Dear ceph users,
We have been recently trying to use the two quota attributes:
- ceph.quota.max_files
- ceph.quota.max_bytes
to prepare for quota enforcing.
While the idea is quite straightforward we found out we cannot set any
additional file attribute (we tried with the directory pinning, too): we
get a straight "permission denied" each time.
We are running the latest version of Mimic on a cluster used exclusively
for cephfs.
This is the output of a "ceph fs dump"

and the command we are trying to use:
setfattr -n ceph.quota.max_bytes -v 100000000 /user/dir
It should be all pretty much default and we could find no reference
online regarding settings to allow the setfattr to succeed.
Any hint is welcome.
Kind regards
mattia
