Ho lokolloa ha morero oa OpenZFS 2.1 ho phatlalalitsoe, ho nts'etsapele ts'ebetsong ea sistimi ea faele ea ZFS bakeng sa Linux le FreeBSD. Morero o ile oa tsejoa e le "ZFS ho Linux" mme pele o ne o lekanyelitsoe ho nts'etsapele mojule bakeng sa kernel ea Linux, empa kamora ts'ehetso e tsamaeang, FreeBSD e ile ea amoheloa e le ts'ebetsong ea mantlha ea OpenZFS mme ea lokoloha ho bua ka Linux ka lebitso.
OpenZFS e lekoa ka lithollo tsa Linux ho tloha 3.10 ho isa 5.13 le makala ohle a FreeBSD ho qala ho tloha 12.2-RELEASE. Khoutu e ajoa tlasa laesense ea mahala ea CDDL. OpenZFS e se e sebelisoa ho FreeBSD mme e kenyelelitsoe ho liphaello tsa Debian, Ubuntu, Gentoo, Sabayon Linux le ALT Linux. Liphutheloana tse nang le mofuta o mocha haufinyane li tla lokisetsoa kabo e kholo ea Linux, ho kenyeletsoa Debian, Ubuntu, Fedora, RHEL/CentOS.
OpenZFS e fana ka ts'ebetsong ea likarolo tsa ZFS tse amanang le tsamaiso ea faele le mookameli oa molumo. Ka ho khetheha, likarolo tse latelang li kenngoa ts'ebetsong: SPA (Storage Pool Allocator), DMU (Data Management Unit), ZVOL (ZFS Emulated Volume) le ZPL (ZFS POSIX Layer). Ntle le moo, projeke e fana ka bokhoni ba ho sebelisa ZFS joalo ka mokokotlo oa sistimi ea faele ea Luster cluster. Mosebetsi oa morero o ipapisitse le khoutu ea ZFS ea mantlha, e tsoang kantle ho projeke ea OpenSolaris mme e atolosoa ka lintlafatso le litokiso ho tsoa sechabeng sa Illumos. Morero ona o ntse o ntlafatsoa ka ho kenya letsoho ha basebetsi ba Laboratori ea Naha ea Livermore tlas'a konteraka le Lefapha la Matla la United States.
Khoutu e ajoa tlas'a laesense ea mahala ea CDDL, e sa lumellaneng le GPLv2, e sa lumelleng ho kopanngoa ha OpenZFS lekaleng le ka sehloohong la Linux kernel, kaha ho kopanya khoutu tlas'a laesense ea GPLv2 le CDDL ha ho amohelehe. Ho qoba ho se lumellane hona ha laesense, ho ile ha etsoa qeto ea ho aba sehlahisoa sohle tlas'a laesense ea CDDL e le mojule o ka jarolloang ka thoko, o fanoang ka thoko ho kernel. Ho tsitsa ha codebase ea OpenZFS ho hlahlojoa ha ho bapisoa le FS tse ling bakeng sa Linux.
