    [SOLVED] How to force a node to catch-up? config_version is behind by 1

    Hi there, I have added a new node (pve-nuc6-5) while one was offline (pve-nuc6-4). As a result, pve-nuc6-4 remains offline despite being accessible. I noticed that pve-nuc6-4 was one version (Corosync.conf) behind the rest of the cluster. How do I force it to sync to the last version...

    [SOLVED] Adding a new Node with VMs/LXCs to cluster

    So it seems that you cannot add a node to a cluster if said node already has VMs/LXCs configured and running. Presumably this is a failsafe in case of ID replication.

    Public-facing Proxmox cluster randomly loses http connection on nodes in a rotating/random fashion

    Recently hired, I don't think this is a perfect proxmox setup and would like to improve it. Currently, our proxmox cluster has its 3 nodes assigned public IP addresses that we use to connect to them. Fairly randomly, we lose http connection to a node(s) and then just connect to one of the...
