States for managing zpools
:maintainer: Jorge Schrauwen <sjorge@blackdot.be>

.. versionadded:: 2016.3.0
.. versionchanged:: 2018.3.1
Big refactor to remove duplicate code, better type converions and improved
consistancy in output.

.. warning::
The layout will never be updated, it will only be used at time of creation.
It's a whole lot of work to figure out if a devices needs to be detached, removed,
etc. This is best done by the sysadmin on a case per case basis.
Filesystem properties are also not updated, this should be managed by the zfs state module.

Turn the layout data into usable vdevs spedcification
We need to support 2 ways of passing the layout:
.. code::
layout_new:
- mirror:
- disk0
- disk1
- mirror:
- disk2
- disk3
.. code:
layout_legacy:
mirror-0:
disk0
disk1

ensure storage pool is present on the system
name : string
name of storage pool
properties : dict
optional set of properties to set for the storage pool
filesystem_properties : dict
optional set of filesystem properties to set for the storage pool (creation only)
layout: dict
disk layout to use if the pool does not exist (creation only)
config : dict
fine grain control over this state
.. note::
The following configuration properties can be toggled in the config parameter.
- import (true) - try to import the pool before creating it if absent
- import_dirs (None) - specify additional locations to scan for devices on import (comma-seperated)
- device_dir (None, SunOS=/dev/dsk, Linux=/dev) - specify device directory to prepend for none
absolute device paths
- force (false) - try to force the import or creation
.. note::
It is no longer needed to give a unique name to each top-level vdev, the old
layout format is still supported but no longer recommended.
.. code-block:: yaml
- mirror:
- /tmp/vdisk3
- /tmp/vdisk2
- mirror:
- /tmp/vdisk0
- /tmp/vdisk1
The above yaml will always result in the following zpool create:
.. code-block:: bash
zpool create mypool mirror /tmp/vdisk3 /tmp/vdisk2 mirror /tmp/vdisk0 /tmp/vdisk1
.. warning::
The legacy format is also still supported but not recommended,
because ID's inside the layout dict must be unique they need to have a suffix.
.. code-block:: yaml
mirror-0:
/tmp/vdisk3
/tmp/vdisk2
mirror-1:
/tmp/vdisk0
/tmp/vdisk1
.. warning::
Pay attention to the order of your dict!
.. code-block:: yaml
- mirror:
- /tmp/vdisk0
- /tmp/vdisk1
- /tmp/vdisk2
The above will result in the following zpool create:
.. code-block:: bash
zpool create mypool mirror /tmp/vdisk0 /tmp/vdisk1 /tmp/vdisk2
Creating a 3-way mirror! While you probably expect it to be mirror
root vdev with 2 devices + a root vdev of 1 device!
