>Description:
raidframe level 1 with more than 2 components are not supported, as explained 
in raidctl(8) man page. However, raidctl(8) will not complain when one attempts 
to confiture an unsupported setup such as this one:

START array
1 4 0
 
START disks
/dev/wd0a
/dev/wd1a
/dev/wd2a
/dev/wd3a
 
START layout
32 1 1 1
 
START queue
fifo 100

raidctl should complain about the unsupported setup, and suggest to do a RAID 
of RAID to acheive the goal.
