[ClusterLabs] Redudant Ring Network failure

[ROHWEDER-NEUBECK, MICHAEL (EXTERN)]

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)

corosync-cfgtool -R don't help
All nodes are VMs that build the ring together using 2 VLANs.
Which logs do you need to hopefully help me?

Corosync Cluster Engine, version '3.0.1'
