I need my cluster has a master role which provides special services. As long as members are in same partition as master, the partition has the quorum regardless majority. Only if master down, re-election start and take over the special service by new master. My rough idea is make a quorum device and race quorum device at every begining, who holds the quorum device, it's master and cluster partition that includes master is quorate. If I build pacemaker on the top of heartbeat, I plan to modify CCM a little to achieve such kind of quorum algorithm. At same time, I need a way to tell pacemaker the speciality so that pacemaker can run special resource on the master node. Do you have any better idea?
