[SOLVED] Is there a way to disable cluster while it's not in use?

[wingyiulam]

Hi all,

I am planning to only use cluster for moving CT/VM between server when needed; there is no reason for me to turn on all servers 24/7 for a home lab. Is there a way to disable clusters while nodes aren't in use? it seems like PVE gets quite a bit of errors of fetching each node after I shut down all the related systems.

Thanks,
Wing

Proxmox clusters use quorum and turning off nodes is not really supported.

There is support for migration of CT/VM between Proxmox nodes without needing to cluster the nodes, which might be a better fit for your use case. Currently remote-migration needs to be done from the command line, but it's on the Proxmox roadmap: https://forum.proxmox.com/threads/multi-datacenter-management.66830/page-2#post-515033

Is there a way to disable clusters

@leesteken is right, of course.

That said, as it is for a Homelab you might search for "pvecm expected", read everything, understand it and then possibly find this a way to solve your problem. The concept of "Quorum" and the possible help of a "Quorum Device" still applies here.

One pitfall for me was: if you want to modify the structure of the cluster (or perhaps any cluster-wide aspect) make sure all Nodes are up and running first.
