[ClusterLabs] Preventing multiple resources from moving at the same time.

[Matthew Schumacher]

I have a resource that more or less makes or breaks everything (storage).

When I move it, it only takes a few seconds and everything keeps working 
due to timeouts, however, if another resource tries to migrate/move at 
the same time it will break and causes an outage.

Is there any way to define a resource group in such a way where if it's 
in the process of being moved, don't move anything else no matter what?

Thanks,
Matt
