Ken, Thank you very much for the response. That method does allow us to reload the configs, but it's a bit heavy-handed for our use case. All we're wanting to do is rotate the log files. Is there any other mechanism we could use to achieve that goal? Thanks! Mike On 6/9/20, 7:10 AM, "Users

It will be hard to guess if you are using sctp or udp/udpu. If possible share the corosync.conf (you can remove sensitive data, but make it meaningful). Are you using a firewall ? If yes check : 1. Node firewall is not blocking the communication on the specific interfaces 2. Verify

Hello, We have massive problems with the redundant ring operation of our Corosync / pacemaker 3 Node NFS clusters. Most of the nodes either have an entire ring offline or only 1 node in a ring. Example: (Node1 Ring0 333 Ring1 n33 | Node2 Ring0 033 Ring1 3n3 | Node3 Ring0 333 Ring 1 33n)

Currently it's not possible. However you should be able to put the cluster into maintenance mode, restart pacemaker_remote, then take the cluster out of maintenance mode. Test it to be sure. I believe the connection resource might be marked as failed, but the cluster should be able to reconnect

[ClusterLabs] How to reload pacemaker_remote service?

2020-06-09 Thread Gilbert, Mike
Hello all, We are running Pacemaker 1.1.21-4 and are trying to figure out how we can do the equivalent of “systemctl reload pacemaker_remote”. Does anyone know what signal needs to get sent to the pacemaker_remoted service to reload its config? Sending a SIGHUP appears to kill the process.
