The zle compression algorithm compresses runs of zeros.
This property can also be referred to by its shortened column name
compress. Changing this property affects only newly-written data.
+ smartcompression=on|off
+ Smart compression is a feature which optimizes compression performance
+ on filesystems which contain a mixture of compressible and
+ incompressible data. When compression is enabled on a filesystem,
+ smart compression dynamically tracks per-file compression ratios to
+ determine if a file is compressible or not. When the compression ratio
+ being achieved is too low, smart compression progressively backs off
+ attempting to compress the file.
+
+ The algorithm periodically checks whether new data written to a file
+ previously deemed incompressible is still not compressible and adjusts
+ behavior accordingly. Certain types of files, such as virtual machine
+ disk files or large database files, can contain a mixture of both types
+ of data. Although smart compression tries to detect these situations,
+ in marginal cases it can be too pessimistic, which results in a
+ reduction of the overall compression ratio. In this case, setting the
+ smartcompression property to off turns off smart compression on a
+ filesystem, so that data is always compressed regardless of the
+ compression ratio achieved.
+
+ The default value is on.

sharesmb=on|off|opts
Controls whether the file system is shared via SMB, and what options

Because SMB shares requires a resource name, a unique resource name is
constructed from the dataset name. The constructed name is a copy of
the dataset name except that the characters in the dataset name, which
would be invalid in the resource name, are replaced with underscore (_)
