[ClusterLabs] Antw: [EXT] delaying start of a resource

[Gabriele Bulfon]

Thanks, here are the logs, there are infos about how it tried to start resources on the nodes.
Keep in mind the node1 was already running the resources, and I simulated a problem by turning down the ha interface.

AFAIK pacemaker will not start resources on a node that is scheduled for stonith. Even more: Pacemaker will tra to stop resources on a node scheduled for stonith to start them elsewhere.

We probably need to see logs and configs to understand.

I think it's on by default, so you must have set it to false.
In crm shell it is "configure# property stonith-enabled=...".
