[Pacemaker] Configuring 3rd Node as Quorum Node in 2 Node Cluster

[Andrew Martin]

I think I will configure the 3rd (quorum) node in standby mode. In the near future I am looking into setting up 2 additional clusters (each of these are also 2-node clusters) and would like to use this same server as the quorum node for those clusters as well. Is this possible? If so, how do I have to configure heartbeat (or multiple instances of heartbeat) to join multiple clusters at once and act as the quorum node in each? 


Thanks, 


Andrew

It would run no resources (including stonith resources) but can be the DC. 

Another option for running a "pure" quorum node would be to only start 
CCM but not pacemaker ... though that setup looks quite strange e.g. in 
crm_mon output ....
