Moving proxmox cluster servers physically. How to proceed to not broke quorum?

[Nakata]

Hello,
i need to move my server rack with 8 Proxmox servers to different location.
My network interfaces where the quorum is running on internal network /not the internet/. I can move all servers at once, or better i preffer to move one after another to reduce downtime
How to proceed, when i do not want my quorum get broken ? Is there some option to put cluster to some kind of service mode ?

For example, sometimes i work wih pacemaker, where i can use command "crm configure property maintenance-mode=true" and cluster is not broken during restarts or services.

Do i have some similar options with Proxmox cluster? Do you have some suggestions how to move servers and not to get quorum broken ?
Regards
RH

Hi,

You can remove security 3 nodes without any config adaption.
But you can also set the expected votes to 1.

pvecm  expected 1

This setting is not persistent.

But be sure that HA is disabled if you use it.
