Open Stack

Thanks Kris,

I have run the commands as suggested and there is no rbd installed. 
However when we try to manually install rbd with pip we get the 
following error:

pip install rbd
DEPRECATION: --allow-all-external has been deprecated and will be 
removed in the future. Due to changes in the repository protocol, it no 
longer has any effect.
Ignoring indexes: https://pypi.python.org/simple
Collecting rbd
   Could not find a version that satisfies the requirement rbd (from 
versions: )
No matching distribution found for rbd

I assume the playbooks are coming across the same issue which is why we 
are having this problem. I will also ask in the #openstack-ansible 
channel for some help.

Pip is using the local repo servers that are created by 
openstack-ansible (I assume) so looking at this, it appears they don't 
have the correct packages.

Regards,
