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,

From the traceback it looks like nova-compute is running out of a venv.
You need to activate the venv, most likely via: source
/openstack/venvs/nova-12.0.16/.venv/bin/activate then run: pip
freeze. If you don’t see the RBD stuff – then that is your issue.
You might be able to fix via: pip install rbd.
Venv’s are self-contained python installs, so they do not use the
system level python packages at all.
I would also ask for some help in the #openstack-ansible channel on
irc as well.

backed (ansible Liberty setup)
Hi all,
We have a openstack-ansible setup and have ceph installed for the
backend. However whenever we try and launch a new instance it fails to
launch and we get the following error:

It moans about the rbd python libraries not being found, however all
of the rbd libraries appear to be installed fine via apt. ( We are
running Ubuntu)
Compute host packages:
dpkg -l | grep ceph
ii ceph-common 10.2.3-1trusty amd64
common utilities to mount and interact with a ceph storage cluster
ii libcephfs1 10.2.3-1trusty amd64 Ceph
distributed file system client library
ii python-ceph 10.2.3-1trusty amd64
Meta-package for python libraries for the Ceph libraries
ii python-cephfs 10.2.3-1trusty amd64
Python libraries for the Ceph libcephfs library
dpkg -l | grep rbd
ii librbd1 10.2.3-1trusty amd64 RADOS
block device client library
ii python-rbd 10.2.3-1trusty amd64
Python libraries for the Ceph librbd library
Has anyone come across this before? Ceph is working fine for Glance,
it just seems to be with the nova compute hosts.
Many thanks,
