I am running a zfs array in an HP N40L Microserver that has been 99.9% reliable over the past 3 years or so. Yesterday, I got an error resulting in data corruption, but the volume says it's still online, but "applications may be affected".

The first thing I did was a zpool status -v to see which file(s) were affected, and I got the following:

Code:
[root@nas2] /# zpool status -v
  pool: freenas-boot
 state: ONLINE
status: One or more devices has experienced an error resulting in data
  corruption.  Applications may be affected.
action: Restore the file in question if possible.  Otherwise restore the
  entire pool from backup.

I do not consider myself a FreeNAS, nor a BSD expert, so my ability to troubleshoot this is a little limited. From what I can tell, it looks like a single file (libaria2.a) on the flash drive is corrupt. The primary data volume on the server seems unaffected. It hosts roughly 10 VMs connected via iSCSI to small Xen cluster. All the VMs have been happily running, but I obviously want to fix the error.

Should I schedule some downtime and pull the thumb drive? Should I just plan on replacing it altogether? I have plenty laying around... but if I'm going to do that, I'll probably start looking for a no-kidding, know-for-reliability thumb drive. To be honest, the fact that it's been working perfectly for so long is pretty impressive to me. :)

Yes, it's a problem with your flash drive. Hopefully you have a backup of your configuration file.

Don't try to "fix" the current flash drive. Do a fresh install of 9.3 (whatever version you are on) on a name brand (Sandisk, etc.) and restore your configuration file.

You might also look into mirroring your flash drive so you have redundancy there also.

Thanks for the replies.

It has been a while since I backed up the config, however, I can still get into the webui, and everything *seems* to be running perfectly. Would it be safe to take a config backup now?

For now, yes.
