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.

Good luck

Mika

Hi Mika,

i did a test on my 5.x test cluster. I started with the dist-upgrade
stretch -> buster, which went fine. But "updating" from the
glusterfs
packages stretch -> buster was not possible, i had to deinstall the
stretch packages and reinstall the buster packages.

For me it looks like that it isn't important which one you do first.


Regards,
Hubert
