Hi all,
Simple crm configure syntax question (I think). I'm trying to make a given role (a 'Master' in a master/slave set) from being location on a given node. However, the "obvious" syntax (at least in my mind) doesn't work:
location avoid_being_the_master ms_MySQL:Master -1000: my_node
location never_be_the_master ms_MySQL:Master -inf: my_node
This man page tells me I'm close: http://www.clusterlabs.org/doc/en-US/Pacemaker/1.1/html/Clusters_from_Scratch/ch06s07.html , I suspect it's the :Master rule that is screwing me up. How can I specify the Master role? The following colocation rule works fine:
colocation writer_vip_on_master inf: writer_vip ms_MySQL:Master
