So, you should use either a group, or a colocation set, but not both with the same members. If you simply want to reorder the sequence in which the group members start, just recreate the group, listing them in the order you want. That If you're using pcs, you can change the order of resources within an existing group with the "pcs resource group add" command and --before or --after options. For example pcs resource group add your_group IP1 --after IP changes your group like this IP IP1 mount smb is, the first member of the group will be started first, then the second member, etc. If you prefer using sets, then don't group the resources -- use separate colocation and ordering constraints with the sets, as desired. ___ Users mailing list: Users@clusterlabs.org http://lists.clusterlabs.org/mailman/listinfo/users Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://bugs.clusterlabs.org ___ Users mailing list: Users@clusterlabs.org http://lists.clusterlabs.org/mailman/listinfo/users Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://bugs.clusterlabs.org

[ClusterLabs] resource group vs colocation
hi everyone I have a group and I'm trying to colocate - sounds strange - order with the group is not how I want it. I was hoping that with colocation set I can reorder the resources - can I? Because .. something, or my is not getting there. I have within a group: IP mount smb IP1 and I colocated sets: set IP IP1 sequential=false set mount smb and yet smb would not start on IP1. I see resource are still being order as they list.
