Ukuhlolwa kwezakhiwo ze-FreeBSD ezidluliselwe ku- “ZFS ku-Linux” sekuqalile

UChris Moore, umdali wephrojekthi ye-PC-BSD kanye nesekela likamongameli we-iXsystems, kumenyezelwe mayelana nokuqala kokuhlola ukufakwa kwemihlangano I-FreeBSD 12-SABLE и I-FreeBSD 13-HEAD, lapho ukuqaliswa kwesistimu yefayela ye-ZFS esekelwe ekuqaleni ku-FreeBSD kuthathelwa indawo ngentuthuko yephrojekthi "I-ZFS ku-Linux". Ngenxa yesinyathelo sokwenza ikhodi ethi "ZFS on Linux" iphatheke kwezinye izinhlelo, iFreeBSD yayikhona ilungisiwe amachweba ama-sysutils/zol (izinsiza) kanye nama-sysutils/zol-kmod (imoduli ye-kernel), manje asikiselwa ukuthi ahlolwe. Kumongo wesistimu yefayela, indlela elula yokuhlola ukuhlinzeka ngezithombe zokufaka ezakhelwe ngaphambilini ezinokuqaliswa komdabu kwe-ZFS kukhutshaziwe kanye nezimbobo ezine-"ZFS ku-Linux" ezifakwe ngaphambili. I-UFS ne-ZFS ingasetshenziswa njengezinhlelo zefayela zokuhlukaniswa kwezimpande.

Masikhumbule ukuthi ngoDisemba wonyaka odlule abathuthukisi beFreeBSD beza nayo isinyathelo ukushintshela ekusetshenzisweni kwe-ZFS kusuka kuphrojekthi "I-ZFS ku-Linux"(ZoL), lapho wonke umsebenzi ohlobene nokuthuthukiswa kwe-ZFS usanda kugxila khona. Isizathu esibaluliwe sokufuduka kwaba ukuminza kwekhodibase ye-ZFS kuphrojekthi ye-Illumos (imfoloko ye-OpenSolaris), eyayisetshenziswa ngaphambili njengesisekelo sokuthuthela izinguquko ezihlobene neZFS kuFreeBSD. Kuze kube muva nje, ukusekelwa kwesisekelo sekhodi ye-ZFS e-Illumos kunikezwe ngabakwaDelphix, abathuthukisa uhlelo lokusebenza. DelphixOS (Imfoloko ye-Illumos). Ngonyaka odlule, i-Delphix yenza isinqumo sokuthuthela ku-"ZFS on Linux", okuholele ekutheni i-ZFS intengantenge kuphrojekthi ye-Illumos futhi ihambise yonke imisebenzi ehlobene nentuthuko kuphrojekthi ye-"ZFS on Linux", manje ethathwa njengokuqaliswa okuyinhloko. I-OpenZFS.

Abathuthukisi be-FreeBSD banqume ukulandela isibonelo esijwayelekile futhi bangazami ukubambelela ku-Illumos, njengoba lokhu kuqaliswa sekuvele kusemuva kakhulu ekusebenzeni futhi kudinga izinsiza ezinkulu ukuze kugcinwe ikhodi futhi kuthuthe izinguquko. "I-ZFS ku-Linux" manje isibonwa njengephrojekthi yokuthuthukisa ye-ZFS eyinhloko, eyodwa, ehlanganyelwayo. Ukusekelwa kwe-FreeBSD kuzohlanganiswa ngokuqondile ku-ZFS kukhodi ye-Linux futhi kuthuthukiswe endaweni yokugcina enkulu yale phrojekthi.

Ezinye izici ezitholakala ethekwini le-FreeBSD "ZFS on Linux" kodwa azikho ekusetshenzisweni kwe-Illumos' ZFS:

• Imodi ye-Multihost (I-MMP;
• I-Multi Modifier Protection);
• Isistimu ye-quota eyandisiwe;
• Ukubethelwa kwamasethi edatha;
• Ukukhetha okuhlukile kwamakilasi okusabalalisa vimba (amakilasi okwabiwa);
• Ukusetshenziswa kwemiyalelo ye-vector processor ukusheshisa ukuqaliswa kwe-RAIDZ nokubalwa kokuhlola;
• Amathuluzi omugqa womyalo athuthukisiwe;
• Kulungiswe izimbungulu eziningi ezihlobene nezimo zomjaho nezingidi.
