Hi, so I managed to get Cinder to work with nfs, ceph and SMBFS creating 
a multi-tier architecture. The permissions on the smbfs server are still 
a small problem but when inherited and automatically changed, it works 
very well.. also VERY fast.
On to the next issue.
I have glance images currently on ceph and thats ok but every time I 
deploy a volume to the smb tier, it downloads the image the control node 
(why?!?!?) and then creates the volume into smb or nfs .
Its very very very slow.
I tried to make a glance image-volume but I keep getting the following 
error.
ERROR glance.common.wsgi AttributeError: 'Store' object has no attribute 
'volume_id'
The default glance store is now cinder ( was rbd), all the cinder 
options are enabled and yet its a no go.
Is there something else I need to change?  The volume does exist on 
cinder and if i change the name of it, i get the url was malformed so it 
seems it finds the file but somehow it cannot add the volume id into the 
metadata?
this is what i run:
openstack image create --disk-format raw --container-format bare 
Linux-SMBFSTEST
which returns to me a uuid of: b97704ba-7b22-493d-a3bb-4ce597c9ddc2
and then I run
glance location-add --url cinder://e080103c-049e-4d91-9a3c-5322a505e5a4 
b97704ba-7b22-493d-a3bb-4ce597c9ddc2
the cinder volume being volume-e080103c-049e-4d91-9a3c-5322a505e5a4 and 
fully accessible with no permission restriction..
any help? anyone?
Thank you already
