Het opensource zfs-bestandssysteem is oorspronkelijk door Sun ontwikkeld voor Solaris, maar in 2013 heeft een aantal ontwikkelaars OpenZFS opgericht om de verdere ontwikkeling te waarborgen. Het bestandssysteem wordt momenteel officieel ondersteund op Linux en FreeBSD. Het bevat onder andere methodes om datacorruptie in zowel de data als de metadata te voorkomen, biedt dataredundantie via RAID-Z en bespaart ruimte door de data transparant te comprimeren. Voor meer informatie verwijzen we jullie door naar de OpenZFS-website. De changelog voor versie 2.2.11 kan hier worden gevonden, voor versie 2.3.8 staat het hier en in versie 2.4.4 zijn de volgende veranderingen en verbeteringen aangebracht:
