EXT3 problems in Enterprise Workstation 3?

[Michael Halligan]

Our ext3 mount options : 

LABEL=/  / ext3 defaults 1 1

Nothing really special.

We have had two or three bad raid cards, and a couple of failed
motherboards out of about 30-35 servers we've ordered in the past 6
months.. I'm starting to lean towards hardware, because I think I have
another two failed motherboards (thanks dell), but I can't find any
evidence to point towards hardware right now.

In terms of disks, I've done bad block checks with fsck, returning no
errors, and I've done consistency checks on the PERC card, also finding
no problems.

For backups I'm using Rsnapshot (http://www.rsnapshot.org) .. It's
basically just rsync doing incremental backups.

What are you using to perform backups? We're running PowerEdge 1750s,
2650s, and 6650s using RHEL 3 ES rather than WS, and have not seen this
issue using Veritas NetBackup. Are you using any ext3 options on root?
It sounds like you're experiencing a batch of bad RAID cards (or as
Marvin indicated, maybe a bad batch of disks?)

We have had some strange problems during backups also.
The file system starts reporting errors and the system hangs.  
A reboot fixes this.

We have had this problem on 2 dell 2650's.  There answer was to replace 
All the disks in the system with another make.

They really don't have a clue as to what is happening.
