does it momentarily offline the disks? like they re-appear in /dev
within moments? That would be similar behavior to what I am
experiencing, the disks drop from the array, but they are in /dev by the
time I get a chance to see them.

I am however not running smard to my knowledge, smartmontools is
installed and I access it through the webmin module, but checking the
drives with that and the array failures have not happened at the same time.

This is interesting to hear as I have been using smartmontools on my
Supermicro LSI 1068E controller with the target firmware for 2 years
now on CentOS 5. I have 3 RAID 1 arrays across 2 drives, a RAID 5
drive across 3 drives, and a RAID 0 across 2 drives.

Kernel version matters. With 2.6.22 we only got occassional complaints
that the drives are not capable of SMART checks that were not true but
were otherwise harmless. With 2.6.26 and 2.6.30, the controller offlines
the disks.
