Make sure device support Direct before setting
We added '-t none' option to the qemu-img convert operation
in image_utils.py a while back to accomodate a couple of
backend devices that didn't flush writes on disconnect.
(Change: I7a04f683add8c23b9125fe837c4048ccc3ac224d)
The only problem here is that some backend devices don't
support Direct mode and raise an exception and fail when
setting this option.
This patch adds a simple check using dd to see if the dest
supports the Direct flag and only sets '-t none' if the device
does in fact support it.
Additionally it was brought up that even yet other backends
are using file devices not blk devices. In their case setting
Direct will still work, however it's sub-optimal as qemu-convert
has internal mechanisms to make sure flushing etc are done
correctly and efficiently for those devices. So to accomodate
that particular use case I'm also adding a check if blk dev
that can be used for determining whether to set Direct for the
qemu-convert process.
Windows SMBFS: Handle volume_name in _qemu_img_info
The volume_name is now parsed to the _qemu_img_info wrapper. As
this method is not prone to security issues because this driver
does not support raw images (at least not yet), we don't have to
perform any checks on the backing image file path.
Thus, this method simply ignores this argument that will be parsed
by the base class methods.

Fix unnecessary WSGI worker warning at API startup
There was a bug in WSGIService in the way that it was

however, never happened because getattr interpreted the default

Downgrade 'infinite' and 'unknown' capacity in weigher
When FilterScheduler was first introduced into Cinder, drivers were
required for the first time to report capacity. Some drivers preferred
to report 'infinite' or 'unknown' capacity because they were doing
thin-provisioning or the total capacity kept increasing. Now that we
have better support for thin-provisioning and we do find unrealistic
capacity couldn't do us any good in making optimal scheduling decision,
because 'infinite' and 'unknown' would always have the highest weight
when the weight multiplier is positive, which in most cases it is.
Drivers are expected to avoid sending 'infinite' 'unknown' capacity
anymore, instead, should report an actual real number for total/free
capacity.
This fix doesn't fix the driver, instead a small tweak is added to
CapacityWeigher in order to downgrade those drivers who report
'infinite' or 'unknown' as free capacity. In particular, those who
report 'infinite'/'unknown' free capacity will be adjusted to be the
one has lowest weight, no matter in 'spreading' (weight multiplier>0)
or 'stacking' (weight multiplier<0) mode.

DB migration 25->24 failed when dropping column
"cinder-manage db sync 24" failed when dropping column cgsnapshot_id
from the snapshots table.
The reason that drop column failed was because of the foreign key
constraint. MySQL cannot drop column until the foreign key constraint
is removed. So the solution is to remove the foreign key first, and
then drop the column. This affects the cgsnapshot_id column in the
snapshots table and the consistencygroup_id column in the volumes table.
With pool support added to Cinder, now we are kind of in an awkward
situation where we require admin to input exact location for volumes
to-be managed (imported) or migrated, which must have pool info, but
there is no way to find out what pools are there for backends except
looking at the scheduler log. That causes bad user experience, and
thus is a bug from UX POV.
This change simply adds a new admin-api extension to allow admin to
fetch all the pool information from scheduler cache (memory), which
closes the gap for end users.
This extension provides two level of pool information: names only or
detailed information:
Pool name only:
GET http://CINDER_API_ENDPOINT/v2/TENANT_ID/scheduler-stats/get_pools
Detailed Pool info:

HP 3PAR: Allow retype when the old snapshot CPG (3PAR pool) is None
A common provisioning group (CPG) is a virtual pool of logical disks.
A volume is stored in a CPG. The volume's snapshots may be stored in
the same CPG or in a separate CPG. In 3PAR this is the "snapCPG".
Before the 3PAR driver supported "manage", the snapCPG was never None in
OpenStack because when we create volumes, we explicitly default snapCPG
to match the volume CPG unless otherwise specified. So, the original
retype pre-checks raised an exception if this unexpected case occurred
and a unit test was provided for that exception.
Now that we support manage_existing(), it should be a valid use case
to manage an existing volume created outside of OpenStack with a snapCPG
set to None. Unfortunately, when we applied volume-type settings to this
volume we would hit that old exception.
That exception has been removed.
Removing it required the following changes:
1. When retype pre-checks validate the domain of the new snapCPG, it
will not use the optional old snapCPG. Instead it will compare the
new snapCPG domain with the old volume CPG domain. This satisfies
the requirement that domains cannot be mixed and avoids the need
to have an old snapCPG setting.
2. Remove the no longer used old_snap_cpg parameter and remove the
code that raised an exception "if not old_snap_cpg".
3. Remove the unit test that was just to test that obsolete exception.
4. Adjust the exiting test_retype_across_snap_cpg_domains to
verify that a snapCPG domain that does not match the volume
CPG domain will still raise Invalid3PARDomain
This patch adds support for retype operation in the VMDK driver.
The VMDK driver uses the extra spec keys 'vmware:vmdk_type' and
'vmware:storage_profile' to determine the disk provisioning type
and storage policy of the backing VM. Currently it is not possible
to change the disk provisioning type or storage policy after volume
creation. With retype support, user can change the disk provisioning
type and storage policy by changing the volume's type to another type
with extra spec keys set to desired values.
The current datastore selection logic is not modularized and difficult
to extend. The retype API implementation has a requirement to specify
hard anti-affinity requirement with the current backing datastore. Some
of the bug fixes also need to specify hard affinity with one or more
datastore types. To support such requirements and to enable future
extensions, this patch introduces a new module which contains datastore
selection logic. The existing code for datastore selection is reused as
much as possible. The dependency on existing datastore selection logic
will be removed in a separate patch.
The current datastore selection iterates over a list of hosts, for each
host, queries the connected valid datastores and tries to select a
suitable datastore. The filtering is based on space, storage profile,
number of connected hosts and space utilization. The space utilization
is used only for breaking ties. If a suitable datastore is found, further
processing of list of hosts is skipped, which could result in uneven space
utilization. To solve this, the new selection logic introduces a requirement
called 'preferred_utilization_threshold' which can be exposed as a driver
config option.
