Surprising! Will you be able to reproduce the issue and share the logs if I provide a custom build with more logs?

Thanks for your help! Much appreciated.
The fsid is the same for all bricks:
imagegluster1:

I already did try restarting the glusterd nodes with no effect, but
that was before the upgrades of client versions.
Running the "volume set" command did not seem to work either, the
shared-brick-counts are still the same (2).
However, when restarting a node, I do get an error and a few warnings
in the log: https://pastebin.com/tqq1FCwZ
