Hello all,
may be a noobish question, but I have a fire on the roof (metaphorically).

We had a network issue, and all nodes stopped seeing each other at the same time.
After we resolved the network issue, all cluster nodes seem to be on their own:

So the question is simple.
How can I rebuild the cluster?

Thank you very much for any quick answer.
 
Hi,

I have the same problem.
Multicast is ok on all my nodes but there every host is on a separate mini cluster.
Can you help me please?

Regards.
 
Ok guys it was a firewall issue.
I flush my iptables rules and everything is ok.
