Reverting cluster creation or simply changing it's interface.

[FormerVMW]

I read this page: https://pve.proxmox.com/wiki/Cluster_Manager, but I would like a sanity check.

When I first deployed the node I clicked the "create cluster" button not realizing I was doing something pretty important.

This single host has never had another host joined with it... yet.

Since that first time I hit "create cluster" I've done more learning and realize I need to use a separate network. I'd like to correct this mistake and change the cluster setup from using the primary NIC for communication and have it setup to use NIC3. With ProxMox providing the join information with the IP from NIC3.

Is this as easy as editing corosync.conf and changing the IP to the IP I've configured on vmbr3 (backed by NIC3)?

nodelist {
node {
name: server1
nodeid: 1
quorum_votes: 1
ring0_addr: 10.10.11.254
}
}

You can change the /etc/pve/corosync.conf, don't forget to increase the config_version! If you change a network, the Corosync service needs to be restarted.

Though if that is all you got, a single node, consider removing the cluster. It doesn't give you anything. The docs about separating a node from a cluster should apply here as well: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#pvecm_separate_node_without_reinstall

Thank you. I plan on adding a second node tomorrow and wanted to the get the initial mistake corrected before I did that. Very impressed with ProxMox so far.

that is why you should restart the service if you only change the IP address of an existing link

Also, please consider using [CODE][/CODE] blocks around any config file contents and such. It makes reading them a lot easier.
