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.
