Can't add a node into 4.1 cluster

[garnaz]

Hello!
I'm having a big trouble with adding a new node into 2-node ProxMox 4.1 cluster.
The steps I performed before:
1. Tried to add the node - unsuccessful, since the node was in a different subnet/gateway.
2. Deleted the node from the cluster. Cluster quorum Ok.
3. Moved the node into the same subnet with changing it's IP and host name.
4. Tried to add the node again and received "authorization key already exists" message.
5. Added the node with -force. Node added, though there was no quorum with "Activity blocked" error.
6. Deleted the node from cluster and reinstalled ProxMox on that node.
7. Added the node to the cluster. The same error - Quorum: 2 Activity blocked.

There are no problems with the other 2 cluster nodes.
Please help. Thanks in advance.

Hello!
4. Tried to add the node again and received "authorization key already exists" message.

If you mean "authentication key already exists" it happens when you are adding node2 from node2, that is wrong (you have to go to node2 and issue the "pvecm add IP_of_node1" command).
Also check if multicast works. "De clustering" a node seems not trivial, don't know if you can start from scratch on both nodes. I've found very usefull create 2-3 guest proxmox VM in my proxmox server and do tests there (with snapshotting of the starting point and rollback if I did some mistake).

Thank you very much.
The problem was just solved. It was really a multicast problem with that particular node.
