Aus UUGRN
Jedes ZFS-Dataset hat eine Hand voll Eigenschaften.
shl@lightbulb:~$ zfs get all strangepool/justatest NAME PROPERTY VALUE SOURCE strangepool/justatest type filesystem - strangepool/justatest creation Thu Dec 3 16:06 2009 - strangepool/justatest used 19K - strangepool/justatest available 392G - strangepool/justatest referenced 19K - strangepool/justatest compressratio 1.00x - strangepool/justatest mounted yes - strangepool/justatest quota none default strangepool/justatest reservation none default strangepool/justatest recordsize 128K default strangepool/justatest mountpoint /strangepool/justatest default strangepool/justatest sharenfs off default strangepool/justatest checksum on default strangepool/justatest compression off default strangepool/justatest atime on default strangepool/justatest devices on default strangepool/justatest exec on default strangepool/justatest setuid on default strangepool/justatest readonly off default strangepool/justatest zoned off default strangepool/justatest snapdir hidden default strangepool/justatest aclmode groupmask default strangepool/justatest aclinherit restricted default strangepool/justatest canmount on default strangepool/justatest shareiscsi off default strangepool/justatest xattr on default strangepool/justatest copies 1 default strangepool/justatest version 3 - strangepool/justatest utf8only off - strangepool/justatest normalization none - strangepool/justatest casesensitivity sensitive - strangepool/justatest vscan off default strangepool/justatest nbmand off default strangepool/justatest sharesmb off default strangepool/justatest refquota none default strangepool/justatest refreservation none default strangepool/justatest primarycache all default strangepool/justatest secondarycache all default strangepool/justatest usedbysnapshots 0 - strangepool/justatest usedbydataset 19K - strangepool/justatest usedbychildren 0 - strangepool/justatest usedbyrefreservation 0 -
Genauso hat auch ein ZPool Eigenschaften:
shl@lightbulb:~$ zpool get all strangepool NAME PROPERTY VALUE SOURCE strangepool size 398G - strangepool used 137K - strangepool available 398G - strangepool capacity 0% - strangepool altroot - default strangepool health ONLINE - strangepool guid 9643469012468915043 default strangepool version 14 default strangepool bootfs - default strangepool delegation on default strangepool autoreplace off default strangepool cachefile - default strangepool failmode wait default strangepool listsnapshots off default
Diese Eigenschaften können mit zfs set $foo=$bar bzw. zpool set $foo=$bar gesetzt werden.
Beispiel:
shl@lightbulb:~$ pfexec zfs set compression=on pool/dataset
Alle gesetzten Attribute vererben sich nach unten in der Hierarchie. Das oben genannte Beispiel schaltet die Kompression für alle Datasets unterhalb von pool/dataset ein.
