Hi, I have an idea: use Pacemaker with Zookeeper (instead of Corosync). Is it possible? Is there any examination about that?
From my point of view (and yes, I'm biased), biggest problem of Zookeper is need to have quorum (https://zookeeper.apache.org/doc/trunk/zookeeperAdmin.html#sc_designing). Direct consequence is inability to tolerate one node failure in 2 node cluster -> no 2 node clusters (and such deployment is extremely popular). Also Corosync can operate completely without quorum.

Thanks for your help! Hai Nguyen
