Hi  Folks,

  I am working on HA with 3-nodes, which has below configurations:

"""
pcs resource create ovndb_servers ocf:ovn:ovndb-servers \
  master_ip=168.254.101.2 \
  op monitor interval="10s" \
  op monitor interval="11s" role=Master
pcs resource master ovndb_servers-master ovndb_servers \
  meta notify="true" master-max="1" master-node-max="1" clone-max="3"
clone-node-max="1"
pcs resource create VirtualIP ocf:heartbeat:IPaddr2 ip=168.254.101.2 \
    op monitor interval=10s
pcs constraint order promote ovndb_servers-master then VirtualIP
pcs constraint colocation add VirtualIP with master ovndb_servers-master \
  score=INFINITY
"""
  However, after setting it as above, the master is not being selected, all
are stopped, from pacemaker log, node-1 has been chosen as the master, I am
confuse where is wrong, can anybody give a help, it would be very
appreciated.


 Master/Slave Set: ovndb_servers-master [ovndb_servers]
     Stopped: [ node-1.domain.tld node-2.domain.tld node-3.domain.tld ]
 VirtualIP (ocf::heartbeat:IPaddr2): Stopped
