Re: [Pacemaker] Pacemaker remote nodes, naming, and attributes

Well, I'm not getting failures right now simply with attributes, but I can induce a failure by stopping the vm-db02 (it puts db02 into an unclean state, and attempts to migrate the unrelated vm-compute-test). I've collected the commands from my latest interactions, a crm_report, and a gdb tracebac

[Pacemaker] Monitor and standby

Hi List, we have a two node cluster (test1-node1, test1-node2) with an additional quorum node (test1). On all nodes MySQL is running. test1-node1 and test1-node2 sharing the MySQL-Database via DRBD, so only one Node should run MySQL. On test1 there is a MySQL-Slave connected to test1-node1/test1-n
