FSCK of corrupted ext3 filesystem



Hello,
I have a 1.3TB ext3 filesystem that has been in service for about 3 months.
About 6 days ago the Emulex fibrechannel controller logged a SCSI error and the filesystem changed to RO.
It appears that the filesystem instantly changes to RO and prevents the journal from working, therefore invalidating the filesystem.
The filesystem was unmounted and a remount was attempted. The mount failed due to errors and an fsck came up with errors.


Top output looks like this:

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
4562 root 25 0 780m 214m 236 R 99.9 42.6 6211:44 fsck.ext3


The fsck has been running for 6 days without printing anything to the screen. It seems to be working as an strace produces the following.

Process 4562 attached - interrupt to quit

Process 4562 detached


How long should I let the fsck run?
