Pause cluster and upgrade network

[mikiudon]

Hi guys,

It seems I'm having issues with corosync reporting unreachable hosts every now and then.

I put the storage network as 10.254.16.x/24 network and the management/cluster as 10.254.10.x/24

Though they are on the same switch without any VLAN-ing. I'm not sure but would that be the cause of the problem?

So I am trying to move the cluster network into a new switch physically itself. In between, I need to unplug the cables so I was wondering if there is a way of stopping the clustering without causing issues, then move everything properly, then start it up again.

Thanks

It shouldn't.

A switch connects relevant ports only if they communicate.

Decades ago there were Hubs. This kind of network connection box did actually connect ALL ports to all ports. If you have such an ancient device then your concerns would qualify.
