Debian RAID 1 Array Crashed; Trying to mount Disk 2
I am a freelancer just brought in today on this problem and I'm stumped.
My client had their email server running on a Debian install with software Raid 1 across two identical 40 gig Maxtor IDE hard drives. The OS was on disk 1, and disk 2 was used as the mirror.
The other day disk 1 failed. Disk 2 has no boot sector it seems, or is unmountable for some other reason. It won't boot from disk 2, anyways, and I was unable to mount it. Fsck says "DriveReady SeekComplete Error" and that it cannot read sector 0 (I ran "fsck /dev/hdb") and it acts as if there is no /hdb1, 2 etc.
I understand that Raid 1 is disk mirroring - is the data on disk 2? Can it possibly be accessed? If so, how?
Thanks for any help!
Debian Software Raid 1 Troubles
What I did was I connected it as a slave drive in a Red Hat 9 box I had, and tried to mount the drive normally, but I got the error messages as related in my first post, the drive wouldn't mount (I used "mount -t /dev/hdb (etc.) /<mount directory> and it would say "read error sector 0" or something like that.)
Perhaps I just don't know what the specification should be for the partition number, but I used hdb, hdb1, 2, 3, 4, etc. Tried up to seven.
This is software RAID 1 that apparently came with a Debian distro the previous (now long gone) admin had set up, perhaps he set it up incorrectly?
Any help greatly appreciated, thanks,
