[SOLVED] How to temporarily take nodes out of the cluster

[kez]

Hi there,

What's the recommended way to take a node out of the cluster temporarily? - say if 1 node gets blacklisted etc. and you need to stop it sending emails.

I thought about shutting down the VPS but that breaks the Cluster menu on the Master UI. Also thought about simply stopping the postfix service. Not sure if there is a propper way?

Thanks.

shutting down a node should not break the cluster menu (but we'll discuss that in the other threads of yours)

simply shutting off a node is probably the way to go. you could ofc also remove the dns entry temporarily, but i guess that is 1. more work and 2. takes some time propagate...

each node will continue to work even when no other cluster members are left, so that should be no problem
(as long as you don't have a master though you won't be able to configure most things)
