I don't think that has anything to do with DRBD, (you'll see that when you try with some dummy resources instead). Just moving something "top of the dependency chain" won't move the bottom of the dependency chain, especially not a Master role. This is a Pacemaker shortcoming. You can have depending resources follow a Master role, but Pacemaker is not "smart enough" to recognize moving the Master role would help with starting the resources you moved to some other node. Workaround: move the master role, or something the master role depends on. -- : Lars Ellenberg : LINBIT | Keeping the Digital World Running : DRBD -- Heartbeat -- Corosync -- Pacemaker DRBD® and LINBIT® are registered trademarks of LINBIT __ please don't Cc me, but send to list -- I'm subscribed _______________________________________________ drbd-user mailing list [email protected] http://lists.linbit.com/mailman/listinfo/drbd-user
