    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

    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:
