Fixes `bug 1581230`_ by removing the internal ``check_attach`` call from
|
|
the Nova code as it can cause race conditions and the checks are handled by
|
|
``reserve_volume`` in Cinder. ``reserve_volume`` is called in every volume
|
|
attach scenario to provide the necessary checks and volume state validation
|
|
on the Cinder side.

other:
|
|
- |
|
|
By removing the ``check_attach`` internal call from Nova, small behavioral
|
|
changes were introduced.
|
|
|
|
``reserve_volume`` call was added to the boot from volume scenario. In case
|
|
a failure occurs while building the instance, the instance goes into ERROR
|
|
state while the volume stays in ``attaching`` state. The volume state will
|
|
be set back to ``available`` when the instance gets deleted.
|
|
|
|
Additional availability zone check is added to the volume attach flow,
|
|
which results in an availability zone check when an instance gets
|
|
unshelved. In case the deployment is not sensitive to availability zones
|
|
and not using the AvailabilityZoneFilter scheduler filter the current
|
|
default settings (cross_az_attach=True) are allowing to perform unshelve
|
|
the same way as before this change without additional configuration.
