This is not enough, you will end up with a trashed system since node2 will still be writing data to the wrong place. I think you should consider only doing offline operations. ie, acquiring the lock should fail if any other nodes have activated the vg. If you really insist on doing live operations I suggest you look at the device-mapper driver (LVM2), which contains the suspend functionality that you will need. - Joe _______________________________________________ linux-lvm mailing list linux-lvm@sistina.com http://lists.sistina.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://www.sistina.com/lvm/Pages/howto.html
