RE: ext3_get_inode_loc: bad inode number:



I have recently done some testing on ext3 fs for large file systems  ( > 1
TB )
and ext3 has shown no problems as such .

One thing I can assure you that the size has nothing to play any role in
your problem .

Subject: ext3_get_inode_loc: bad inode number:



	I've got an approximately 100GB ext3 FS which we recently sized down
from 300GB using e2fsadm (with the disc offline obviously). I noticed the
following in dmesg the other day:

	I took this disc offline and ran fsck twice. It found a few errors
the first time and none the second. I then rebooted the server, but the
errors returned. The obvious next step would seem to be to build a new
file-system and tar copy the data. Does it seem reasonable that the shrink
could have corrupted the inode table? There is a lot going on with this
setup (could be LVM, ext3online_resize, etc), so mostly I'm just curious if
it is reasonable that the shrink could have been responsible or if there is
some other component I should examine. Thoughts?

RedHat 7.2
kernel linux-2.4.19
	lvm-1.0.6
	ext3-2.4 + online_resize patch
e2fsprogs-1.28 w/ ext3resize 
ext2resize-1.1.18 (CVS actually)
RAID5 - 4 discs on SAN, qla2200 driver (6.04.00)

Thanks,
