Hmm.  I'll give that a try, but it's not the way the controler
configured it fyrom the BIOS utility.  It was definitely a mirror
of 2 6 disk stripes.  The controller is a Perc 6/E.

My playing has now left:

[nagios06.jnb1] ~ # mfiutil -u1 show volumes
mfi1 Volumes:
  Id     Size    Level   Stripe  State   Cache   Name
 mfid2 (  419G) RAID-1       1M OPTIMAL Enabled  <transaction log>
     0 (  837G) RAID-10      1M OPTIMAL Writes   <moooo-delete-me>

And I can't delete the '0' volume.
