB
    I tried to format the middle partition into an Mac Partition and failed. After that, all partitions are gone and when I plug the HD into a PC, the disk manager recognize the whole space of disk as free.
    the Log of the Disk Utility is as follows
    2009-06-17 21:38:50 +0800: Preparing to erase : “PERSONAl”
    2009-06-17 21:38:50 +0800: Partition Scheme: Master Boot Record

    2009-06-17 21:38:53 +0800: Erase complete.
    Then a new "disk2" appears in the Disk Utility and can't be ejected easily. There's also something like picasaUpload stuff bumping up during the short formatting.
    I tried to recover it using DiskTest 6.11 but it appears to take 14 hr to scan the whole disk and will not necessarily fix the problem.
    I have Anyone have suggestion on how to recover the partition? The 200GiB partition is really important for me.

    NTFS partitions can not be readily altered to begin with, and when there are multiple such partitions on a drive you should not attempt to alter only one. Since Disk Utility basically can't manage an NTFS partition, when you tried to alter the 'middle partition' (which in most cases is really a 'sub partition' or secondary partition to the 'main' or primary partition) you destroyed the whole of the volume's data structure. Unless you use a data recovery service or use data recovery software yourself, your data is gone. You should not attempt to alter NTFS formatted drives from Disk Utility.

  • RAID set Gone! on restart of XRAID

    Here's the scnario:
    at 3:20 pm I get calls that the xserve is stalling on people. Not usually a big problem, so I look into it, and It's stalled to the point of no GUI interaction on the server itself. Auto restart had not yet initiated, so I go ahead and use Server Admin to tell it to restart.
    Server comes back up with one problem, It only sees the left side of the XRAID. I open RAID admin 1.3.3 (firmware on XRAID is 1.3.2/1.26a) and it sees everything normally, Left bank is 4 250 drives Raid 5 and 3 250 hot spares waiting to be added to this raid, and right bank is 7 400s in RAID 5) So I shut both Xserve and Xraid down normally, and on restarting the XRAID and Xserve, only the Right side now appears on the Xserve desktop.
    In RAID Admin the right raid appears but the left bank only shows the drives, the RAID volume is no longer there.
    After talking with Pro support, they say everything appears to be working correctly, after reseating the Top controller, shutting down several times, no cache batteries, etc. All that is left to do apparently is either send the drives in for data recovery, or recreate the RAID again and populate from the latest backup.
    Any ideas? I currently have a backup restored to an alternate volume in the hopes of a quick fix, but I'm stumped and so is Apple!
    P.S. The RAID in question housed my User directories for Network Homed users.

    Ben, Scott, and Everyone,
    I'm glad I'm not an IT guy!!! I am however, a high end video guy so you can only imagine the abuse I give the XRAID units by hitting them over and over and over again with High Definition video running at 150Mb/sec+ for hours on end...
    I have seen the mounting problems you describe, which usually we resolve in our facililty two ways:
    1) Restart and restart and restart; the computer, the upper and lower controller, the XRAID, etc. If it takes power, just keep restarting it. Also, we are not adverse to powering down the units "correctly", and then still seeing trouble, pulling out the power cords, reseating everything and then firing it all back up. That has honestly worked more times than I care to mention!
    2) And if all else fails... I've been known to simply stick a new set of controllers into the units that are acting goofy... amazing what a new set of controllers will do for a 2.5TB first generation XRaid!!!
    3) If the thing seems really gone, I've had some success remounting RAID volumes (Raid 5, Raid 0, Raid 5+0) when using Drive 10 software, which has proven to also be very passive in getting drives remounted if some corruption has occurred.
    And yes, if a drive does remount, we back it up to something in case the whole unit is "crumbling."
    But to put it in perspective, XRAID units are the best thing we've got in the HD and SD video post production world... honest. At least they give me a fighting chance with real redundancy that works (trust me, I've replaced drive modules from a Raid 5 set and not suffered for it) and the data rates are really pretty good for what you're getting and that RAID Admin GUI is not all that bad compared to some of the others I've been forced to use.
    Sincerely hoping nobody experiences any more "meltdowns" in their tech lifetime... though I doubt it, cause were not working for Maytag...

  • Raid partition

    hey,
    I'm thinking of configuring a raid 10 on partioned drives and wonder if that would be a good idea.
    Before i had a osx server running on a powermac G4, with two drives. each drive had 3 partitions. One for the system and two that contained the homefolders for two different network user groups. I duplicated these partitions on a daily basis to the partitions on the second drive in case drive one would fail.
    Now i would like to install the server on a intel macpro with four drives and i'm thinking of using a raid 10. But would it be a safe strategy to maintain the partitions. Which means partitioning all drives, mirorring partitions and striping mirrorred partitions! It works. I tried a raid 0+1 and a raid 10 on four drives that all have 3 partitions. But would it be safe or stable!
    thx a lot

