Powering down a Proxmox 9.2 cluster: how-to needed

[engineer5]

I'm trying to shutdown a cluster for electrical utility work. After this work will be finished, I'd like the cluster to come up again to the normal (HA) state with minimal admin work. (Read: someone powers this on and all starts working again)

I've tried out the HA-freeze mode, but with HA frozen, I can't power down any qm.

So how is this supposed to work? Do I actually have to kill the HA setup? Then after re-booting the nodes, the qms are not coming up at all?

The cluster in question is a 2-node cluster with data and Quorum server on a NAS.

Thanks for all enlightenment here...

Hi @engineer5

thank you for posting on the forum!

So with the new HA disarm feature you can also chose to ignore the state of the VMs instead of freezing everything. This will still let you properly power down all the VMs.
After the maintenance you just have to rearm the HA stack and it will start all the VMs according to the HA config which are not already running due to "Start at boot".

Tested this with a small virtual cluster and worked as expected, but as always, ymmv.
