Charm cinder-ceph now requires 'ceph-access' relation to Charm nova-compute
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In order to ensure a functional nova-compute application, the 'ceph-access'
relation is now required between the cinder-ceph charm and the nova-compute
charm when cinder-ceph is related to the cinder charm. Otherwise, the charm
will go into the blocked state.
This is due to this change:
Without a relation to at least one nova-compute application a cinder-ceph
backend will not be functional as the libvirt secrets will not have been
created to allow access to the ceph cluster from libvirt/qemu.
-- `Require relation to nova-compute application`_
This probably won't affect most existing, deployed, clouds, but *may* affect
test bundles that now won't complete deployment.
To add the relation:
.. code-block:: none
juju add-relation nova-compute:ceph-access cinder-ceph:ceph-access
All bundles that use cinder-ceph should be checked and the relation added.
