I would recommend breaking this into "basic" constraints. The shell syntax for constraint sets has been a source of confusion for a while. order o1 inf: ms_drbd_postgres:promote postgres:start order o2 inf: postgres:start ms_toponet:start order o3 inf: ms_toponet:start ms_toponet:promote order o4 inf: ms_toponet:promote monitor_cluster:start If you still have problems with the expanded form, let us know. > > I want to the pacemaker to act as in 1.0.12 version. > * when toponet master app is killed, move postgres resource to other node > and promote ms_toponet and ms_drbd_postgres to Master > * when one node is starting promote DRBD to master is is UpToDate > > Am I doing something wrong? > > It looks to me pacemaker ignores some orders (pacemaker should wait for DRBD > promotion when starting toponet app, but toponet app is started right after > DRBD start (slave)).
