I would suggest setting a collocation constraint between both master resource. Something like this: pcs constraint colocation add master pgsql-ha with master clusterfs-clone INFINITY pcs constraint order promote clusterfs-clone then promote pgsql-ha kind=Mandatory I have no suggestion for GFS setup though. BTW, why are you using a shared storage between your pgsql node?
