When I rebooted my system (RHEL 5.3 x86_64), I got the following error when it was booting up:
Mounting root filesystem.
EXT3-fs Error (device dm-0): ext3_check_descriptors: Block bitmap for group 3328 not in group (block 33188)!
EXT3-fs: group descriptors corrupted!
mount: error mounting /dev/root on /sysroot as ext3: invalid argument
Full screenshot of the bootup error messages here: previous bootup error
So to try and fix this, I booted from the OS disk and did a linux rescue.
Here's some of the results of the commands I did:
sh-3.2# lvm lvchange -ay /dev/VolGroup00/LogVol00
sh-3.2# lvm lvscan
ACTIVE '/dev/VolGroup00/LogVol00/' [1.36 TB] inherit
inactive '/dev/VolGroup00/LogVol01/' [1.94 GB] inherit
sh-3.2# fsck -yfv /dev/VolGroup00/LogVol00
FYI: / is mounted on LogVol00, swap is LogVol01.
Here's a screenshot of the output from fsck after it's done, notice it says 0 bad blocks but the system was modified:fsck results
I then reboot but now I get the errors:
Setting up new root fs
no fstab.sys, mounting internal defaults
INIT: No inittab file found
Full screenshot of the startup errors I get now here: current bootup error
Does anyone have any ideas on how I can fix this? Was the fsck I did initially the correct thing to do to fix that initial group descriptor error or did I make things worse? I really need to get this system up so any help would be appreciated. Thanks!
