The first time, I did RAID0 first and then combined them into RAID1. Did
not work. After a reboot, the mirrored stripe array disappeared.
The second time, I did RAID1 and combined them into RAID0. After reboot,
the same thing happened, the striped mirror disappeared.
How can I ever create a RAID10? I'm giving myself one more day to make
this work. After that, it's RAID5 for me. Please help anyone...
