As Mike Taylor pointed out in a previous post this was an incorrect statement. You can be at 4.2.x (ie 4.2.0, 4.2.1, 4.2.2, or 4.2.3) and still do a rolling upgrade. The minReleaseLevel is not pertinent to a rolling upgrade. The running daemon is the important part. So you can't have any 4.1.x nodes in your cluster and do a rolling upgrade to 5.0.
Also, Aaron, as to the OS support. This decision was not made without some angst. As I mentioned at the user group meeting in NYC...the key point is that we would like to get to a more current compiler. This will allow us to take advantage of newer features and functions and hopefully make the code better for customers. SLES 12 has been around for over 2 years. I hope this helps give some thinking behind the decision. Steve Duersch Spectrum Scale 845-433-7902 IBM Poughkeepsie, New York > Today's Topics: > > 1.
