You may encounter problems with journal in file system. It means that, your system will boot normally as it should. But after sometime, the partitions will be remounted as Read-Only file system since kernel is unable to read the blocks int the journal. In this situation, we used to try fixing with a manual file system check. But it solves the problems in a rare case. So, the only way to fix this issue by rebuilding the journal. This can be achieved using the following steps.
Note : Please make sure that you have booted the machine with a Rescue CD or through Single User Mode.
Consider, the partition /dev/sda5 is having corrupted journals,
Un-mount the partition
umount /dev/sda5
Perform a FSCK
f sck -y /dev/sda5
Remove the journal support
tune2fs -O ^has_journal /dev/sda5
Perform fsck again
fsck -y /dev/sda5
Covert to ext3 (or) Enable journal
tune2fs -j /dev/sda5
After executing the above command, remount the partition (or) reboot the system/server.
Try this out...
