Hello,
I hope this is the right mailing list for this question.
Problem:
On a cman cluster with two redundant rings running on Centos6.3, Ring 1 is
marked as faulty every few seconds and then recovers again.
Ring 0:
Two 10Gbe adapters bonded in mode 1 (bond0)
Ring 1:
An 1Gbe adapter connected to a dedicated “ secondary ring network”
Could you post the corosync version and the configuration file?
# corosync -v
Corosync Cluster Engine, version '1.4.1'

I use cman therefore I do not have a corosync.conf file
cluster.conf
