First upgrade gluster or > the operating system? > Hello Hubert, i needed to do this a while ago, in my case it was a Proxmox-Cluster based on the Debian Stretch upgrade to Buster while also upgrading gluster up to v7. The way i did it: 1. i had the "normal" stretch gluster packages installed (3.8) not the backports (4.1), so i first needed to upgrade gluster to 3.12 and move on from there (see [1]). You may be able to skip the next step. 2. i activated the old-releases gluster repos for 3.12 [2] and upgrade from 3.8(debian) to 3.12(gluster) 3. after this i switched to the "latest" repo and upgraded to v7 while still running stretch 4. then i upgraded stretch to buster, while gluster repos where commented out 5. after the dist-upgrade i switched the gluster repos to the buster ones and activated them again I write this all from memory as i am not at work atm, but this should be it. I also can say, that i did all the upgrades online (couldn't afford to stop all the vm's) - and to my surprise everything went without a big problem.
