[one-users] Ceph datastore monitoring in OpenNebula

[Alvaro Simon Garcia]

Hi all


We have included our ONE nodes into Ceph cluster, cephx auth is working 
but OpenNebula is not able to detect the free space:



> $ onedatastore show 103
> DATASTORE 103 INFORMATION
> ID             : 103
> NAME           : ceph
> USER           : oneadmin

> TYPE           : IMAGE

> TM_MAD         : ceph
> BASE PATH      : /var/lib/one//datastores/103

>  103 ceph                  0M -     -                 0 img ceph     ceph



but if we run rados as oneadmin user:

> 0           0            0 0            0            0

>   total avail   140846865180
>   total space   140848447032



It's working correctly (we are using one pool and libvirt ceph id)

the oned.log only shows this info:
Tue Jun 17 10:06:37 2014 [InM][D]: Monitoring datastore default (1)
Tue Jun 17 10:06:37 2014 [InM][D]: Monitoring datastore files (2)
Tue Jun 17 10:06:37 2014 [InM][D]: Monitoring datastore ceph (103)
Tue Jun 17 10:06:37 2014 [ImM][D]: Datastore default (1) successfully 
monitored.
Tue Jun 17 10:06:37 2014 [ImM][D]: Datastore files (2) successfully 
monitored.
Tue Jun 17 10:06:37 2014 [ImM][D]: Datastore ceph (103) successfully 
monitored.

Any clue about how to debug this issue?

Thanks in advance!
