I've got the storage and VM live migration sorted, but having trouble with pacemaker. I tried unmanaging the resource (the VM), then deleted the resource, and the node got fenced. So I am assuming it thought it couldn't stop the service so it self-fenced. In any case, can someone let me know what the proper procedure is? Said more directly; How to I delete a resource from pacemaker (via pcs on EL8) without stopping the resource?Set the stop-orphan-resources cluster property to false (at least while you move it) The problem with your first approach is that once you remove the resource configuration, which includes the is-managed setting, Pacemaker no longer knows the resource is unmanaged. And even if you set it via resource defaults or something, eventually you have to set it back, at which point Pacemaker will still have the same response.Follow up;
I tried to do the following sequence;
====
pcs property set stop-orphan-resources=false
pcs resource unmanage srv01-cs8 # Without this, the resource was stopped
pcs resource delete srv01-cs8 # Failed with "Warning: 'srv01-cs8' is unmanaged"
pcs resource delete srv01-cs8 --force # Got 'Deleting Resource - srv01-cs8'
pcs resource status
--
* srv01-cs8 (ocf::alteeve:server): ORPHANED Started an-a01n01 (unmanaged)

====So it seems like this doesn't delete the resource. Can I get some insight on how to actually delete this resource without disabling the VM?
Thanks!
Adding;
I tried 'pcs property set
stop-orphan-resources=true' and it stopped the VM and
then actually deleted the resource. =/
