Question on Proxmox Node Maintenance

[Seed]

Hello,

I want to do some maintenance on one of my nodes. I'm currently running a 3/2 with 3 nodes and 3 disks per node. Can I just shut one down, do the work for an hour or so then put it back in?

Hi

If you have no ceph storage on the cluster and no HA service enabled then you do this without preparations.

Hello,

Im not sure what this means.

• I have a large disk mounted that is on the volume pool.
• I have no HA service enabled

The 1 VM that is running on it is on a local disk to that node. It's only the large volume that has a disk also mounted to that VM.

Then you can turn off the VM and shut down the host without affecting the other nodes in the cluster.

The host that's running the VM wont be the same one as the one I need to upgrade. That VM host should still run and CEPH should still function right? I assume when I add the node back in, it will resync?

I do not understand your setup.
You say

And now you say you have Ceph?

yeah. I mean I mentioned a volume pool but I guess that wasn't clear enough. CEPH across the 3 nodes with 3 disks per node.
