 Did you identify any errors in the Engine log that could provide any
clue ? 
unfortunately no.

but funny thing... today I looked into html source of cluster settings 
page (via Firefox's web developer console). Gluster checkbox has this 
html code

<input type="checkbox" value="on" 
id="ClusterPopupView_enableGlusterService" tabindex="17" 
style="vertical-align: top;" disabled="">

when I edited and removed disabled="" part, I was able check that 
checkbox. After pressing Ok everything seems to be set but there are 
finally three relevant errors in the engine.log

2022-08-03 00:22:36,795+02 ERROR

Any idea why?

     well, it blocks me from any changes on cluster so it is serious
     problem... but personally I don't like this "new cluster and
migration"
     approach :-(

     Would anyone from oVirt/gluster developers have a look?

     Thanks in advance,