    I have found Softraid exemplary. Very responsive customer support (several years ago there was an issue with an upgrade of os X and compatibility of softraid with diskwarrior and their responsiveness was outstanding). You can do raid 1 and raid 0. Works very well and I think it is much more secure and "recoverable" (at least the mirror setup) than apple os X mirror raid - its auto-rebuild feature is much more robust than os X version for example. Softraid also has extensive reporting/logging facilities. But it doesn't do raid 10. Still, I like it and have found it very reliable with no noticeable overhead costs on the system.
    I have used softraid for both mirror and slice raids, I'm back to the mirror setup for security reasons now as I found that in real world use, the stripe wasn't really noticeably faster (I don't make lots of copies of huge numbers of files regularly, and although I use aperture, it is not my main app, just a hobby). Plus, with a stripe I needed an external backup drive that slowed my system down as it would often put itself to sleep (even though I supposedly have that disabled in os x), thus resulting in a slowed system when I had to wake that drive up and on startup.

  • Disk Utility : Partition / Raid or Raid / Partition ?

    I have two external USB drives that I'm attempting to set up using Disk Utility.
    I'd like to create either
    - one RAID1 set with two partitions, or
    - two RAID1 sets with one partition
    however I'm not having much luck with either option. Is either scenario possible?

    After some experimentation, I seem to have come up with a kludge ...
    Partition both disks into identical volumes (A1 = B1, A2 = B2)
    Using Disk Utility :
    - create RAID Set 1 ( A1 + B1 = RAID1)
    - create RAID Set 1 ( A2 + B2 = RAID2)
    Error message 'Creating RAID set failed'
    Restart ...
    Using Disk Utility :
    - click on partition A2 (now renamed RAID Slice)
    - Erase partition
    Upon erasing the partition / RAID slice will remount and the Disk Utility should show two RAID sets. A cursory examination of each RAID set's behavior leads me to believe it is simply a bug in Disk Utility that prevents the creation of two RAID sets on the same disk pair.

  • Windows Partition gone after updating to Yosemite

    Hello I have recently updated to Yosemite and was unaware of the bug that causes the partitions to disappear.
    I have read threads and the steps are way too difficult to understand and all i see is coding and other things.
    If anyone could help please (step by step) in a simple way.
    Windows 7 Partition shows up as disk0s4.
    Macbook Pro 13' in 2012.
    Have downloaded TestDisk but have no knowledge in how to use it.

    And I have a couple of questions to the steps below:
    1. Delete the old entry and create a new entry at GPT#4. (Is this step done in testdisk? If it is, what are the steps to get to this step?)
    sudo gdisk /dev/disk0
    p
    d
    4
    n
    4
    86923264
    538218489
    0700
    p
    w
    y
    2. You will need to reboot after the change, because the disk you are booted from is the one being modified. Reboot will rebuild disk0s4 using the start/end you entered.
    3. Run the dd command - sudo dd if=/dev/rdisk0s4 count=1 2>/dev/null | hexdump -C and check that the first line contains "R.NTFS". (Done in testdisk?)
    4. This is a tedious process and you want to check after the second 'p'rint command that it looks reasonable, before the 'w'rite and 'y'es to confirm. (Testdisk?)
    5. Once you a working GPT#4, a new hybrid MBR needs to be created which will overwrite what you see in your Fdisk output. This is also done using GPT Fdisk (Gdisk). (Download link to Gdisk?)
    6. a. Test 1 - Can you see your Bootcamp volume in Finder.
        b. Test 2 - Can you files in the Bootcamp volume?
        c. Test 3 - Can you see Bootcamp in your System Preferences -> Startup Disk.
        d. Test 4 - If Test 1-3 are successful, select Bootcamp and click on Restart. You may need Windows startup repair, if you see a hanging underline cursor at the top left corner of your screen. In most cases, it is not required.

  • Raid BIOS Gone (KT4 Ultra-BSR)

    I recently bought a Serial ATA Hard Drive wanting to install it on the raid controller.  But when I went to enter the Raid Controller's BIOS FastBuild Setup (at boot-time), it never shows up.
    I have the KT4 Ultra-BSR, and I can see the RAID Controller enable/disable option in the Integrated Peripherals.  I have it enabled, but it NEVER  displays the RAID bios at boot-up.  This is the second KT4 Ultra I've had and I know I saw the RAID bios on the first one I had. I have the latest system BIOS installed (1.30).
    Has anyone experienced this and/or know how to fix it? Is there a way for flash the RAID controller to possibly fix it?  Did the entry to the setup change from whats in the manual (ctrl-F4)?
    Any help is greatly appreciated. Thanks

    I've seen a couple other post like yours Shark. While that makes me feel a little more comfortable that other are having similar problems, I thinks mine's a little different.  I don't ever remember seeing the RAID BIOS on this motherboard.  I've tried turning it off and on in a row to see if mine would eventuall show, but I never see it.
    Does anyone from MSI read these? I think something should be done.
