Disable lazy translation
Late in the Havana cycle bug 1225099 was found in the lazy
translation code, and to be safe it was decided to disable lazy
translation for Havana. This change does that.
The backup service now keeps a dictionary of managers
for each type of volume backend. If multi backend is
not in use (and volume_type is None) the current
volume_driver is used.

Dont retry if target creation succeeds
The target creation retry loop was not breaking when
the target was succesfully created. This is "sometimes" ok,
however in other cases this will actually cause a failure in
the second create and the backing Lun will be deleted and not
created again succesfully due most likely to a busy status on the
target.
This patch fixes XML serializer for QoS Specs exension calls like
list(), show(), associations(). Note that using XML as input for
create(), update() doesn't support yet.

Add debug logging for targets
Seems we may be failing target create silently,
the situation appears to be that the actual device
lun is not created. This has been appearing in the
gates on create from snapshot.
This change adds some logging that will help us determine
if it's the actual create, or if it's the attempted update
while the dd process is possibly holding the volume in a busy
state causing the target update to add lun 1 to fail.

Fix translation of CinderExceptions in REST API
When creating a Fault from a CinderException wrapped in an
HTTPException, we were converting the inner explanation to unicode
before it was able to reach the Fault's call() method which is where
translation occurs, and unicode objects can't be translated.
This patch preserves the CinderException's Message object and puts it in
another Message object as the explanation to the HTTPException so it can
be translated.

Allow upgrade from Grizzly with ThinLVMVolumeDriver
In Grizzly, LVM thin provisioning was used by setting
volume_driver=...ThinLVMVolumeDriver. In Havana this
functionality has moved under the standard LVM driver
with the option "lvm_type=thin" used to enable it.
We should account for the old volume_driver class path
so that the volume service behaves as expected for users
upgrading from Grizzly ThinLVM configurations.
Calls to create_volume (both volume_rpcapi and scheduler_rpcapi) pass
mandatory args as optional and reverse. This patch fixes the calls to be

Also, fix the call to create_volume in the migration code where
allow_reschedule defaults to True, but we don't pass request_spec so it

LVM volume_clear: error on unexpected inputs
Currently if a user configures

the LVM driver will silently delete a volume and not wipe it.
Instead, the delete operation should fail, leaving the volume

Fix finish_volume_migration() on SQLAlchemy 0.8.x
In SQAlchemy 0.8.x "Unconsumed column names" warning became
an exception, so refering to a non-existent column in insert()
or update() call raises an error.
finish_volume_migration() calls Session.update() method passing
values of two non-existent columns as arguments (volume_metadata,
volume_admin_metadata, volume_type). These two are not table columns
at all, but rather SQLAlchemy models relationships.
As SQLAlchemy ORM implements Unity of Work pattern, we should not
really track changes to a model instance manually at all, because
Session class already does it for us. finish_volume_migration()
is refactored to take benefit of this fact.
Add a specific filter for /usr/local/bin/hus-cmd, rather than adding
/usr/local/bin to the list of exec_path in rootwrap.conf. This allows to
sync rootwrap directly from oslo-incubator without having to edit the
default value for exec_dirs.
Allow v2 Volume API to create volume with type name
v2 API only accepts volume type ID when creating volume, while v1

Fix issues with failed lvremove
There are some race conditions that

This is a difficult issue to reproduce, and there's

The patch adds a catch on the lvremove failure,
followed by a udevadm settle and a retry of the

any force delete failures.
The other option that had been proposed was using dmsetup remove
but there are concerns that this may cause problems.
