journal corrupted on / filesystem

[Jordi Prats]

Hi,
Yes it did not work on a live system, you need to reboot it, after the 
procedure you must reboot.

For the record what I did was:

Mark the filesystem as it does not have a journal (take it to ext2)

tune2fs -O ^has_journal /dev/cciss/c0d0p2

fsck it to delete the journal:

e2fsck /dev/cciss/c0d0p2

Create the journal (take it back to ext3)

tune2fs -j /dev/cciss/c0d0p2

and finaly, remount it. On a live system, just reboot it.

Thank you all,
Jordi
