Also will need to upgrade about 80 clients as well. Given that a complete removal of gluster will not touch the 200+TB of data on 12 volumes, we are looking at doing that process, Stop all clients, stop all glusterd services, remove all of it, install new version, setup new volumes from old bricks, install new clients, mount everything. </div><div><br></div><div>We would like to get some better performance from nfs-ganesha mounts but that doesn't look like an option (not done any parameter tweaks in testing yet). At a bare minimum, we would like to minimize the total downtime of all systems.</div><div><br></div><div>Does this process make more sense than a version upgrade process to 4.1, then 5, then 6? What "gotcha's" do I need to be ready for? I have until late May to prep and test on old, slow hardware with a small amount of files and volumes. </div><div><span><pre><pre>-- <br></pre>James P.

Every time you stop a school, you will have to build a jail. What you
gain at one end you lose at the other. It's like feeding a dog on his
own tail. It won't fatten the dog.
