On a node in an asymmetric cluster where ceph isn't configured, the RA just wants to know that it isn't running - it won't like an error being returned. For a node without even the RA script installed it would return not-installed, but I think that's okay too. Do you think maybe the 'ceph status' check and the RA check have conflicting requirements here? Maybe it would be better to leave the init.d script as-is and build the smarts into the RA script instead. Do idle mds's add any load to the system? Would it be useful to be able to have pacemaker bring up mds's on any two nodes so you always have exactly two running, without actually tying them to specific nodes?
