Red Hat

Anyone know of a way to get a FS to mount after a reiserfsck --rebuild-tree has failed on it? I am running Linux 5.2. I have read a bit about ddrescue, not sure if it can be run with a raid 10.

If your file system has failed, you are likely going to lose a good deal of data. However, you can bring the array into a degraded state by marking the bad drive(s) as failed and rerunning the fsck.

If I mark the drives as bad then can I mount the filesystem? Will it just be missing the degraded drives data?

Thanks

if you are using RAID 10, you should, in theory, have all your data. If you are doing RAID 10 in software, then you may have a bad drive. RAID 10 is essentially a stripe of mirrors. You should have at least 1 mirror of good data. How many drives are part of this array?

does smartctl tell you anything?

Also, you are not running "Linux 5.2" You are running some flavor of "Linux 2.6" However you may be running Red Hat Enterprise Linux 5.2 or CentOS 5.2. There's a difference, just so you know.

It may also be possible the drives are fine and the data is corrupted...
