Abathuthukisi beFreeBSD bahlose ukuhambisa i-ZFS baye ku-ZoL "ZFS ku-Linux"

Ezinsukwini ezimbalwa ezedlule i onjiniyela abaphethe iphrojekthi yeFreeBSD bathumele uhlelo lokuhumusha lohlelo lwefayela le-ZFS esetshenziswe kuphrojekthi yokuqalisa yephrojekthi ye- "ZFS on Linux" (ZoL), ethuthukisa ichweba le-ZFS le-Linux.

Isizathu sokufuduka ukumiswa kwekhodi ye-ZFS kusuka kuphrojekthi ye-Illumos (imfoloko ye-OpenSolaris), ebikade isetshenziswa njengesisekelo sokudlulisa izinguquko ezihlobene ne-ZFS ku-FreeBSD.

Mayelana I-ZFS

I-ZFS uhlelo lwefayela nomphathi wevolumu owakhiwe ekuqaleni yiSun Microsystems nge-Solaris OS yakho. Incazelo yoqobo ibithi 'Zettabyte File System', kepha manje sekuyisiqubulo esiphindaphindwayo.

I-ZFS ivelela amandla ayo amakhulu, ukuhlanganiswa kohlelo lwefayela olwehlukanisiwe ngaphambili kanye nemiqondo yemenenja yevolumu kumkhiqizo owodwa, uhlaka olusha kudiski, amasistimu wefayela engasindi, nokuphathwa kwesikhala sokugcina okulula.

Kuze kube muva nje, Iningi lentuthuko ehlobene ne-ZFS yenziwa iphrojekthi ye- "ZFS on Linux" kanye nenkampani yeDelphix.

Inkampani ithuthukisa uhlelo lokusebenza lwe-Delphix DelphixOS (imfoloko ye-Illumos) eyayinikeze ukwesekwa kwe-ZFS ku-Illumos codebase.

Ukuthuthukiswa kwe- I-ZFS izothuthela eLinux

Ezinyangeni ezimbalwa ezedlule (ekuqaleni konyaka), UDelphix umemezele ushintsho ekusetshenzisweni kwe- "ZFS kuLinux", Ekugcineni okuletha yonke imisebenzi ehlobene ne-ZFS endaweni eyodwa.

Kumaphrojekthi we-ZFS aqhubekayo futhi aqashwe, kusele i- "ZFS on Linux" kuphela, manje engathathwa njengokuqaliswa kokuqala kwe-OpenZFS.

Njengoba ukuqaliswa kwe-ZFS ngabakwa-Illumos sekuvele kusilele emuva ngemuva kwe- "ZFS on Linux" ngokusebenza.

Abathuthukisi beFreeBSD babonile ukuthi umphakathi weFreeBSD awunamandla anele okulungisa nokuthuthukisa isisekelo sekhodi esikhona wedwa.

Uma uqhubeka nokusebenzisa i-Illumos, igebe lokusebenza lizokwanda kuphela futhi ukudluliswa kwama-patch kuzodinga izinsiza eziningi ngokwengeziwe.

Esikhundleni sokuzama ukunamathela ku-Illumos, ithimba labasekeli be-ZFS eFreeBSD linqume ukwamukela i- "ZFS on Linux" njengephrojekthi enkulu yokuthuthukisa iZFS, iqondise izinsiza ezikhona ukukhulisa ukutholakala kwekhodi yazo, futhi zisebenzise i-base base yazo. ukuqaliswa kwe-ZFS kweFreeBSD.

Ukwesekwa kweFreeBSD kuzohlanganiswa ngqo kukhodi ye- "ZFS on Linux" futhi kuzothuthukiswa ikakhulukazi ezinqolobaneni zale phrojekthi (udaba lokuthuthukiswa ngokuhlanganyela endaweni eyodwa seluvele luvunyelwene noBrian Behlendorf, umholi wephrojekthi weZFS kuLinux).

Kungani iLinux futhi ungaqhubeki kuFreeBSD?

Okwamanje, isibonelo sesikhumulo se- "ZFS on Linux" seFreeBSD sesivele silungiselelwe ukubuyekezwa.

Ukuyihlanganisa nekhodebase yeFreeBSD, ihlala ingeza izici eziningana ezintsha kuhlaka lwe-opencrypto.

Ukuhlanganisa itheku nesisekelo esiyinhloko sekhodi "ZFS ku-Linux", kufanele bangeze ukwesekwa kweFreeBSD ohlelweni lokuhlanganisa oluqhubekayo, baqinisekise ukuthi ikhodi idlulisa konke ukuhlolwa, futhi yenza izivivinyo zekhwalithi ezingeziwe.

Ukushintshwa kokuqaliswa kwe-ZFS ku-FreeBSD codebase kuhlelelwe umhlaka-15 Ephreli, uma sekuphele izinyanga ezimbili itheku lazinza (ngaphandle kwalokho umnqamulajuqu uzoshintshwa).

Ngokuzayo, izinyanga ezintathu, izinguqulo ezindala nezintsha zeZFS zizohlangana, ngemuva kwalokho kuzokhishwa ikhodi endala ye-Illumos esekwe ku-ZFS.

Ngokusebenza okusha okutholakala echwebeni le-ZoL le-FreeBSD, kepha hhayi ekusetshenzisweni kwe-Illumos ZFS, qaphela imodi ye-multihost (i-MMP, ukuvikelwa kwezinto eziningi), uhlelo lwe-quota oluthuthukile, ukubethela kwedathasethi, ukukhetha okuhlukile kwamakilasi we-block block. izifundo).

Ukusetshenziswa kwemiyalo ye-vector processor ukusheshisa ukuqaliswa kwe-RAIDZ nokubala amasheke, amathuluzi alayini athuthukisiwe.

I-ZoL ibuye ilungise izimbungulu eziningi ezihlobene nezimo zomjaho kanye nama-hang, angakalungiswa kukhodi ye-Illumos.
