HowTo : Recover Intel RAID "Non-Member Disk" Error.. - Page 11

[*] 2 x 2TB HDDs, set up as 1 x 4TB RAID0 array. (BIOS Name and OS Label:"STORAGE")




"SYSTEM" is bootable and contains Windows, now Win8 Pro x64, but when the problem
originally occurred, it contained Win7 Ultimate x64. The whole array is partitioned as a single
"basic" MBR partitiion, "Drive C:".

"STORAGE" is not bootable, and, again, is partitioned as a single "basic" partition, (except that
it is GPT), "Drive D:".

When I first had this problem about 6 months ago, I had no idea what to do, so I just re-created
the array and re-installed Windows, etc, etc... Data loss was negligible, as I store everything of
any importance on "Drive D:".

The RAID error was then, and still is, with the "SYSTEM" array; the "STORAGE" array has never given
me any problems.

Some weeks later, the same thing happened again, so I decided to try something else.

This is what I did:

NOTE: "Power down" means shut machine down, and then switch off at the power supply, or the mains outlet.
  1. Power machine down.
  2. Disconnect "non-member" disks.
  3. Power machine back up.
  4. Check that BIOS sees new config.
  5. Power machine down again.
  6. Re-connect "non-member" disks.
  7. Power machine back up again.
  8. Check that BIOS sees the disks.
  9. Watch RAID info and check whether or not error has gone away, (i.e., the RAID BIOS again sees the array as it was originally set up).
  10. In my case, this has fixed it every time, and no data has been lost.

In my case, the two offending disks are on SATA #0 and #1, and the cables are marked accordingly, so that I won't connect them in the wrong order.

I have no way of determining whether the problem is with the disks themselves, the ICH10R controller, or one (or both) of the SATA channels on the mainboard. It's too hard to use a process of elimination, (especially when, as in my case, the fault is intermittent), because I don't have a second MB with the same controller available.

One thing I have noted, though, (please bear with me, because this is a little complicated):

I have encountered this problem, (I am almost certain of this), only when re-booting the machine after having booted from a Linux live CD.

When I shutdown from the Linux CD, I get the error mostly if I let the machine restart without powering down completely first (i.e., I tell Linux to "Restart" rather than "Shutdown."

There are, unfortunately, quite a few Windows programs, mainly AV or backup-type programs, that use a Linux live CD as rescue disks.

This is actually quite a problem for me, because, for some unknown reason, Linux cannot see my RAID0 arrays at all, only the individual disks! I have searched all over the net for help on this, but to no avail!

The only rescue disks I can use are Windows-based, and a warm reboot from a Windows-based disk never gives me any problem at all.

If anyone here could give me any ideas as to what I can do to fix this, I would be very grateful!

Anyway, I hope that the foregoing procedure may be of help to anyone else experiencing this problem.

Best regards to you all!

I know this is an old post you made a few weeks ago but I wanted to shed some light into at least one thing you commented here, the one thing I feel confident I can answer correctly for you. Regarding linux seeing your individual disks and not the "Raid array" with your onboard. This is because the onboard "Raid array" on intel motherboards is -NOT A REAL RAID SOLUTION-, and you should not rely on it for any data redundancy what so ever at any point in time. The onboard is "Software-Assisted" raid or also known to those within the IT sector as "FakeRaid". The reason linux sees the individual drives is because linux is designed to only interface "multiple hard drives interfaced as one" (AKA RAID) when using an actual hardware raid controller / host adapter card. Being as the onboard raid on intel motherboards is "FakeRaid" it thusly is not exported as a "Virtual Drive" to the linux operating system as a real raid card would. Also (and this next part I am not certain 100% on, and I am just speculating) this is most likely why when rebooting from a linux live CD/DVD that it is triggering an "Error" with your raid array. It's possible linux (Since it does not understand how to manipulate "FakeRaid" correctly), is some how damaging your raid configuration. In fact just so you also know, about the onboard being "FakeRaid", you do not have the ability to rebuild a failed raid5 array from within the BIOS control center for the onboard RAID controller, you must only do that with software, from within windows. Real raid controllers let you initiate rebuilds from within their BIOS without ever entering any operating system.

Again, it is not an "Error" that linux does not see your drives raided, it's because of the design of the onboard raid. It is not possible to "do something" or change linux in a way to see the drives raided from an ICH10R. I own two ICH10R motherboards and I've tried every type of raid the ICH10R is capable of and every software option within the software control center, and I could not get linux to see a raided volume in either machine, only later through a friend of mine did I understand about it being FakeRaid.

Also linux -DOES- support A type of software-assisted raid configuration, but that's created from within the linux operating system and only works with linux, you could not dual-boot linux and windows both if you had that configured. You could consider looking for a used Dell Perc5/i on ebay. They're cheap (I got mine a month ago for $30 shipped) and a SATA cable is another $25 (4 drives per cable, 2 cables for 8 drives), and that's a full hardware raid card and it would work with windows7 and should work with all versions of linux.

Good luck with your endeavors and I hope this has helped you understand the ICH10R onboard on motherboards a little better.

SOLVED

I was able to save all my important data with ReclaiMe Free RAID Recovery -software. After you have found your parameters with this, you need one of these commercial data recovery programs to actually save your files:
File Scavenger
ReclaiMe File Recovery
R-Studio
UFS Explorer
Zero Assumption Recovery

Hello!
I messed up my RAID5-array somehow, while testing my HDDs with Ultimate Boot CD (Samsung diagnostics tool)
After that i got this "Non-Member Disk" problem.

