Whoops - I was mistaken (I assumed! - changed both ordering and colocations and didn't try each independently first!)...
It is the colocation constraint that is the problem not the ordering. Here is those statements: colocation c_lsb_arpwatch_on_fs_arpwatch_on_drbd_arpwatch_master inf: p_lsb_arpwatch p_fs_arpwatch ms_drbd_arpwatch:Master Stop stops both lsb and fs colocation c_fs_arpwatch_on_drbd_arpwatch_master inf: p_fs_arpwatch ms_drbd_arpwatch:Master colocation c_lsb_arpwatch_on_fs_arpwatch inf: p_lsb_arpwatch p_fs_arpwatch Stop stops only lsb. Same questions though... something wrong with my statement logic or a bug?
