    I'm working on upgrading a set of our gluster machines from 3.7
      to 3.10- at first I was going to follow the guide here: https://gluster.readthedocs.io/en/latest/Upgrade-Guide/upgrade_to_3.10/
    but it mentions:
     
    
        Online upgrade is only possible with replicated and
          distributed replicate volumes
        Online upgrade is not supported for dispersed or distributed
          dispersed volumes
      
    
    and 

     
    ALERT: If any of your
      volumes, in the trusted storage pool that is being upgraded, uses
      disperse or is a pure distributed volume, this procedure is NOT
      recommended, use the Offline
        upgrade procedure instead.
    

    The data stored on this gluster volume (Distributed-Disperse, 2 x (4
    + 2) = 12) is somewhat critical, but I wanted to make sure there was
    no possible way to do an 'online' upgrade before following the
    'offline' steps.
