    Hi. I followed the guide https://pve.proxmox.com/wiki/Renaming_a_PVE_node, and renamed my main node, and also my cluster name. When trying to move a vm back to the newly named node, I get the error 2023-09-04 21:09:39 # /usr/bin/ssh -e none -o 'BatchMode=yes' -o 'HostKeyAlias=ravenclaw'...
  4. Corosync Best Practice

    I'm trying to figure out the best way to ensure corosync has its own network. Please let me know if any of these points weren't ideal and why: I created a VLAN with no gateway (just a space on my switch with a unique subnet) 10.5.0.X and set all 8x of my nodes to addresses on that subnet. I...

  14. Moving Physical Disk (USB) & VMs to new Proxmox Node

    I've been using Proxmox nodes in a cluster of 2 for awhile and they both have relatively low resources, so I bought a PowerEdge R720 that's a lot more capable. At the moment I'm low on storage and I've been using an external 4TB HD external HD on one of my existing nodes. I'd like to be able...

    This has started happening ever since PVE 7.4.x I can reproduce the issue 100% of the time when (bulk) stopping VMs and CTs on one Node, then (bulk) starting them back up again. As soon as the start command is issued, the VMs and CTs will migrate to a different Node, although they should just...
