filesystem mount in Read only mode.

I am using RHEL AS4 .Intermittently "JOURNAL ABORTED: REMOUNTING FILESYSTEM READ ONLY" error comes but after reboot the server is working fine .
I checked with the hardware, it is fine.
Please help me to solve this issue.
And also i suspect EXT3 patching may solve this issue , if so where can i get this patch.
Thanks in advance

Seems your filesystem was corrupt.
After server restart, fsck is called automatically (by using /etc/rc.d/rc.sysinit script) and your filesystem was restored again.
It could be just a one-off event that corrupted it.

Thanks for your reply.
This has happened thrice, since it is a production server, i cannot afford to reboot again & again.

1st of all, get a backup of your system.

I see journal aborts quite often when I'm doing stress testing of systems. I've never seen it remount to read-only, but I'm not really surprised.

The fix for me is four-fold:

1) make sure that the SCSI card drivers and firmware are up to date

2) make sure the cabling is in good shape

3) make sure that the drive firmware is up to date

4) make sure you aren't putting too much load against the drive.
