Hallo, On a cluster I have to place three resources on the same node.
ms ms_disk_R p_disk_R ms ms_disk_S p_disk_S primitive vm_srv ocf:heartbeat:VirtualDomain The colocation constraints looks like this: colocation vm_with_disk_R inf: vm_srv ms_disk_R:Master colocation vm_with_disk_S inf: vm_srv ms_disk_S:Master Do I have to add another colocation constraint to define a colocation between disk_R and disk_S. I'm not sure because the documentation says: "with-rsc: The colocation target. The cluster will decide where to put this resource first and then decide where to put the resource in the rsc field." In my case the colocation targets are "ms_disk_R" and "ms_disk_S". If pacemaker decides to put disk_R on node A and disk_S on node B vm_srv would not start. I use order constraints to start disks before the vm resource. order disk_R_before_vm inf: ms_disk_R:promote vm_srv:start order disk_S_before_vm inf: ms_disk_S:promote vm_srv:start Thanks Matthias _______________________________________________ Pacemaker mailing list: Pacemaker@oss.clusterlabs.org http://oss.clusterlabs.org/mailman/listinfo/pacemaker Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://bugs.clusterlabs.org
