[gpfsug-discuss] help with multi-cluster setup: Network is unreachable

[Buterbaugh, Kevin L]

Hi Eric, Jamie,

Interesting comment as we do exactly the opposite!

I always make sure that my servers are running a particular version before I upgrade any clients.  Now we never mix and match major versions (i.e. 4.x and 3.x) for long … those kinds of upgrades we do rapidly.  But right now I’ve got clients running 4.2.0-3 talking just fine to 4.2.2.3 servers.

To be clear, I’m not saying I’m right and Eric’s wrong at all - just an observation / data point.  YMMV…

Kevin

Hi Jamie:

I think typically you want to keep the clients ahead of the server in version.  I would advance the version of you client nodes.

New clients can communicate with older versions of server nsds.  Vice versa...no so much.
