Currently running "zfs set" without any options lists the properties which can be set for the zfs filesystem. The output is something like this:
$ /usr/sbin/zfs set
missing property=value argument
usage:
set <property=value> <filesystem|volume> ...
The following properties are supported:
PROPERTY EDIT INHERIT VALUES
type NO NO filesystem | volume | snapshot
creation NO NO <date>
used NO NO <size>
available NO NO <size>
referenced NO NO <size>
compressratio NO NO <1.00x or higher if compressed>
mounted NO NO yes | no | -
origin NO NO <snapshot>
...
It would be easier to find a property if they were listed in alphabetical order. The man page should also list the properties in alphabetical order.
