[one-users] ceph data store show 0M capacity

[Marco Lanzotti - ADGlamor]

Hi all, I'm new in OpenNebula!

I have a fresh instllation of OpenNebula 4.2 and Ceph 0.61 on Ubuntu 
12.04 LTS.

I created new pool:

ml at metal02:~$ sudo ceph osd pool create one 64

I created new datastore on OpenNebula using this conf:

NAME = "ceph"
DS_MAD = ceph
TM_MAD = ceph
DISK_TYPE = RBD
POOL_NAME = one
HOST = metal02

Now i see a 0 size datastore:

oneadmin at metal01:~$ onedatastore show 108
DATASTORE 108 INFORMATION
ID             : 108

I added /usr/bin/rados in sudoers with NOPASSWD as suggested here:
http://lists.opennebula.org/pipermail/users-opennebula.org/2013-July/023884.html

Now I can run rados as oneadmin user, but I still see a 0 size datastore.

Thanks in advance for your help!

Bye,
Marco
