Ah ha....

# ls -l /sys/block/*/holders/*
lrwxrwxrwx 1 root root 0 Feb 26 06:28 /sys/block/sdb/holders/dm-0 -> 
../../../block/dm-0
lrwxrwxrwx 1 root root 0 Feb 26 06:28 /sys/block/sdc/holders/dm-0 -> 
../../../block/dm-0

which I am assuming is dmraid? I did a quick check, and

# dmraid -r
No RAID disks

Doesn't look like there is anything defined.  I know that both sdb and sdc (as 
well as sda) are connected to SATA cards which support RAID under windows... 
However, I know there is no arrays defined on them on the cards (at least not 
by me)... I will bounce the server again and check.
