New in version 2016.3.0.
Changed in version 2018.3.1: Big refactor to remove duplicate code, better type conversions and improved consistency in output.

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.
absent(name, export=False, force=False)¶
ensure storage pool is absent on the system
name of storage pool
export instead of destroy the zpool if present
force destroy or export
present(name, properties=None, filesystem_properties=None, layout=None, config=None)¶
ensure storage pool is present on the system
name of storage pool
optional set of properties to set for the storage pool
optional set of filesystem properties to set for the storage pool (creation only)
disk layout to use if the pool does not exist (creation only)
fine grain control over this state
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
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.
- mirror: - /tmp/vdisk3 - /tmp/vdisk2 - mirror: - /tmp/vdisk0 - /tmp/vdisk1
The above yaml will always result in the following zpool create:
zpool create mypool mirror /tmp/vdisk3 /tmp/vdisk2 mirror /tmp/vdisk0 /tmp/vdisk1
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.
mirror-0: /tmp/vdisk3 /tmp/vdisk2 mirror-1: /tmp/vdisk0 /tmp/vdisk1
Pay attention to the order of your dict!
- mirror: - /tmp/vdisk0 - /tmp/vdisk1 - /tmp/vdisk2
The above will result in the following zpool create:
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!
