    Hi,

    The question may be stupid, however I need to update the switch where the nodes in a cluster are (not with shared storage).

    It’s clear that doing this will make the quorum unavailable, does it make any problem right now ? I mean, let’s imagine the switch dies or whatever, should I be worry on the fact that my running VMs will be powered down with the three nodes and won’t power up because the switch is not yet replaced...

    Sorry if this is a stupid question but I haven’t found any concrete answer.

    Thanks!

    Hi,
    Only if you have HA active and/or the pve-ha-lrm is active (not idle).
    If you have no HA and lose the cluster communication network the only thing what is happening you can't manage your cluster.
    The VM stay in there state.

    Hi Wolfgang,
    Thanks for the answer!
    When the network is back, I should be able to manage the cluster as before right, without doing anything else (I mean no reboot).

    Thank you,
