Hello all,
I just installed a new beta kernel from Dzickus over at redhat. Rebooting causes this, no matter what kernel I boot from:
EXT3-fs error: device dm-0: ext3_check_descriptors: Block bitmap for group 5008 not in group (block 167772160)! EXT3-fs: group dexcriptors corrupted! Mount: error mounting /dev/root on /sysroot as ext3: Invalid argument
Setuproot: /moving /dev failed: no such file or directory
And a bunch of other mounting errors. OK, so, I have a Centos 5.2 install disk, but what can I do to get everything back?
Any help greatly appreciated. Thanks!
Gilbert

Try rescue mode?

Be prepared to restore from a backup too, doesn't look good.
Also I'd suggest running manufacturer diagnostics on your disk(s).

No need to...Seagate screws me again. 3rd bad hard drive on this server. Unbelievable. Under warranty, but...grrrr.

I heard something about the 1.5TB Seagate drives having bugs that would cause data corruption, and that it could be fixed by doing a firmware upgrade, which can be accomplished with a tool downloaded from their website... It's second hand information, but maybe check their website and google for your exact model to see if there is something wrong with it...

you're right, there was a firmware bug and Seagate has a diagnostic program to check whether your drive is affected and an update patch to fix it. Not only that but if the drive is bricked they are [were] offering data recovery.

One tip I try to adhere to, although hard to follow when setting up a new computer is this...
Try to get drives from different manufacturing batches. Buy from different online stores, talk to the cust service of places like newegg, etc...
If you buy a drive that was part of a bad batch the drive may still survive. The likely hood of it having an issue is high though. If that batch has problems there is high probablility all your drives in that batch can go bad.
Hard to take the time, but seems worth it. If one fails, all can fail if from the same batch. Lessen odds, buy different batches.

That is probably excellent advice, if one does not need identical drives, for RAID or something. Several times, in the past 7 1/2 years, on the OLM support site, I've seen where a server is down because of multiple drive failures.
