Require assisted_volume_snapshots from novaclient
The "QEMU-assisted-snapshots for GlusterFS volumes" patch currently
does a try/except ImportError for the new assisted_volume_snapshots
extension in novaclient. That functionality is now in novaclient
2.15.0, so Cinder should consider this a hard requirement rather
than allowing it to be absent.

Fix issues with failed lvremove
There are some race conditions that
can cause problems with lvremove commands. In
most cases these seem to recover nicely just
with a simple retry of the lvremove. Adding
a udev settle seems to elimate the rest of them.
This is a difficult issue to reproduce, and there's
a suspiscion that it relates to failed target
creeates.
The patch adds a catch on the lvremove failure,
followed by a udevadm settle and a retry of the
lvremove. With the setup that I've been able
to reproduce this issue these changes have eliminated
any force delete failures.
The other option that had been proposed was using dmsetup remove
but there are concerns that this may cause problems.

GlusterFS: Copy snap from correct source file
The GlusterFS driver's copy_volume_from_snapshot was previously
not parsing the snapshot information to determine which backing
file to copy from, instead copying from the active file at all
times. This would result in the wrong data being supplied when
a volume is cloned from a snapshot.
Add a test for the copy_volume_from_snapshot method.

Add a retry to create_iscsi_target for LVM
There's a bug in the tgt driver where under certain
conditions where a race condition is present that can
result in tgtadm attempting re-use a target ID.
Testing this it seems that a retry will address this nicely
and cause tgtd to grab a new target ID and things are ok.
This patch adds a simple check/retry mechanism around the

Add volume metadata to v2
This exposes volume metadata in the Cinder v2 API. This already exists
in v1 and was originally suppose to exist back with Grizzly, but appears
to have slipped.
This updates the volume manager and the
backup manager to enforce that the driver
has been initialized.
The managers call the driver in many places
without ensuring that the driver has been
properly initialized. When the driver fails
inside of do_setup(), the managers shouldn't
call the driver's set_initialized() method.
The managers now dump out the exception, and
exit the init_host, leaving the driver in
an uninitialized state.
VolumeNotFoundForInstance class is used only in test_xiv_ds8k.py. I
think the exception class that is used only in test code should not be

Some Messages, such as those created from Invalid exceptions, use a

A mapping key of 'netloc' is always ignored. Thus information in

A mapping key of 'volume_id' is ignored when we use the non keyword

This change modifies the behaviour of the secure delete for thick
LVM snapshots to wipe the underlying COW of the snapshot LV
instead of the snapshot LV itself.
This change is necessary because the snapshot LV does not contain
exactly the same number of writable blocks as the original LV. The
COW includes header information per COW block that identifies the
device as a COW device as well as the source and destination blocks
for the changed item. The amount of metadata contained in the COW is
variable based on I/O performed on the snapshot.
This does not change the behavior of secure deletes on thin LVs
or secure deletes on the thick LV snapshot origin.

Moreover, simplify the "if..., elif..." module with "getattr"

According to the comment in the source code, the snapshot-update of
v2 would be able to allow either "name" or "display_name" parameter.
And if both paramters are specified, "name" parameter is effective
over "display_name" like "description" parameter.
However "display_name" parameter is ignored now, because cinder writes
over empty dict(update_dict['display_name']).

Turn db model object into a primitive object to avoid error
In volume API controller we need turn db model object into a primitive
object to avoid error when it adding visible administrator metadata to
volume's metadata dict.
When the driver copy_image_to_volume fails it can
at the current time raise more than just CinderException
as its root exception type. This causes rescheduling due
to the blacklisted exception list that is used to determine
if a exception is 'bad enough' to trigger rescheduling or
should the volume creation action just set the volume to
error state.
To avoid the situation where this would cause a rescheduling
we should make sure (for now) that any exception that is
emitted on copying an image to a volume is translated
into a image copy failure and reraised.

Previously deleting a key in certain qos specs was accomplished via
'update' API. Unfortunately, 'update' isn't able to tell the
difference between setting a key with no value and deleting a key (and
its value).
This change adds an new API 'delete_keys' to qos_specs API extension.
'delete_keys' API allows client to specify a list of to-be-deleted keys
in one single request (batch mode!), which can be handy when removing
multiple keys in a qos specs.
Example URL and request body for 'delete_keys' API:
PUT to http://127.0.0.1:8776/v2/qos-specs/QOS_SPECS_UUID/delete_keys
with body: {'keys': ['foo', 'bar', 'zoo']}
Above example request will result in 'foo', 'bar', 'zoo' key/value
pairs of QOS_SPECS_UUID be marked as deleted in DB. If QOS_SPECS_UUID
doesn't exist, a 404 error will return; if any key in 'foo', 'bar',
'zoo' couldn't be found in QOS_SPECS_UUID, a 400 error will return with
error message telling which key couldn't be found. Note that Cinder
will puke 400 and stop trying the rest once it encounters a
non-existing (or deleted) key amoung the given list of keys.
This change also fixes 'list'/'show' API includes deleted keys in
result.

Add check for qemu-img to image_utils fetch_to_raw
Some platforms, particularly PowerPC systems running RHEL,
do not have qemu-img installed by default and do not
support image formats other than RAW. For these systems,
functions/drivers that use fetch_to_raw() currently fail
because it is assumed that qemu-img will always be installed.
This change updates fetch_to_raw() to function more like the
upload_volume() function which checks the image format and skips
any conversion if the image is already in the RAW format. To
minimize the impact upon platforms that have qemu-img installed
this is being implemented by checking to see if qemu-img is
installed. If it is installed, no changes are made to the flow
through fetch_to_raw. If qemu-img is not available and the image
format is not already RAW, an exception is thrown. Otherwise,
the image is downloaded and we do not progress to the portions of
fetch_to_raw that require qemu-img to be installed.
This commit also updates the test cases that touch this code.
Fixed erroneous force full copy in ceph backup driver
The following steps should not result in a forced full copy:
1. create vol
2. create backup (works fine i.e. uses incremental diff)
3. delete backup
4. create new backup (full copy forced because volume backup-snap exists and is not ignored)
cinder.volume.rpcapi.create_volume does not convert the request_spec to
primitive before casting the request. This makes requests containing non
primitive types to fail. For example:
This will create a new database record and call create_volume on
volume.rpcapi. This will fail because VolumeMetadata won't be
serialized correctly when calling cast. This, however, is not True when
--source-volid is not passed because in such case,
scheduler.rpcpai.create_volume will be called, which converts
request_spec to primitive correctly.
