I have a FreeBSD 6.2-based server running a 1.2TB graid3 volume, which
consists of 5x 320gb SATA hard drives. I've been getting errors in
/var/log/messages from the graid3 volume, which I suspect means an
underlying fault with one of the disks, but is there any way to decipher
which one of these drives is throwing errors?
I've checked smartctl -a /dev/adXX but nothing shows up there.. I'm
wondering if this is the infamous ata driver bug(s) that may be rearing
its ugly head..
Also, does anyone know what "ZoneXXFailed" items in the graid3 list
output mean?
Relevant output:
