Quorum Down After Firewall Change


New Member

I probably did something really stupid. I was working on configuring the Firewall for our cluster with a security group that all nodes were part of. I added the Rule IN DROP to the security group and suddenly the quorum went down and I can't edit the cluster.fw file, "error writing lock file : permission denied."

I would assume if I removed each node from the security group the quorum could come back up. But I can't find where I can do that without running into "error writing lock file : permission denied."

Does anyone know how I can remove a node from a security group when quorum is down?

I found a solution. I was able to run pve-firewall stop on each node to stop the firewall, then quorum recovered and I was able to disable the firewall for the cluster and remove the rule.
