New Cluster - IP question

[rsiera]

I'm new to PMG. Managed to start up two instances and put them into cluster. Cluster sync was successful.
But I noticed a difference in listing of the two nodes.

Indeed, both nodes have two NICs. One with private and one with public IP.
At install time of the second node I used the public nic, while when installing the first node I specified the private nic. So, that must be the reason.
But how do I normalize this? Or should I ignore it?

But how do I normalize this?

* make a backup
* remove the one node you want to change - with `pmgcm delete <nodeid>`
* setup a fresh pmg
* join it using the correct address

Or should I ignore it?

that depends on your setup and needs - in general pmg's cluster stack works over ssh (and a few utilities on top) - so if this works reliably you could leave it - then again - in my experience such inconsistencies in config have a tendency to cause trouble when you don't expect it

I hope this helps!

Ok, clear.
Two minor questions before proceeding.
a) I can safely remove the master? or is it bester to follow these two steps?
b) I should best remove the subscription first, to reapply it later?
