btrfs.subvolume_delete
Delete the subvolume(s) from the filesystem
The user can remove one single subvolume (name) or multiple of
then at the same time (names). One of the two parameters needs to
specified.
Please, refer to the documentation to understand the implication
on the transactions, and when the subvolume is really deleted.
Return True if the subvolume is deleted, False is the subvolume
was already missing.

generation_cmp
List subvolumes in the filesystem that its generation is >=,
<= or = value. '+' means >= value, '-' means <= value, If
there is neither '+' nor '-', it means = value
ogeneration_cmp

sort
List subvolumes in order by specified items. Possible values:

You can add '+' or '-' in front of each items, '+' means
ascending, '-' means descending. The default is ascending. You
can combite it in a list.
CLI Example:
salt '*' btrfs.subvolume_list /var/volumes/tmp
salt '*' btrfs.subvolume_list /var/volumes/tmp path=True
salt '*' btrfs.subvolume_list /var/volumes/tmp sort='[-rootid]'
btrfs.convert
Convert ext2/3/4 to BTRFS. Device should be mounted.
Filesystem can be converted temporarily so the further processing and rollback is possible,
or permanently, where previous extended filesystem image gets deleted. Please note, permanent
conversion takes a while as BTRFS filesystem needs to be properly rebalanced afterwards.
General options:
* **permanent**: Specify if the migration should be permanent (false by default)
* **keeplf**: Keep ``lost+found`` of the partition (removed by default,
but still in the image, if not permanent migration)
CLI Example:
salt '*' btrfs.convert /dev/sda1
salt '*' btrfs.convert /dev/sda1 permanent=True

CLI Example:
salt '*' btrfs.delete /mountpoint /dev/sda1 /dev/sda2

Create a snapshot of a source subvolume
source
Source subvolume from where to create the snapshot
dest
If only dest is given, the subvolume will be named as the
basename of the source
name

* **bytecount**: Specify the size of the resultant filesystem.
* **nodesize**: Node size.
* **leafsize**: Specify the nodesize, the tree block size in which btrfs stores data.
* **noforce**: Prevent force overwrite when an existing filesystem is detected on the device.
* **sectorsize**: Specify the sectorsize, the minimum data block allocation unit.
* **nodiscard**: Do not perform whole device TRIM operation by default.
* **uuid**: Pass UUID or pass True to generate one.
Options:
* **dto**: (raid0|raid1|raid5|raid6|raid10|single|dup)
Specify how the data must be spanned across the devices specified.
* **mto**: (raid0|raid1|raid5|raid6|raid10|single|dup)
Specify how metadata must be spanned across the devices specified.
* **fts**: Features (call ``salt <host> btrfs.features`` for full list of available features)
