RAID 10...went bad and now rebuilding...how do I know what went wrong?
Posted on 2004-10-25
I have a computer with 4 hard drives in a RAID 10 configuration. 2 hard drives are striping and 2 are mirroring.
I came in today and the computer was making a constant beep sound, so I rebooted and got some message that the RAID was corrupt or something, but before I could write the message down the RAID started to rebuild itself.
I have a lot of very important data on this computer, and a program was running creating files when this happened, and I am concerned about both the integrity of those files as well as the situation of my 4 hard drives. The computer seems to be fine now. The RAID is still rebuilding itself.
1) How can I find out what happened? Is there a RAID log or something? I cannot find any RAID utility software in the computer.
2) How can I see that status of the drives? I went to Disk Management but it just shows one disk that is the size of the 2 striped HD's combined. I don't know if one of the hard drives has gone bad, and I can't find anywhere (like Disk Management or Device Manager) that actually lists all 4 hard drives.
FYI I am new to this RAID stuff so please be kind on terminology! A longer, rambling answer is preferred to a short one, as I have a lot to learn about managing this computer!
