Hey, I have just tried to start the repmgrd on the new standby after I have fixed it as a standby and still this goes the same way. from the message given in the repmgrd log in the witness server it seems that he is not able to elect a new master because he can't see anyone . I have check in the repl_nodes table in the witness and it shows: witness node3 master node2 master node1 is there a way update the witness after the first failover? 2015-08-13 15:06 GMT+03:00 Jony Cohen <jony.cohe...@gmail.com>: > Hi Aviel, > you can use the 'show cluster' command to see the repmgr state before you > do the 2nd failover - make sure the node1 is indeed marked as replica. > After a failover the Master doesn't automatically attach to the new master > - you need to point him as a slave (standby follow - if possible...) > did you start the repmgrd on node1 after making it a replica of the new > master?
