This then sets the root password of the new node to the same thing. We are required to change root passwords on systems every 30 days.
Does changing the root passwords of the nodes change this 'cluster password' for joining new systems, or is it just the password of the system you use when joining?
I know that once you are connected to one system you can ssh to any of the others since it is using keys, but are there any consequences of changing the root passwords of the various nodes?
Thanks,
Neil

Bu default in PetaSAN, all nodes have the same root password, we call it the "cluster password". But this is not enforced, you can make them different if you wish, and update them differently.
When you join a new node, you need to enter the root password of the nodes you are joining ( typically the first node, but you could use the 2nd or 3rd to join). In this step, we also set root password of the joining node to the "cluster password" or to be more accurate to root password of the node you are joining assuming your nodes use different passwords.
Internally we use secure keys to connect among the nodes for communication, we do not use password. In fact root password is never stored on the system.
