I just noticed this also:
[root@beethoven /root]# raidadd -a
[root@beethoven /root]# raidrun -a
[root@beethoven /root]# cat /proc/mdstat
Personalities : [2 raid0] [4 raid5]
read_ahead 128 sectors
md0 : active raid0 sdd1 sde1 sdf1 sdg1 sdh1 44419520 blocks 16k chunks
md1 : inactive
md2 : inactive
md3 : inactive
[root@beethoven /root]# lsmod
Module Size Used by
raid0 1656 1 (autoclean)
raid5 14660 0 (unused)
3c59x 17732 1 (autoclean)
It is loading it as a raid0 device, even though my raidtab says raid5!
