changing cluster network Switch

[powersupport]

Hi,

We have a cluster with three nodes and due to some issues we are proceeding to change the cluster network switch.
May I know will there be any downtime for the VM's if we proceed to change the cluster network switch ?

Please note that our VM and Ceph networks are different. So may I know will there be any downtime for VM's if we proceed to change the cluster network switch ?

Kindly advice.

Thank You

only if you have HA enabled, you need to disable pve-ha-lrm && pve-ha-crm first.

the proxmox /etc/pve will be read only when the switch will be down (so you can change any vm config,...), but vm && ceph will run without any problem (if they are on another network/switch of course)
