Various commands were failing when running multiple copies of
cinder-volume. This is due to storing an in memory copy of the luns
which may get updated in the backend by another cinder-volume. Fix
it by attempting to refresh the list of luns if one is not found
during a request.
Introduces a volume driver which makes use of SMB shares for
hosting volumes as disk images, having a similar workflow with the
other NFS like drivers.
The driver uses Samba in order to access the SMB shares. It takes
SMB shares information such as share path, credentials and other
mount flags from a config file of which location can be configured
in the cinder config file.
It includes all the features required by the Juno release.
Given the non-blocking nature of RPC cast, what happens in volume
manager and volume driver can happen in parallel with the DB update.
If volume driver relies on original DB record to do things, then
DB record shouldn't be updated until volume driver finishes its job.
So this patch change volume RPC API accept_transfer() from cast
to call to make sure the workflow is in serialized manner. Also
elevated the context when volume manager tries to update the DB
record when driver has done accept_transfer().
This patch changes the glance client version unit tests
to mock the Client object completely. Previously the
tests were ensuring the right version of the client was
returned, but that required too much knowledge of glance's
implementation and ended up breaking the tests when glance
changed the implementation details of the Client class.
The new code tests if cinder is calling the integration
point correctly for the version, rather than if glance
is correctly returning the right client; that should be
a glance test, not a cinder test.

