 * Expand file system
 * Unmount file system
+=== Mount options ===
+The default mount settings chosen by btrfs are really optimal in most cases! There are only a few options to think about. Current and accurate information can also be found at: https://btrfs.readthedocs.io/en/latest/Administration.html
+* '',discard'' ('''automatic !)'''
+* '',ssd'' ('''automatic !)'''
+* '',space_cache'' ('''automatic !)'''
+* ''''',compress=zstd:7'''''
+Enables automatic and transparent compression in the file system. If compression is enabled, nodatacow and nodatasum are disabled.
+Btrfs makes the compression level adjustable, with higher levels trading off speed and memory for higher compression rates. ZLIB accepts the range [1, 9] and ZSTD accepts [1, 15]. Default is 3 each
+* ''''',noatime'''''
+Under read intensive work-loads, specifying noatime significantly improves performance because no new access time information needs to be written. Without this option, the default is ''relatime''. (This may be combined with ''''',lazytime''''')
