I have excluded /dev/sdb2 in the lvm.conf file thus: filter = [ "r/dev/sdb2" ] This is the output from pvcreate and pvdisplay. I feel that i have left out some vital step somewhere here??: server1:/etc/lvm# pvcreate /dev/drbd0 -vvv Processing: pvcreate /dev/drbd0 -vvv O_DIRECT will be used Setting global/locking_type to 1 Setting global/locking_dir to /var/lock/lvm File-based locking enabled.
