LVM Mirror Strict allocation

1. Use the strict allocation policy for all mirrored logical volumes. Strict allocation forces mirrors to occupy different disks. Without strict allocation, you can have multiple mirror copies on the same disk; if that disk fails, you will lose all your copies. To control the allocation policy, use the –s option with the lvcreate and lvchange commands. By default, strict allocation is enabled.
