Vladislav,
Hello!
I have the cluster based on pacemaker and corosync. The cluster nodes are
located in several data centers. And there is up to 450 ms ping latency
between some of the nodes. Sometimes these delays lead to split brains.
Yep, that's quite a lot. Enlarge token timeout so something like:
totem {
...
token: 5000
...
}
will help
I have found themax_network_delay option for the corosync.
This options does nothing until heartbeat_failures_allowed is set. I
don't know if you have it enabled, but I would recommend to not enable it.
Regards,
Honza
But there is a warning:
It is not recommended to override this value without guidance from the
corosync
community.
Can anyone help me with this?
