Cluster : node failure

[odesport]

Hello,

Yesterday I tried to add a node to the new installed cluster. This node belonged to an other cluster before. It failed. I reinstalled this node but cman fails when I try to add it to the cluster. How can I clean the other nodes to delete all settings for this node I want to add to the cluster ?

The recommended way is to re-install the node.

I decided to install a new node with a new hostname and a new IP adress. When I added this node on the cluster, it hanged on "Starting cman". I stopped the process and restarted the server. On reboot, the node is in the cluster. But there is still a problem : I can't migrate VM to this new node :

When I start this new node, this error appears :

Starting PVE Daemon: pvedaemonunable to create socket - IO::Socket::INET: Cannot assign requested address

I think that the problem comes from SNMP which is intalled with Nagios. When I uninstall theses packages, I can add a node to the cluster.
