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> quota YES NO <size> | none reservation YES NO <size> | none volsize YES NO <size> volblocksize NO NO 512 to 128k, power of 2 recordsize YES YES 512 to 128k, power of 2 mountpoint YES YES <path> | legacy | none sharenfs YES YES on | off | share(1M) options checksum YES YES on | off | fletcher2 | fletcher4 | sha256 compression YES YES on | off | lzjb atime YES YES on | off devices YES YES on | off exec YES YES on | off setuid YES YES on | off readonly YES YES on | off zoned YES YES on | off snapdir YES YES hidden | visible aclmode YES YES discard | groupmask | passthrough aclinherit YES YES discard | noallow | secure | passthrough Gavin
