Comment 2 for bug 1744141

Yes you are right.. the cluster was 2 nodes, when I removed the master unit it goes to failover the secondary and raised it to master.

After a while I added 2 lxd nodes, and after they are started as secondary successfully ... I do removed the master, but unfortunately it couldn't failover.

and they are still waiting the master "pgsql-ha/7" to failover from... however it is gone!

Unit Workload Agent Machine Public address Ports Message
pgsql-ha/10 waiting idle 4/lxd/1 x.x.x.41 5432/tcp Failover from pgsql-ha/7
pgsql-ha/11* error idle 4/lxd/2 x.x.x.40 5432/tcp hook failed: "replication-relation-changed"

I'm attaching the related logs.
