The ``[workarounds]/ensure_libvirt_rbd_instance_dir_cleanup`` configuration
|
|
option has been introduced. This can be used by operators to ensure that
|
|
instance directories are always removed during cleanup within the Libvirt
|
|
driver while using ``[libvirt]/images_type = rbd``. This works around known
|
|
issues such as `bug 1414895`_ when cleaning up after an evacuation and
|
|
`bug 1761062`_ when reverting from an instance resize.
|
|
|
|
Operators should be aware that this workaround only applies when using the
|
|
libvirt compute driver and rbd images_type as enabled by the following
|
|
configuration options:
|
|
|
|
* ``[DEFAULT]/compute_driver = libvirt``
|
|
* ``[libvirt]/images_type = rbd``
|
|
|
|
.. warning:: Operators will need to ensure that the instance directory
|
|
itself, specified by ``[DEFAULT]/instances_path``, is not shared between
|
|
computes before enabling this workaround, otherwise files associated with
|
|
running instances may be removed.
