If invalid 'attachment_id' is passed to the os-detach

VolumeAttachmentNotFound exception is raised from manager,
it gets converted to RemoteError due to rpcapi call.

Logging not using oslo.i18n guidelines (zonemgr)
Multi-patch set for easier chunks. This one addresses
the zonemanager cinder directory.
There have been quite a few instances found where the
i18n guidelines are not being followed. I believe this
has helped lead to some of the confusion around how to
correctly do this. Other developers see this code and
assume it is an example of the correct usage.
This patch attempts to clean up most of those violations
in the existing codebase to hopefully help avoid some of
that confusion in reviews.
Some issues address:
* Correct log translation markers for different log levels
* Passing format values as arguments to call, not preformatting
* Not forcing translation via six.text_type and others
Guidelines can be found here:
http://docs.openstack.org/developer/oslo.i18n/guidelines.html
Hacking checks will not be able to identify all violations of
the guidelines, but it could be useful for catching obvious
one such as LOG.info("No markers!").

and contain only necessary information. Debug output should not be mixed
with tests output.

Fix range check for NFS used ratio
The nfs_used_ratio configuration parameter is supposed to be
greater than zero and less than or equal to one. However,
current configuration checks actually allow values greater
than one because of a logic error. Unit tests fail to detect
this issue because they find the exception that they expect
to find, but it is actually being thrown for another reason.
This commit fixes the logic error in the nfs driver code.
It also reworks all the unit tests for the do_setup method since
they suffer from the same issue that led to failure to detect
this error in the first place - they fail to do proper mocks of
submethods, and when these run the expected exception gets triggered
for the wrong reason. We have moved these tests into their own test
class, where mock is used rather than mox. Over time it is likely
that new tests will be implemented, or old tests reworked, with mock
instead of mox. These can go in the new test class, which can be
renamed if that is appropriate.
When attach is called twice for the same volume and instance the
attach_volume checks if the attachment already exists and returns.
This leaves the volume in 'Attaching' state. The volume status should

Add test case for volume_encryption_metadata_get
This change adds unit tests for the volume_encryption_metadata_get

refactoring this code as part of follow-up patches.
Writing the unit tests also exposed a minor issue with the existing
implementation of the volume_encryption_metadata_get function. If the
volume type is not encrypted, then the existing implementation would
raise an exception due to volume_type_encryption_get returning None.
In practice, this issue would not be encountered due to separate
checks to ensure that the volume type is encrypted, but a small
refactoring obviates the need for these checks and allows the
volume_encryption_metadata_get function to be invoked for both
encrypted and "normal" volumes.
A separate patch will clean up the unnecessary checks to ensure that
the volume type was encrypted prior to calling this function.

Enable use of filter_function in PureISCIDriver
Adding filter_function to capabilities of PureISCIDriver. Return
total_volumes as well for use with filter_function.
This will open a way for admins to prevent Cinder from scheduling
volumes on a Pure backend once it has reached the array’s limits. The
primary use case for this is volume limits. An example of a
filter_function that will prevent this issue would be:
This will prevent any issues with Purity versions that are limited to
500 volumes.
Without that filter_function the scheduler will continue to try and
schedule volume creation if space is available instead of selecting
another backend. The end result would be volume creation fails and the
volume is in an error state even though there are backends available
that could have handled it.

off of need to be added to the driver config manual.

NetApp E-Series: Fix instance live-migration with attached volumes
Currently, live migrations of instances with attached volumes that live

guest. This patch adds the 'netapp_enable_multiattach' configuration
option that enables multiattach operations with the E-Series driver.
It defaults to allowing these operations but needs to be configurable
since allowing for multiple attachments imposes a limit of 256 volumes
on the backend due to how multiple attachments must be managed by
E-Series.
Multiattach operations are enabled by mapping volumes to an E-Series
host group on the backend called 'cinder-host-group'. Host groups can
only have 256 mappings at a time and so we must limit the number of
volumes in order to guarantee any volume created could then be attached.

Remove force check from copy_volume_to_image
The upload_volume_to_image method allows a force parameter that will
upload a volume even though the volume is attached/in-use. A user can
get away with this with the LVM driver because the LVM backing is
local to the Cinder worker node that's pushing the bits to Glance.
The problem is, this only works for local storage, it won't work
with any iSCSI devices because they can't do multi-attach. Also,
the reason we required that a volume NOT be in-use for this
operation is because we have no way of keeping the guest Instance
from writing to the volume while we're uploading, and corrupting the data.

disable), and deployers can choose whether they would like to
