I was setting up a new server (6.1 i386 STABLE) - more specifically, I

GEOM_MIRROR: Request failed (error=5). ad0[READ(offset=313192349696,
length=131072)]
Along with several more errors, which were very similar. At this point,
the server pretty much froze and would repeat the error at reboot, and
as gmirror began resyncing the drive, the server would crash. I've tried
disabling the mirror, fscking (multiple times), removing disks, and I
just got done reinstalling (which went just fine) and resyncing. I still
get the error and the system becomes unusable.
So, my question is - and I suspect this is the case - is this a drive
failure or some issue with the mirroring process?
It *is* a drive failure, but I don't understand all of what's
happening there. It is possible that this is not a FATAL drive
failure, but it's hard to be certain from this information. If you
can figure out which file contains the bad sector, you can rewrite
that file and the drive may be able to recover.
Thanks for your reply. After messing with it some more, I decided to
just send the drive back and see if I have better luck with the
replacement. The sector that was damaged was on an almost-empty
portion of the disk, which was a bit strange to me. *shrugs*
Thanks again,
Jason Morgan
