Refactor PureISCSIDriver into base and iSCSI classes.
This adds in a new class called PureBaseVolumeDriver that contains
all of the generic shared methods that utilize the management REST API.
The PureISCSIDriver now inherits from the base driver and implements

As part of this we’ve cleaned up some of the logging where it would
previously have hard coded the drivers class name in it, and moved some
static non-class helper methods into the base class.
These changes will ease future work to add additional drivers or split
them into separate files.

Use nfs_oversub_ratio when reporting pool capacity
Currently NetApp NFS drivers do not make use of the nfs_oversub_ratio
configuration parameter to enable OpenStack administrators to report
anything other than the most conservative capacity and usage information
up to the scheduler
This commit:
* modifies the NetApp drivers to use the nfs_oversub_ratio as
documented.
* uses direct API with filers to gather capacity information rather
than stat and du commands
* brings our reporting of reserved percentage in line with the way
the scheduler actually makes use of this statistic
* simplifies and cleans up the way we gather and report pool statistics
Note that this fix addresses an in-the-field bug report from juno
and is intended to be the basis for backported fixes.
In kilo, a more general approach to overprovisioning using
max_oversubscription_ratio
was introduced via commit 3548a4bc9edbb26b248b5af5ecc2145f2c6f7481.
In this newer approach, the scheduler computes "virtual" free space
rather than the driver reporting "apparent" free space.
This fix to bring NetApp NFS drivers into conformity with the generic
NFS driver is not intended as a substitute for introducing support
in our drivers for the newer approach to overprovisioning. Rather,
it is a bug-fix for an existing failure to honor the nfs_oversub_ratio.

LVM: Pass volume size in MiB to copy_volume() during volume migration
Currently migrate_volume() in lvm.py does not pass volume size in
MiB but passes volume size in GiB to copy_volume(). The size argument
of copy_volume() requires MiB value. As a result, if the volume size
is 1GiB, copy_volume() copies only 1MiB head of 1GiB volume to the
destination volume, and then the volume data is corrupted.
This patch fixes to pass volume size in MiB.
LVM: Support efficient data copy using "dd" for create_cloned_volume
The create_cloned_volume uses dd command for data copy, but the
copy always copy full blocks even if the source data contains
many null or zero blocks. When we use thin provisioned LVM,
blocks are not pre-allocated, so unused region returns zero.
If we copy full block for destination volume, unnecessary blocks
will be allocated and the usage will be 100%.
The dd command has conv=sparse option in order to copy data more
efficiently. This patch enables conv=sparse option as an argument
of dd command for create_cloned_volume when we use thin provisioned
LVM.
[NOTE]
This patch only enables conv=sparse parameter of dd command for
create_cloned_volume() path of LVM driver. There are some places
using dd in Cinder, but we should carefully consider to apply
this parameter for other places because misuse of this parameter
causes security issues or data corruptions. Also we DO NOT use this
parameter for volume wiping case because the volume is not cleared
at all.

Check volume_backend in retype
The retype command will always attempt a call
to the driver.retype method. In *most* cases this
will hit the default impl which returns False because
most drivers don't implement any retype (most, a few do).
The problem is that the drivers that do implement this in
most cases will iterate through the settings and just make
the changes that are valid and ignore the rest, and then
return True. I think this is "ok" for the drivers to do,
drivers should be allowed to be somewhat dumb WRT Cinder
state management and placement info. If we give them an
invalid command (which we're doing here) then it's on us
higher up the chain IMO.
The result is that for example if you're trying to retype
from backend-a to backend-b and backend-a implements retype
it can return True telling the manager that the volume was
succesfully retyped, even when it wasn't.
There's a lot of confusion around this bug, YES the
filter scheduler is used to determine if the retype is
valid and to what host. That's not the issue, the issue
is that regardless of the source and destination host settings
that are provided from the filter-scheduler, we always make the
call to the driver, introducing the opportunity for a false
success status being reported back.
This patch adds a very simple check between the source and
destination host settings as provided by the scheduler and in
the case that the two are "different"(not including pool designations)
we skip calling the driver.retype method altogether and fall through
to the migrate process.
