EXT3 problems in Enterprise Workstation 3?

[Michael Halligan]

The kernel version is 2.4.21-9.0.3-SMP

And the boxes are almost identical in configuration. The only really
reproducable part of this problem is that it happens during periods of 
High disk activity, when I'm doing the nightly backups.  There are no
Large files though, these are small application and database servers.

This sounds like a major bug in at least the RedHat-shipped kernels. In
many older versions of Netbackup, files greater than 2GB could not be
backed up (I believe you'd get an Error 1, and the file would be
skipped). This should never cause massive filesystem corruption, and
Netbackup shouldn't be at issue here (it's just Veritas tar, and only
should change metadata when performing backups). Michael, do you have
your systems configured similarly? Marvin and Michael - what kernel
version are you running?

We are using veritas backup and we use ext3 for all filesystems.
Our backups would die at about the same place.  The last file 
Being backed up appeared to be a file that warnings would be generated
on.

I have the filesize limit set to 2 gb, and this file would appear to
Hit the limit.  Veritas would complain that it could not back this file
up.
We put in a script that cleans the file every night and have not had the
problem since.

I did not replace the disks as there was not enough evidence to show
that it
was the problem