Pool-aware Scheduler Support
This change introduces pool-aware scheduler to address the need for
supporting multiple pools from one storage controller.
Terminology
-----------
Pool - A logical concept to describe a set of storage resource that
can be used to serve core Cinder requests, e.g. volumes/snapshots.
This notion is almost identical to Cinder Volume Backend, for it
has simliar attributes (capacity, capability). The main difference
is Pool couldn't exist on its own, it must reside in a Volume
Backend. One Volume Backend can have mulitple Pools but Pools
don't have sub-Pools (meaning even they have, sub-Pools don't get
to exposed to Cinder, yet). Pool has a unique name in backend
namespace, which means Volume Backend can't have two pools using
same name.
Legacy Volume - Volumes that were created prior pools are introduced.
There are several corner cases where legacy volumes could cause
issues, especially for those drivers used to do pools internally
(e.g. 3Par, NetApp). Please refer to 'Limitation/Known Issues' for
details.
Design
------
The workflow in this change is simple:
1) Volume Backends reports how many pools and what those pools
look like and are capable of to scheduler;
2) When request comes in, scheduler picks a pool that fits the need
most to serve the request, it passes the request to the backend
where the target pool resides in;
3) Volume driver gets the message and let the target pool to serve
the request as scheduler instructed.
To support placing resources (volume/snapshot) onto a pool, these
pieces in Cinder currently are missing:
1. Volume Backends reporting capacity/capabilities at pool level;
2. Scheduler filtering/weighing based on pool capacity/capability
and placing volumes/snapshots to a pool of certain backend;
3. Record which pool a resource is located on a backend and passes
between scheduler and volume backend.
The missing piece 1 is solved by a) updating the format of
periodical volume stats message to adopt pool stats; b) altering
manager/driver to collect and report pool stats. Below is an example
of the updated report message that contains 2 pools:
Notice that there are now two levels of mandatory/fixed stats &
capabilities that every volume driver should report.
The scheduler change is mostly done in scheduler/host_manager.py:
* HostState adds a list element to hold PoolState(s) (a HostState sub-
class). Each PoolState can be treated like a HostState since it has
as much information as HostState and also share the same structure.
HostState.update_capabilities()/update_from_volume_capability() are
changed to handle both legacy and new report messages.
* HostManager.get_all_host_states() now returns a PoolState iterator
that includes all pools scheduler tracks. To filters and weighers,
PoolState() and HostState() are identical, thus there is no need to
change filters and weighers since they are dealing with same kind of
information and exact same data strucuture as before. What filter
and weigher deals with looks like this:
# Before this change
HostState() for Backend 1
...
HostState() for Backend N
# After this change
PoolState() for Backend 1 Pool 1
...
PoolState() for Backend 1 Pool N
...
PoolState() for Backend N Pool 1
...
PoolState() for Backend N Pool N
With this change, filter scheduler will pick a pool@host instead of a
host.
Now that we are able to report and decide at pool level, the 3rd
missing piece is easy to fix. Just like how multi-backend
volume service is supported, we encoded pool name into 'host' field
of Volume table. The 'host' field is now 'host@backend#pool'. Notice
that this change doesn't mean that cinder-volume service will have to
subscribe to multiple RPC channels. There is no need to mess with
message queue subscription at all because we did a little trick when
determining RPC target in VolumeRPCAPI: correct host info like
'host@backend' is extracted from 'host@backend#pool' before sending
RPC messages. Therefore, once scheduler decides which pool on a
backend shall serve a request, it updates 'host' field of the volume
record in DB to be like 'host@backend#pool', but it still sends RPC
message to 'host@backend' which cinder-volume is listening to.
Simliar action is done when creating backups for volumes. host@backend
is extracted from volume['host'] so that correct backup service can be
picked.
Other changes are done in this patch:
* Change get_volume_stats() in ISCSIVolumeDriver/ISERDriver to include
pool stats, and change default total/free_capacity_gb from 'infinite'
to 0.
* Add logic in volume manager init_host() to detect legacy volumes and
try to update host info for them if driver is able to provide pool info.
* Add get_pool() driver API to return the pool name of given volume,
this help volume manager to handle legacy volumes, especially for those
backends already support pooling internally (e.g. 3Par, NetApp).
* Implement get_pool() for LVM driver to return volume backend name as
pool name.
* Add extract_host() helper function in cinder/volume/utils.py to help
handle cases where there is needs to extract 'host', 'backend' or
'pool' information from volume['host'].
* Add append_host() helper function in cinder/volume/utils.py to help
concatenate host and pool string into one for volume['host'] field.
Limitation/Known Issues
-----------------------
* The term 'host' in Cinder used to refer to 'backend', and it was
consistent from the view of end users/admins to Cinder internals.
Now that pool is exposed to Cinder scheduler, scheduler starts treating
different pools on same backend as different hosts. Therefore, we have
to expose pool to admin at least, because migrating volume now has to
include pool in 'host' parameter in order to work. As for end users,
the whole 'host' of volume equals storage backend idea works well for
them, so they can decide the policy of migration when retyping volumes,
or choose to create new volume on same or different host as/from
existing volumes. Now it's *not* easy to hide pool from end user and
make retype or affinity filter work like before. This change has a
speical code path for legacy volumes, to allow (potential) migration
between pools even migration_policy is set to 'never'. But not every
driver has magic to move volumes to one pool to another at minimum
cost. The inconsistency behavior between drivers (same command may
take totally different time to finish), which could be very confusing.
* Drivers want to support pools need to update, but they should work
just like they used to without any change except:
- creating volume using same/different host hints with legacy volumes
may NOT work as expected, because 'hostA' is considered different
from 'hostA#pool0' and 'hostA#pool1'. But legacy volume on 'hostA'
might actually resides in pool0, only the driver has this knowledge.
- retyping legacy volume issue as mentioned above.
Ultimate solution for all these corner cases is to update Cinder DB
to add 'pool' info for legacy volumes. The problem is only the driver
knows such info, that is why we add a new driver API get_pool() to
so that volume manager is able to learn pool info from driver and
update host field of legacy volumes in DB.
User-Visible Change
-------------------

information as part of host string. For example:

Consistency Groups
This patch enables Consistency Groups support in Cinder.
It will be implemented for snapshots for CGs in phase 1.

------------------------------------------------
The workflow is as follows:
1) Create a CG, specifying all volume types that can be supported by this

The CG will be empty when it is first created. Backend needs to report
consistencygroup_support = True. Volume type can have the following in
extra specs: {'capabilities:consistencygroup_support': '<is> True'}.
If consistencygroup_support is not in volume type extra specs, it will be
added to filter_properties by the scheduler to make sure that the scheduler
will select the backend which reports consistency group support capability.
This will add a cgsnapshot entry in the new cgsnapshots table, create
snapshot for each volume in the CG, and add a cgsnapshot_id foreign key
in each newly created snapshot entry in the db.
