Re: [Linux-HA] FW: Can't seem to shutdown the DC
Thanks Lars, support request is 10855509041. I improved the situation a bit by added a dc-deadline of 2min, but it still won't shutdown correctly (the other nodes still think it is online). Also upgraded it to SP3 with no change in results.

Re: [Linux-HA] Clone colocation missing? (was: Pacemaker 1.19 cannot manage more than 127 resources)
Hi Feri I agree that it should be necessary but for some reason it works well the way it is and everything starts in the correct order. Maybe someone on the dev list can explain a little bit better why this is working. It may have something to do with the fact that it's a clone instead of a primitive.

Hi, Sorry to sidetrack this thread, but I really wonder why you only have order constraints for your Xen resources, without any colocation constraints. After all, they can only start after the *local* storage clone has started... For example, you have this: primitive abrazotedb ocf:heartbeat:Xen [...] order abrazotedb-after-storage-clone : storage-clone abrazotedb and I miss (besides the already mentioned inf above) something like: colocation abrazotedb-with-storage-clone inf: abratozedb storage-clone Or is this really unnecessary for some reason?

[Linux-HA] Xen RA and rebooting
Hello All Does anyone know of a good way to prevent pacemaker from declaring a vm dead if it's rebooted from inside the vm. It seems to be detecting the vm as stopped for the brief moment between shutting down and starting up. Often this causes the cluster to have two copies of the same vm if the locks are not set properly (which I have found to be unreliable) one that is managed and one that is abandonded. If anyone has any suggestions or parameters that I should be tweaking that would be appreciated.
