    Hello all: As I rebuilt my Proxmox cluster from scratch, I attempted to configure ACME certificates for the first time. I had no issues and got all (3) nodes working initially. The following day, I could not log into nodes 2 and 3 via the UI but could via SSH. The only change was that the ACME...

    Setting Up a Dynamic Proxmox Cluster with Normally-Off Nodes (Non-HA Setup)

    Hello Proxmox Community, I'm working on a home lab and need to save power, so most of my nodes are powered off most of the time. My goal is to set up a Proxmox cluster that can dynamically scale as nodes are powered on and off without requiring high availability (HA) or strict quorum. I’m fine...

    Automatically reduce quorum nodes after partial cluster shutdown

    Hello, From what I see, the corosync uses max number of cluster nodes+1 as a quorum for the cluster. So in 11 node cluster, 6 is the quorum. This is logically ok, but in real life scenarios, I need to have part or cluster to shutdown, and if shut down part is 5, then one more node and cluster...

    Leave a cluster ... am I doing something wrong?

    When you remove a PVE host from a cluster, it seems to be pretty b0rked after that. The cluster itself requires the pvecm remove thing and also delete the /etc/pve/nodes/nodename and also manage the ssh keys. Hope ya didn't have HA configured. It's messy, but after enough cleaning, you can...
