Hello Kai, we use RBD's as part of pacemaker resource groups for 2 years on Hammer with no problems. The resource is always configured in active/passive mode due to the fact that the filesystem is not cluster aware. Therefore during switchover the RBD's are unmapped cleanly on the active node before the resource moves. Regards Steffen >>> Kai Wagner <kwagner@xxxxxxxx> schrieb am Dienstag, 6.
