This is from memory because I"m at home and the machine is at the
office. But it should be close enough.

# raidstart /dev/md0
raidstart: Invalid Argument

if I let the system auto-start it during boot, it looks like this:

Starting Raid Devices: /dev/md0
raidstart: Invalid Argument
/dev/md0 is not a RAID0 or LINEAR set
