EXT3 problems in Enterprise Workstation 3?

[Faehl, Chris]

Michael,

We've also seen our share of bad RAID cards, but most of those affected
external disk arrays. I would think (hope) that if this was a RAID
issue, you'd see all sorts of warnings at least via dmesg and hopefully
output to the console (is /var/log/messages on its own partition, or
part of /?) . We've purchased a similar number of 1750s in the same time
period, but haven't seen these issues (the 1650s seemed to have almost
constant problems, though). 

I suspect that Marvin's issue is toxic kernel (Marvin: since you're
using a variant of the 2.4.9 kernel, I'm assuming you're running RHEL
2.1), but I'm not sure about yours (yours sounds to be much more serious
than Marvin's issue, since you end up losing the whole filesystem
through subsequent fsck "fixes").

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.
