Enables or disables barriers for mounts according to the value of the
boolean option [option]`disable_barriers`. The option additionally allows
the special value `force`, which disables barriers even on mountpoints with
write back caches.
NOTE: Only extended file systems (ext) are supported by this plug-in.

Gets the information about disks, partitions and mountpoints. Stores information about used filesystem and
creates a list of all underlying devices (in case of LVM) for each mountpoint.
