In vCenter inventory, volumes are organized under the folder:
<datacenter_vm_folder>/<volume_folder>, where <volume_folder>
is the value of driver config option 'vmware_volume_folder'.
Due to this organization certain project-specific maintenance
tasks (using vSphere client) might be difficult for vCenter
admin. For example, the admin may need to migrate the volumes
of a particular project from one vCenter datastore to another.
This patch changes the folder hierarchy to:
<datacenter_vm_folder>/OpenStack/Project
(<project_id>)/<volume_folder>
for better organization.
DocImpact
Modified default value of config option
'vmware_volume_folder' and updated its description.

3PAR: Adding performance metrics to volume status
If one storage backend has high load while another has lower load,
when a user/admin creates a volume, the current evaluator/scheduler
may place the volume on the backend with higher load. In many cases,
the evaluator/scheduler should place that volume on the backend
with the lowest load for load balancing purposes. In general, for load
balancing virtual volume placement, an evaluator/scheduler needs
access to performance metrics (e.g. IOPS throughput, bandwidth,
latency, IO size) to measure load, but Cinder drivers don't generally
report those metrics.
Although these performance metrics are available from the 3PAR CLI,
they are currently inaccesible in the evaluator/scheduler. The
proposed changes add these metrics to the volume status report and
thus make them accesible by the evaluator/scheduler.
In cinder/volume/drivers/san/hp/hp_3par_common.py, uses the 3PAR
client method HP3parClient.getCPGStatData to get performance metrics,
and adds new fields in the output of HP3PARCommon.get_volume_stats
corresponding to the performance metrics: IOPS throughput, bandwidth,
latency, io_size, queue_length, and avg_busy_perc. These metrics are
taken by averaging samples taken once per day for the last week.
In cinder/tests/unit/test_hp3par.py, adds unit tests in
TestHP3PARFCDriver.test_get_volume_stats and in
TestHP3PARISCSIDriver.test_get_volume_stats.

Don't use context.elevated to get volume
Original Problem:
=================
Since the metadata(readonly and attached_mode) is stored in admin metadata,
normal user need `run context.elevated` to retrieves admin metadata.
The above way will bring a side effect. Normal user can also get
any volume which the user shouldn't access when the user knows the UUID.
Solution:
=========
Use context instead of context.elevated to get volume.
And add admin metadata to it.
Based on cinder-meetup-summer-2015 conclusion, we use the solution.
The solution will need extra database connection.

Enable cinder-manage to remove services
These changes are to enable cinder-manage to remove old services

method to manage.py and tests to cover this new method in test_cmd.py.
The command will remove the binary from the list of running services
in the db that can be viewed via "cinder-manage service list". NOTE:
Active and restarted services will re-populate the DB with their current

To use this new command, the user types "cinder-manage service remove

On Volume list only retrieve needed data from DB
Currently when there is no limit set on a volume list query we retrieve
all volumes and then limit them locally using osapi_max_limit. Similar
thing happens when we are using the marker for next pages, we get all
volumes from that marker until the last volume and then limit it
locally.
We should be limiting it on the DB side so we only retrieve the data we
are actually going to return to the API caller.
This patch always limits the data retrieved from the DB and for the
offset to keep working as it was before we need to do the offset on the
DB side as well.
For reference some tests were performed:
On a deployment with 60,000 volumes, 370,000 volume_metadata items and
240,000 volume_glance_metadata items in cinder db. Before the patch
this will use nearly 10G memory. With the patch we will just use about
500M.
This patch changes the way we handle volume detach
attempts when the attachment_id is already detached
and/or when the volume has no attachments. We now
handle this the same way we do with deleting volumes
that don't exist. We return success.
This patch also takes care to make sure we safely reset
the volume status to what it should be depending on if
there are other attachments. If the attachment_id is
passed in and that attachment is detached, but there are
other attachments, we want to make sure that the volume is
left in an in-use state, not available.

Remove RetypeVD class, fix NFS driver retype
retype() only exists in the deprecated VolumeDriver() class
and not BaseVD. This means that drivers inheriting from *VD
hit attribute errors when trying to call driver.retype().
The thinking here is that RetypeVD isn't really necessary,
since all drivers must implement some version of the retype
method (even if it's a no-op with just a standard return code).
Therefore, just rely on this being in the base driver class(es)
rather than making it a separate abc class.

GPFS volume encryption-at-rest support
This patch extends the capability of gpfs driver to support volume encryption
at rest using GPFS Native Encryption feature (https://ibm.biz/BdXPBm).
This includes:
1. Verification of configured gpfs backend to support encryption at rest.
2. Driver exposes gpfs_encryption_rest capability via volume type convention.
Usage - Cloud admin creates a volume type "encrypted" with extra-specs
gpfs_encryption_rest=True
Every volume created using type "encrypted", the volumes will be encrypted
at rest.
DocImpact
Needs an update in gpfs driver documentation, as this patch introduces
encrypted backend support.
The symlinks in /dev/disk/by-id/ (in a Linux guest OS running in VMware
ESX based Nova instance) use UUID of virtual disk as the SCSI device ID
when disk.EnableUUID is set to True in the virtual machine configuration
file. This patch sets the UUID of virtual disk corresponding to a Cinder
volume (at the time of volume creation) to volume ID so that end-users
(of Nova instance) can identify the device corresponding to an attached
volume in the guest using /dev/disk/by-id symlink.
For example, given a Cinder volume with ID = xyz, user can identify the
device corresponding to the volume in instance's guest using the symlink
/dev/disk/by-id/scsi-xyz provided disk.EnableUUID is set to True in the
instance's virtual machine configuration file (in ESX).
Note: If the UUID of the virtual disk corresponding to a volume is unset
at the time of volume creation, a random UUID will be used.
There are test cases that require oslo.vmware and the change made in the
commit for tox doesn't cover the case where run_tests.sh is used. Without
including oslo.vmware in the test-requirements file there are a number of
test cases that fail without the library installed.
This patch resolves the issue by move oslo.vmware over to the
test-requirements file.

Prevent creating encrypted volume with image
When creating an encrypted volume with a unencrypted image,
cinder just copies the unencrypted data to the volume,
which keeps unencrypted data in the volume.
But when booting/attaching the volume to Nova, it thinks
encrypted data on the volume. As a result, Nova reads
the data incorrectly.
The fix is to prevent such action. Later, we can
implement to write encrypted data in encrypted volumes
when creating from unencrypted image.
