Projekt je postao poznat kao &#171;ZFS on Linux&#187; i ranije je bio ograni\u010den na razvoj modula za Linux jezgru, no nakon spajanja s kodom iz FreeBSD-a, priznat je kao glavna realizacija OpenZFS i preimenovan.     <\/p>\n<p>Rad OpenZFS-a provjeren je s Linux jezgrama od 4.18 do 6.18 i svim granama FreeBSD-a, po\u010dev\u0161i od 13.3. Kod se distribuira pod slobodnom licencom CDDL. OpenZFS se ve\u0107 koristi u FreeBSD-u i dio je distribucija Debian, Ubuntu, Gentoo, NixOS i ALT Linux. Paketi s novom verzijom uskoro \u0107e biti pripremljeni za glavne distribucije Linux-a, uklju\u010duju\u0107i Debian, Ubuntu, Fedora, RHEL\/CentOS.      <\/p>\n<p>OpenZFS pru\u017ea implementaciju komponenti ZFS-a, povezanih kako s radom datote\u010dnog sustava, tako i s funkcioniranjem upravitelja volumena. Implementirane su komponente: SPA (Storage Pool Allocator), DMU (Data Management Unit), ZVOL (ZFS Emulated Volume) i ZPL (ZFS POSIX Layer). Projekt tako\u0111er omogu\u0107uje kori\u0161tenje ZFS-a kao backend-a za klaster datote\u010dnog sustava Lustre. Radna postignu\u0107a OpenZFS-a temelje se na izvornoj ZFS kodu, uvezenoj iz projekta OpenSolaris, pro\u0161irenoj pobolj\u0161anjima i ispravkama zajednice Illumos. Projekt se razvija uz sudjelovanje zaposlenika Livermore nacionalne laboratorije prema ugovoru s Ministarstvom energetike SAD-a.    <\/p>\n<p>Kod se distribuira pod slobodnom licencom CDDL, koja nije kompatibilna s GPLv2, \u0161to sprje\u010dava integraciju OpenZFS-a u glavnu granu Linux jezgre, jer mije\u0161anje koda pod GPLv2 i CDDL licencama nije dopu\u0161teno. Da bi se zaobi\u0161la licencna nekompatibilnost, odlu\u010deno je da se proizvod za Linux distribuira potpuno pod CDDL licencom kao odvojeni modul koji se isporu\u010duje odvojeno od jezgre. Stabilnost kodne baze OpenZFS procijenjena je kao usporediva s drugim FS-ovima za Linux.     <\/p>\n<p>Glavne promjene:  <\/p>\n<ul>\n<li class=\"l\"> Implementirana je mogu\u0107nost postavljanja zadanih kvota za korisnike, grupe i projekte. U prethodnim verzijama kvote su se mogle postavljati samo pojedina\u010dno za svaki identifikator korisnika. U novoj verziji je uvedena mogu\u0107nost postavljanja zadane vrijednosti koja \u0107e se primijeniti ako za odre\u0111enog korisnika kvota nije postavljena.\n<li class=\"l\"> Dodana je mogu\u0107nost vra\u0107anja na\u010dina izravnog ulazno\/izlaznog rada (O_DIRECT, Direct I\/O) na kori\u0161tenje lakog mehanizma nekes\u030ciraju\u0107eg ulazno\/izlaznog rada (Uncached I\/O) za zahtjeve koji nisu poravnati na granici stranice memorije, koji nisu podr\u017eani u Direct I\/O.\n<li class=\"l\"> Predlo\u017eeni su novi unificirani algoritmi za ograni\u010davanje brzine operacija zapisivanja i pozicioniranja blokova, koji smanjuju fragmentaciju vdev (Virtual Device) okupljanjem vi\u0161e operacija zapisivanja i kori\u0161tenjem za njih ve\u0107ih kontinuiranih slobodnih podru\u010dja umjesto smje\u0161tanja rezultata pojedina\u010dnih operacija zapisivanja u male slobodne prostore.\n<li class=\"l\"> Pove\u0107ana je u\u010dinkovitost enkripcije kori\u0161tenjem AVX2 instrukcija u implementaciji AES-GCM algoritma. U provedenim testovima ubrzanje dose\u017ee 80%.\n<li class=\"l\"> Omogu\u0107eno je postavljanje ZIL blokova (ZFS Intent Log) ne samo na normalne vdev ili na odvojeni ure\u0111aj SLOG, ve\u0107 i na specijalne vdev. Ako je normalni vdev povezan s tvrdim diskom, a specijalni vdev s SSD-om, ova promjena omogu\u0107ava izbjegavanje situacija kada se podaci zapisiju na SSD, a povezani blokovi ZIL na tvrdi disk, \u0161to uzrokuje dodatne ka\u0161njenja.\n<li class=\"l\"> Omogu\u0107eno je postavljanje svojstva special_small_blocks za particije (ZVOL), a ne samo za datote\u010dne sustave, \u0161to omogu\u0107ava organizaciju smje\u0161taja malih blokova na odvojenom specijalnom vdev, na primjer, na SSD-ovima.\n<li class=\"l\"> Dodana je opcija prepisivanja &#171;zfs rewrite -P&#187;, koja po mogu\u0107stvu ostavlja nepromijenjeno logi\u010dko vrijeme kreiranja, \u0161to omogu\u0107ava razlikovanje blokova koji su samo premje\u0161teni u bazen od blokova koji su stvarno izmijenjeni od strane korisnika.\n<li class=\"l\"> Za komande &#171;zpool trim&#187;, &#171;zpool scrub&#187; i &#171;zpool initialize&#187; implementirana je opcija &#171;-a&#187; (&#8212;all), koja omogu\u0107ava izvr\u0161avanje ovih komandi odjednom za sve uvezene bazene.\n<li class=\"l\"> Dodana je komanda &#171;zpool scrub -S -E&#187; za izvo\u0111enje provjere kontrolnih suma podataka unutar zadanih vremenskih intervala.\n<li class=\"l\"> Dodane su nove optimizacije procesa deduplikacije.          <\/ul>\n<p>Izvor: <a content=\"nofollow\" rel=\"nofollow\"
