journal aborting and remounting /boot as ro



Hi,

My /boot filesystem is being remounted as read-only. I'm not sure what triggers
it, I've seen the messages below waiting for me at the login prompt in the
morning and they've also popped up as I was fiddling around in /boot trying to
figure out what was wrong.

I get the following messages...

journal_bmap_Ra7a5f568: journal block not found at offset 12 on ide0(3,1)
Aborting journal on device ide0(3,1)

ext3_abort called
EXT3_fs abort (device ide0(3,1): ext3_journal_start: Detected aborted journal
Remounting filesystem read-only

Any ideas how I can fix this? My fstab looks like this...

LABEL=/		/			ext3		defaults						1 1
LABEL=/boot	/boot		ext3		defaults						1 2
none				/dev/pts		devpts	gid=5,mode=620	 			0 0
none				/proc		proc		defaults						0 0
none				/dev/shm		tmpfs	defaults						0 0
/dev/hda3		swap		swap	defaults						0 0
/dev/cdrom		/mnt/cdrom	iso9660	noauto,user,kudzu,ro			0 0
/dev/hdd4		/mnt/zip		auto		noauto,user,kudzu,rw			0 0
/dev/fd0			/mnt/floppy	auto		noauto,user,kudzu,rw			0 0
remhost1:/users/	/users		nfs		noauto,user,exec,dev,rw,hard,intr	0 0
#/dev/hdb1		/dosc		ntfs		ro,umask=000					0 0
/dev/hdb2		/dosd		vfat		ro,umask=000					0 0
abc:/export/home/	/tof			nfs		noauto,user,exec,dev,rw			0 0

I'm running RH 7.3, installed from rpms so I haven't done any configuration of ext3, 
and haven't been able to find any documentation on how to.

I discovered the problem when trying to upgrade the kernel which, obviously, can't
be done with /boot mounted read-only. Curiously, I was able to use up2date to upgrade 
to kernel-2.4.18-5 recently without this problem occuring. Otherwise, I haven't noticed
any effects.

Any advice much appreciated,

John O'Brien.
