Create/Quota/Mount pool

Create/Quota/Mount pool

[Chu Duc Minh]

Hi, i'm searching a way to create more data(s) pool and quota for each pool.
Do you know how to select pool to mount when using ceph client. (i'm 
using kernel 3.0.x)

Thank you very much!

You can create pools with 

 ceph osd pool create <poolname>

make them usable by the fs with

 ceph mds add_data_pool <poolname>

and then set a subdirectory to use that pool for new files with cephfs 
(man cephfs).

If you run into problems, let us know; this isn't well documented yet!

Hi, how can I know the ID of new <poolname>, because it's needed for 
cephfs command? Or i must use numeric <poolname>?
I'm using Cephx for auth, how can i set permission for a individual 
client only can mount & see a specify subdirectory/pool?
I succeeded when using numeric poolname but fail on "ceph auth add ..." 
and mount.
(I tried many options for ceph auth add ... - but still does not success)

Thank you very much!
