Hi Alberto,
We face a similar problem with Gluster 6.7 + NFS-Ganesha after a heal. However, on our side, the problem also affected the root user. We were able to move and delete the affected files but unable to copy, edit or chmod. The brick logs was the same as yours.
Since we restarted nfs-ganesha, it working fine.

Hi Alberto,
Sadly you should verify if the issue is the same.
Enable the trace logs for the bricks and verify if the errors in the logs with those in the bugzilla.Don't forget to stop the trace log or your logs' dir will get full.
Yes, the log is quite similar:

What version of gluster are you using ?
Gluster 6.6.
In my case only a downgrade has restored the operation of the cluster, so you should consider that as an option (last, but still an option).
We created a copy of the faulty's directory and put it in place of the older one to solve our issues for now. We kept the old one for further investigation.
You can try to run a find against the fuse and 'find /path/to/fuse -exec setfacl -m u:root:rw {} \;'
Maybe that will force gluster to read the ACLs again.
Running a setfacl doesn't make any difference. If we do a chmod it "fixes" the permission problem.
Good luck!
If you have the option, join the next gluster meeting and ask for an update (if the issue is actually the same).
Best Regards,
Strahil Nikolov
