[olug] disk woes

[Phil Brutsche]

How old is the drive? It sounds like normal sector remapping, especially
one an older drive would do.

I would be worried about the uncorrectable errors, and would take them
as a sign that the drive will go pttth soonish.

Oh, and I've never seen these messages on any of my CentOS hosts, but I
don't run smartd on them either - all but one have hardware RAID cards
and therefore other methods of detecting bad hard drives.
