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.

I have found themax_network_delay option for the corosync.

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?
