With your hint I was able to find the relevant documentation: https://docs.ceph.com/docs/master/cephfs/client-auth/ that is completely absent from: https://docs.ceph.com/docs/master/cephfs/quota/#configuration I will send a pull request to include the link to client-auth in the CephFS quota page. thanks Mattia On 7/31/19 2:45 PM, Nathan Fish wrote: > The client key which is used to mount the FS needs the 'p' permission > to set xattrs. eg: > > ceph fs authorize cephfs client.foo / rwsp > > That might be your problem. > > On Wed, Jul 31, 2019 at 5:43 AM Mattia Belluco <mattia.belluco@xxxxxx> wrote: >> >> 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" >> >> Filesystem 'spindlefs' (4) >> fs_name spindlefs >> epoch 18062 >> flags 12 >> created 2019-02-21 17:53:48.240659 >> modified 2019-07-30 16:52:13.141688 >> tableserver 0 >> root 0 >> session_timeout 60 >> session_autoclose 300 >> max_file_size 1099511627776 >> min_compat_client -1 (unspecified) >> last_failure 0 >> last_failure_osd_epoch 31203 >> compat compat={},rocompat={},incompat={1=base v0.20,2=client writeable >> ranges,3=default file layouts on dirs,4=dir inode in separate >> object,5=mds uses versioned encoding,6=dirfrag is stored in omap,8=no >> anchor table,9=file layout v2,10=snaprealm v2} >> max_mds 1 >> in 0 >> up {0=10744488} >> failed >> damaged >> stopped >> data_pools [11] >> metadata_pool 10 >> inline_data disabled >> balancer >> standby_count_wanted 1 >> 10744488: 10.129.48.46:6800/549232138 'mds-l15-34' mds.0.18058 up:active >> seq 49 >> >> 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 >> _______________________________________________ >> ceph-users mailing list >> ceph-users@xxxxxxxxxxxxxx >> http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com -- Mattia Belluco S3IT Services and Support for Science IT Office Y11 F 52 University of Zürich Winterthurerstrasse 190, CH-8057 Zürich (Switzerland) Tel: +41 44 635 42 22 _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
