Can you set quotas on the application directories as well?
setfattr -n ceph.quota.max_bytes -v  
/environment/application1

Ali told me that the rpm for Ganesha's CephFS FSAL(driver),
nfs-ganesha-ceph v2.5.0.1 (28th June) available at download.ceph.com,
was built using libcephfs2 of Ceph luminous release v12.0.3.

AFAIK Ali's working on building latest nfs-ganesha, and nfs-ganesha-ceph FSAL
(v2.5.0.4) rpms and debs using libcephfs2 in latest luminous release, 12.1.1.
You can expect them to be at download.ceph.com/nfs-ganesha sometime soon.

Re: [ceph-users] CephFS mount shows the entire cluster size as apposed to custom-cephfs-pool-size

... instead of CephFS data pool's size.

This issue has been recorded as a feature
request recently,
http://tracker.ceph.com/issues/19109

If you were interested in setting quota on directories
in a FS, you can do that. See doc,
http://docs.ceph.com/docs/master/cephfs/quota/

You'd have to use the FUSE client (kernel client
does not support quotas),
http://docs.ceph.com/docs/master/cephfs/fuse/
and set a client config option,
client_quota = true
in Jewel releases (preferably use the latest v10.2.6).
An existing quota issue that was recently discussed
is here,
http://tracker.ceph.com/issues/17939
