Hi all,

I have a Postgres HA with DRBD, Corosync, Pacemaker.

It worked perfect when I disconnected network card of node 1, or standby 
node1, node2.

But when I shutdown node1, node2 did not bring the resources up. There 
was a message:

     "block drbd0: PingAck did not arrive in time."

Here is crm_mon log:

Online: [ node2 ]
OFFLINE: [ node1 ]

  Clone Set: fencing_pg [stonith_pg]
      Started: [ node2 ]
      Stopped: [ stonith_pg:1 ]
  Master/Slave Set: ms_drbd_pg [drbd_pg]
      Slaves: [ node2 ]
      Stopped: [ drbd_pg:0 ]
  Clone Set: cl_ping [ping]
      Started: [ node2 ]
      Stopped: [ ping:1 ]

Here is my configuration:

         attributes standby="off"
