[pve-devel] corosync problems - need help

What kernel do you run? 2.6.32 or 3.10.0?
What is different on those nodes? kernel,  network cards?

Does it help if you restart the cluster file system:

# service pve-cluster restart

Note: You also need to restart depending services afterwards:

# service pvedaemon restart
# service pveproxy restart
# service pvestatd restart

On all nodes?

I guess you already tried to reboot that node?
