how to specify cephfs size?

[John Shen <johnshen64@xxxxxxxxx>]

It must be FAQ or something simple, but so far I cannot find how to change the file system size of the cephfs mount. i have over 1TB

However I could not find any parameter either on the server [mds] section or on the client mount to increase it to say 100GB.

I looked here for server configuration:

http://ceph.com/docs/master/cephfs/mds-config-ref/

i tried the man page for mount.ceph for any mounting parameter.

greatly appreciate your help!
