If it was not possible to mount the filesystem then how/why did the cluster try to unmount it? Also, if the filesystem's not mounted then the stop operation should've succeeded. Or did you see different behaviour? > Start and Stop of the Filesystem always ended up with a Timeout > (of 120 s). > > How can we treat that issue within HA? What happens with a resource > which can not run anymore? When will HA give up to run it? Depends on the start-failure-is-fatal crm_config parameter. If it's set to true, the CRM should give up after the first failed start operation. Of course, in case the machine is rebooted it will try again. > My understanding is that default resource failover stickiness will not > help us in such situation because the failcount gets reset due to node > reset. > > We will configure auto_failback off with setting a high value for > default resource stickiness.

If a set of resources must run on one node but there are no other dependencies, then use an unordered group. Any news?
