rebuild the journal on an ext3 partition for CentOS 5.3

Posted on Sat Jan 16 15:22:00 UTC 2010

Heltech does not have it quite right for centos. The options are named slightly differently on newer versions.

Here’s the correct sequence for CentOS 5.3

  • Boot in single mode
  • umount the main partition
  • check the partition for errors
  • remove the journal
  • remount
  • recreate the journal
  • for good measure, check the partition for errors
or, in other words: 
# fsck /dev/VolGroup00/LogVol00
# umount /dev/VolGroup00/LogVol00
# tune2fs -O ^has_journal /dev/VolGroup00/LogVol00
# mount -n -o remount,rw /dev/VolGroup00/LogVol00
# tune2fs -j /dev/VolGroup00/LogVol00
# umount /dev/VolGroup00/LogVol00
# fsck -f /dev/VolGroup00/LogVol00

Note: this should also work on CentOS 5.4
