Re: [linux-lvm] Mirrored LVs

Specify ranges of physical extents at the end of the command line
along with --alloc anywhere to get the layout of your choosing.

e.g. lvcreate ... /dev/sdb:0-2000  /dev/sdc:0-2000  /dev/sdd:0

(Sometimes you need to force a single-extent gap to make it
do what you want, so sdb:0 sdb:2-2000 ...)