My setup:
Intel onboard RAID-controller
1x 60GB SSD as boot (windows7 64bit)
3x 1TB Samsung Spinpoint F3 - RAID5 array

I did some research, and tried this:
1. Remade RAID5-array with same options as before.
2. Rebooted to Windows.
3. Ran Testdisk.
4. Found my RAID-array. Correct type. Correct size.
4. Selected EFI GPT partition table type as it auto-detected.
5. Started quick search. Problems start here. It's not quick at all. It will take ~20h to pass. Current situation:

Not looking good. It makes no sense to me. Any help is appreciated.

How was your array partitioned before? One big partition, or smaller ones of certain sizes? Also, what filesystem(s) on each?

I agree, that's very confusing.

I took a look at the TestDisk wiki. I couldn't find anything that directly relates to this, but I did find a line that may be helpful:
Quote:
Highlight this partition and press p to list your files (to go back to the previous display, press q to Quit).
I suggest highlighting one of the partitions shown and pressing P. In their example screenshot they used a Green partition. Try that one and try the bigger grey one below it. If you can see all your files... write the changes and pray? (Please don't hate me if it screws everything up. redface.gif You may want to wait a few days for someone else to give advice before going through with it - but do check if all your files are visible by pressing P.)

Glad I was able to help a couple of you guys. Wouldn't have been possible without Ictinike, and all the other people who have posted their setups and experience with trying this. I really mean that, I wouldn't have noticed the trend if not for all the user reports and the hardware configurations listed in their sig rigs.

RAID is RAID. Intel RAID is very much "real", very much "multiple hard drives interfaced as one" a redundant array of (presumably inexpensive) drives (AKA RAID), and is in fact capable of functioning in Linux.

The difference between a software assisted RAID solution such as what intel offers, and a dedicated RAID controller card, comes down to how much processing is done before reaching the operating system.

Good RAID cards have built in processors, memory for cashing, and some form of momentary power backup. they sort the information written to the drives and pass it to the system in a finished state, or vice versa.

Intel RAID solutions do not have dedicated processing or storage, and instead use system RAM and CPU clocks. This requires drivers to pass the data from the drives and their instructions to the CPU, and back to the drives.

It's these drivers that you do not have in a linux live CD.

Hi All!

Here I am, coming from google, with a 4 drive RAID5 on Intel ICH9R, with 2 "non-member" disks frown.gif

A quick overview of my setup:
- Intel Core 2 Duo E8400
- Asus P5K-E with Intel ICH9R
- 1 x 120 GB SSD for Windows and Apps
- 4 x 2 TB drives, on RAID5, with 6 TB of usable space, with a GPT partition
- Windows 8 x64

So, last night I shutdown my computer as usual. This morning, when I turned it on, I've noticed that for some reason, the BIOS settings reverted to default. The ICH9R BIOS wouldn't show up, and I can't quite remember if on the first boot the system got to the Windows 8 boot, but after some resets, I actually remembered to go to the BIOS and change the SATA setting from the (default) IDE back to RAID! After that, the ICH9R BIOS is back, and I can see 2 "non-member" disks on my RAID setup, and the RAID as "failed"! Panic!

I was able to boot into windows, and the Intel RST software showed me the same as the BIOS: the RAID is failed, with two missing disks, and two disks showing as "non-member", ready for my Windows consumption.

I started googling, and didn't do anything else to the machine, as I found out this and a couple other sites. I shutdown the computer and went to work.

Now, from what I've seen, there was a chance that everything would be fine with just some "unplug-replug" of cabling, if only I had just change the SATA parameter from IDE to RAID ore any actual booting, right? Since that didn't happened (I only changed it after a couple of boot tries), I'm assuming that the metadata on the RAID actual got a bit messed, so I will have to use Testdisk and the whole nine yards... Anyone might want to add some insight into this?

The first thing I will try when I get home is the suggestion from Chris4877, and see what I can do from there. Actually, Chris4877, during the times you had the issue, do you remember if the SATA setting on BIOS was ever changed?

Also, Chris4877 setup is two RAID0 arrays, so I'm afraid that on my RAID5, the situation might be worse :S

Anyway, I'm hoping to solve this with a minimal fuss, so wish me luck wink.gif

By the way, I had a couple of issues with RAIDs recently. I was using a 5 year old Fastrack controller that all of a sudden started to mark one of the ports as failed and messed my data... Grrrr, bad memories... I might actually invest on a dedicated, with CPU RAID controller, or perhaps a NAS with 4 bays (I have one but with only 2).

I'll update this later with the results.

Cheers!

Well, just a quick update... I had no luck with my issue frown.gif

I've done the shutdown and unplug part, and no luck. Even with the remove and create the RAID again, Testdisk was able to see a partition, but it was too large for the disk. I even tried with Paragon, which was able to recover the deleted partition correctly, but the filesystem was so corrupted that chkdsk was just deleting entries and basically trashing the rest...

I think that with the reboots and everything from my BIOS defaulting, the data on the actual disks got corrupted, so I just gave up on recovering anything.

Oh well, lesson learned smile.gif

Thanks anyway to everyone who contributed to this thread!

I'm sorry to confirm your bad news and be somewhat of an "I told you so", but this is exactly why a few posts back I said no one should ever use the onboard ICH10R for anything beyond raid-0. If you were on a hardware raid card you would of been able to recover everything no problem, most likely.

Well, this was all a bit of my fault, actually, as I didn't pay attention and change the BIOS settings back to what they should be... But I understand you... I just went a bit suspicious about RAID cards (at least without a proper RAID CPU), because of the problems I had with a RocketRAID. Granted, I only had problems after some 6 or 7 years using it, but still, lost a ton of stuff...

Anyways I'm seriously considering getting a RAID5, 4 slots QNAP for this storage, at least the probability of things going wrong should be lower, I guess smile.gif
