Really?  Oh that just may start something.  I could easily setup two
drives and use LVM on them.  I just didn't know that it would work.  One
added benefit, they are encrypted with cryptsetup which puts everything
on top of LVM.  So, the data isn't available until I type in the
password and then mount it.  It doesn't try to mount automatically or
anything because of that.  Oh, this could be the start of something.
