The usual problem with LVM on top of DRBD is that the backing device
gets seen as an LVM PV and is grabbed by LVM before DRBD starts up.
That means DRBD cannot access it since it's already in use.
Solution: adjust the filter lines in lvm.conf to exclude the backing
devices from LVM consideration.<br>
