* Added win_partition module

* Fixes sanity tests

* Requested changes minus changes in partition_size

* Removed trailing whitespace and fixed docstring

* Changes to parititon_size to allow variable units

* Stricter regex for partition_size

module: win_partition
version_added: '2.8'
short_description: Creates, changes and removes partitions on Windows Server
description:
- The M(win_partition) module can create, modify or delete a partition on a disk
options:
state:
description:
- Used to specify the state of the partition. Use C(absent) to specify if a partition should be removed
and C(present) to specify if the partition should be created or updated.
type: str
choices: [ absent, present]
default: present
drive_letter:
description:
- Used for accessing partitions if I(disk_number) and I(partition_number) are not provided.
- Use C(auto) for automatically assigning a drive letter, or a letter A-Z for manually assigning a drive letter to a new partition.
If not specified, no drive letter is assigned when creating a new partition.
type: str
disk_number:
description:
- Disk number is mandatory for creating new partitions.
- A combination of I(disk_number) and I(partition_number) can be used to specify the partition instead of I(drive_letter) if required.
type: int
partition_number:
description:
- Used in conjunction with I(disk_number) to uniquely identify a partition.
type: int
partition_size:
description:
- Specify size of the partition in B, KB, KiB, MB, MiB, GB, GiB, TB or TiB. Use -1 to specify maximum supported size.
- Partition size is mandatory for creating a new partition but not for updating or deleting a partition.
- The decimal SI prefixes kilo, mega, giga, tera, etc., are powers of 10^3 = 1000. The binary prefixes kibi, mebi, gibi, tebi, etc.
respectively refer to the corresponding power of 2^10 = 1024.
Thus, a gigabyte (GB) is 1000000000 (1000^3) bytes while 1 gibibyte (GiB) is 1073741824 (1024^3) bytes.
type: str
read_only:
description:
- Make the partition read only, restricting changes from being made to the partition.
type: bool
active:
description:
- Specifies if the partition is active and can be used to start the system. This property is only valid when the disk's partition style is MBR.
type: bool
hidden:
description:
- Hides the target partition, making it undetectable by the mount manager.
type: bool
offline:
description:
- Sets the partition offline.
- Adding a mount point (such as a drive letter) will cause the partition to go online again.
required: no
type: bool
mbr_type:
description:
- Specify the partition's MBR type if the disk's partition style is MBR.
- This only applies to new partitions.
- This does not relate to the partitions file system formatting.
type: str
choices: [ fat12, fat16, extended, huge, ifs, fat32 ]
gpt_type:
description:
- Specify the partition's GPT type if the disk's partition style is GPT.
- This only applies to new partitions.
- This does not relate to the partitions file system formatting.
type: str
choices: [ system_partition, microsoft_reserved, basic_data, microsoft_recovery ]
notes:
- A minimum Operating System Version of 6.2 is required to use this module. To check if your OS is compatible, see
U(https://docs.microsoft.com/en-us/windows/desktop/sysinfo/operating-system-version).
- This module cannot be used for removing the drive letter associated with a partition, initializing a disk or, file system formatting.
- Idempotence works only if you're specifying a drive letter or other unique attributes such as a combination of disk number and partition number.
- For more information, see U(https://msdn.microsoft.com/en-us/library/windows/desktop/hh830524(v=vs.85).aspx).
