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 On May 8, 2017, at 11:34 AM, J.

I would advance the version of you client nodes. New clients can communicate with older versions of server nsds. Vice versa...no so much. _______________________________________________ gpfsug-discuss mailing list gpfsug-discuss at spectrumscale.org<http://spectrumscale.org> http://gpfsug.org/mailman/listinfo/gpfsug-discuss — Kevin Buterbaugh - Senior System Administrator Vanderbilt University - Advanced Computing Center for Research and Education Kevin.Buterbaugh at vanderbilt.edu<mailto:Kevin.Buterbaugh at vanderbilt.edu> - (615)875-9633 -------------- next part -------------- An HTML attachment was scrubbed...
