Hello,
I have a cluster that sometimes has intermittent network issues on the heartbeat network.
Unfortunately improving the network is not an option, so I am looking for a way to tolerate longer interruptions.
Previously it seemed to me the post_fail_delay option is suitable, but after some research it might not be what I am looking for.
If I am correct, when a member leaves (due to token timeout) the cluster will wait the post_fail_delay before fencing. If the member rejoins before that, it will still be fenced, because it has previous state?
From a recent fencing on this cluster there is a strange message:
Aug 24 06:20:45 node2 openais[29048]: [MAIN ] Not killing node node1cl despite it rejoining the cluster with existing state, it has a lower node ID
What does this mean?
And lastly is increasing the totem token timeout the way to go?
Thanks,
Vasil Valchev
