Nothing's wrong with the shell syntax here. I believe that this has been discussed before. When in doubt what the shell does, just use "show xml". > 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. Resource sets are not an issue in order constraints, but rather in collocations.
