Since Ussuri, there is a bug in how Ceph (RBD) is handled with Cinder:
|
||||
the ``backend_host`` option is missing from the generated configuration
|
||||
for external Ceph. The symptoms are that volumes become unmanageable
|
||||
until extra admin action is taken. This does *not* affect the data plane
|
||||
- running virtual machines are *not* affected.
|
||||
|
||||
There is a related issue regarding active-active ``cinder-volume``
|
||||
services (single-host ``cinder-volume`` *not* affected), which is that
|
||||
they should not have been configured with ``backend_host`` in the first
|
||||
place but with ``cluster`` and proper coordination instead. Some users
|
||||
might have customised their config already to address this issue.
|
||||
|
||||
The Kolla team is investigating the best way to address this for all its
|
||||
users. In the meantime, please ensure that, before upgrading to Ussuri,
|
||||
the ``backend_host`` option is set to its previous value (the default was
|
||||
``rbd:volumes``) via a config override.
|
||||
|
||||
For more details please refer to the referenced bug.
|
||||
Do note this issue affects both new deployments and upgrades.
