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

This issue has been recorded as a feature
request recently,

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

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

[Deepak Naidu]

Not sure, if this is still true with Jewel CephFS ie

cephfs does not support any type of quota, df always reports entire cluster 
size.

Subject: CephFS mount shows the entire cluster size as apposed to 
custom-cephfs-pool-size

Greetings,

I am trying to build a CephFS system. Currently I have created my crush map 
which uses only certain OSD & I have pools created out from them. But when I 
mount the cephFS the mount size is my entire ceph cluster size, how is that ?


Ceph cluster & pools

[ceph-admin@storageAdmin ~]$ ceph df
GLOBAL:
SIZE  AVAIL RAW USED %RAW USED
4722G 4721G 928M  0.02
POOLS:
NAME  ID USED %USED MAX AVAIL 
OBJECTS
ecpool_disk1220 0   1199G   
 0
rcpool_disk2 240 0   1499G  
  0
rcpool_cepfsMeta 25 4420  0  76682M
20


CephFS volume & pool

Here data0 is the volume/filesystem name
rcpool_cepfsMeta - is the meta-data pool
rcpool_disk2 - is the data pool

[ceph-admin@storageAdmin ~]$ ceph fs ls
name: data0, metadata pool: rcpool_cepfsMeta, data pools: [rcpool_disk2 ]


Command to mount CephFS
sudo mount -t ceph mon1:6789:/ /mnt/cephfs/ -o 
name=admin,secretfile=admin.secret


Client host df -h output
192.168.1.101:6789:/ 4.7T  928M  4.7T   1% /mnt/cephfs
