Hi !
I've got a Linux server with failed 2-disk software RAID (and valuable data). fsck.ext3 tries to check it on startup but fails with "Unrecovered Read Error - Auto reallocate failed" errors. Looks like some blocks gone bad.
fstab entries looks reads:
/dev/md0 /home ext3 acl, user_xattrs /dev/sda1 /data2 ext3 defaults 1 1 /dev/sda2 /data3 ext3 defaults 1 1
First of all, I could not figure out - is this software RAID 0 or RAID 1 (it is not mountable so I cannot figure out MD0 refers to RAID device number not to its level)? if this is RAID 1 I can simply remove HDs one by one and eliminate one with bad blocks.
Yes, If it is indeed software raid, you can simply unpower one of the drives and see if you can mount the other directly. If so, recover data, and rebuild. If not, try the other drive. If its raid0 you have bigger problems, about the same problems is you had used LVM and skipped raid all together, but even given the lack of redundancy, LVM makes more sense than raid0 in linux. So I'm guessing no sane person would use raid0 just to concatenate drives in linux, and you probably don't have raid0. -- ----------JSA--------- Sig line deleted for the humor impaired. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
