Mirroring disk which is under LVM control

[Joe Hood]

Hmm, I created a disk mirror then formatted the resultant disk sets (2
sets of mirrored SATA drives) as LVM, I'm not having any problem.

And with SATA RAID, you'll discover most of the time that the RAID is
really software, not hardware (http://linux.yyz.us/sata/).
