                  In the case of rolling upgrades across
                    a cluster if I have my storage and vm hosts on
                    separate machines what order would I want to update?
                    

                    Clients first or storage nodes first?  

                    
                Storage servers first followed by clients is the
                recommended way.

              
            Thanks.  And I imagine I would want to leave op-version
              update till after clients are updated also.
            Clients shouldn't need to refresh mount post op version
              update should they?  Just after gluster update to make
              sure its using updated 3.7.13 files in its mount.
          
        
    If you are updating both clients and servers to the same version, I
    don't think you explicitly need to bump up the op-version
    explicitly.

    But after updating the client(s), you *will* need to umount and
    mount again to ensure that it is running the latest version.
