This patch makes a few small changes that are required in order to have the Cinder Backup service working on Windows. - all physial disks must be open in byte mode. 'rb+' must be used when writing. - reading passed the disk size boundary will not return an empty string, raising an IOError instead. For this reason, we're avoiding doing it. - we ensure that the chunk size is a multiple of the sector size. - the chmod command is not available on Windows. Although changing owners is possible, it is not needed. For this reason, the 'temporary_chown' helper will be a noop on Windows. It's easier to do it here rather than do platform checks wherever this gets called. - when connecting the volumes, we pass the 'expect_raw_disk' argument, which provides a hint to the connector about what we expect. This allows the SMBFS connector to return a mounted raw disk path instead of a virtual image path. - when the driver provides temporary snapshots to be used during the backup process, the API is bypassed. For this reason, we need to ensure that the snapshot state and progress gets updated accordingly. Otherwise, this breaks the nova assisted snapshot workflow. We're doing platform checks, ensuring that we don't break/change the current workflow. The Swift and Posix backup drivers are known to be working on Windows.
