Hi,
i had that problem already once but still it's not clear for me what really
happens.
I had this problem some days ago:
I have a 2-node cluster with several virtual domains as resources. I put one
node (ha-idg-2) into standby, and two running virtual domains were migrated to
the other node
Right, so I may have been too fast to give up. I set maintenance mode back
on and promoted ph-sql-04 manually. Unfortunately I don't have the logs of
ph-sql-03 anymore because I reinitialized it.
You mention that demote timeout should be start timeout + stop timeout.
Start/stop are 60s, so that
I've crossposted the question about checkpoints taking a long time to
pgsql-general as well :)

In fact, the action that timed out was the demote action, not
Current size of the database is around 600GB uncompressed (LZ4 compression

Hi, yes I'm also puzzled by this. The cluster is certainly not
underpowered, running on baremetal with 8x SSD in ZFS stripe of mirrors,
128 GB RAM and shared_buffers is set to 8GB.

That's surprising checkpoint took longer than 60s. What is the size of your
shared_buffers? What kind of hardware do you use (baremetal,

Hello,
I setup a new 3-node PostgreSQL cluster with HA managed by PAF. Nodes are
named ph-sql-03, ph-sql-04, ph-sql-05. Archive mode is on and writing
archive files to an NFS share that's mounted on all nodes using pgBackRest.
What I did:
- Create a pacemaker cluster, cib.xml is attached.
- Set
