rebuild the journal on an ext3 partition for CentOS 5.3

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
