Wow! :-(

So that means that the FC5 system is not actually on RAID? Even though 
it seems so? (using /dev/dm-* for filesystem volumes)

# lspci | grep -i sata
03:05.0 RAID bus controller: Silicon Image, Inc. SiI 3114 
[SATALink/SATARaid] Serial ATA Controller (rev 02)
# df -m

So in fact /dev/dm-* are just on one disk each (not RAID1), or what is 
going on here?
