Planned Proxmox Cluster Maintenance

[Zwitscher_Tom]

Hi,

I have a three node Proxmox cluster 7.3-6.
The cluster needs to be shutdown for maintenance.
Is there a best practice for this?

My plan is:
1.) Disable the "Start at boot" option for every VM
2.) Shutdown all VMs
3.) Shutdown the three cluster nodes

After the maintenance:
1.) Boot up all cluster nodes
2.) Ensure the the quorum is up and running
3.) Start the VMs
4.) Enable the "Start at boot" option for every VM

What do you think?

Thanks

I don't think you need to disable "start at boot".

if a node is starting and don't have quorum, vm will not be auto started.

Start at boot is only working on ressources that are not in HA. Are you using ha?

Are you using Ceph?

no, start at boot works also without HA.

no, start at boot works also without HA.

Yes but it does not with HA, according to the docs?

oh sorry, miss read. Well , indeed, HA don't care about start at boot, but will start vm "after the boot", when the quorum is ok.
(It's mostly the same ^_^ )

Yeah I stumpled upon it because boot-order is also non-ha-only - so if you have ha enabled, you cant really manipulate the start/boot order of your vms (in ha). https://bugzilla.proxmox.com/show_bug.cgi?id=4701 (stills needs a reply .. damn )
