Hi Digimer, just to be clear: we have already cLVM because i'd like to store the vm's in plain logical volumes, without fs. That's running already. If i want live migration of vm's which resides on the plain logical volumes in conjunction with DRBD (DRBD on top of the lv ?) i don't need a cluster fs ? Thanks for the clarification.
