Ilogo ye-OpenZFS
Zisanda kumenyezelwa ukukhishwa kwezinguqulo zokulungisa ze-OpenZFS 2.1.14 kanye ne-2.2.2, lapho ithimba lokuthuthukisa i-OpenZFS ukuxazulula inkinga kukhodi yokuhlola ukuhambisana kwenqolobane okubangela ukonakala kwedatha kumafayela eziqukethe izindawo ezingenalutho lapho zikopishwa ngemva kokwenza izinguquko.
Futhi ukwethulwa okukodwa kwakunganele, kodwa Ukwethulwa okusha okubili bekufanele kwenziwe ukuze ngaleyo ndlela kuxazulule inkinga efanayo. Ngokwengxenye yayo, i-OpenZFS 2.2.2 yayihloselwe kokubili i-FreeBSD 14, kanye nokusatshalaliswa kweLinux okuningana, okuhlanganisa Ubuntu 23.10, kuyilapho inguqulo ye-OpenZFS isebenza ku-FreeBSD kusukela kunguqulo 12.
Kuyafaneleka ukusho lokho Ukukhishwa kwe-OpenZFS 2.2.0 kulethe udaba lwesiphazamisi senkohlakalo ngesici esisha se-block cloning esithatha indawo yedatha ngoziro ngaphandle kwesixwayiso, ngaphandle kokutholwa, ngaphandle kwenkomba yokuthi kukhona okungalungile uze uzame ukufunda idatha.
Ekuqaleni wayecabanga ukuthi i-OpenZFS 2.2.0 yilapho inkinga yayifakwe khona, kodwa kwakungenjalo., njengoba kushiwo, lokhu kukhululwa adalule iphutha eliyisisekelo ebelikhona iminyaka futhi imane yenza inkinga ekhona ibe lula kakhulu.
Ekuqaleni, bazame ukulungisa inkinga ngenguqulo 2.2.1, kodwa ukulungisa akuzange kusebenze. Isiphazamisi asizange sinakwe isikhathi eside futhi saqala ukuvela ngemva kokwenziwa kwezinguquko kuhlelo lwe-"cp" kuphakheji ye-coreutils 9.x. Inkinga akufanele ivele ku-Red Hat Enterprise Linux kanye nokusabalalisa okusekelwe kuyo, njengoba i-RHEL 9 isebenzisa iphakheji ye-coreutils 8.x enomqondo ohlukile wokusetshenziswa kwe-“cp”.
Inkinga ivela uma usebenzisa izinsiza zokukopisha ifayela engakhomba futhi ilungiselele izindawo ezingenalutho kumafayela. Inkohlakalo ingase yenzeke ezinhlelweni zamafayela alayishiwe lapho kukopishwa ifayela, uma ukusebenza kwenziwa cishe ngokushesha ngemva koshintsho futhi enye idatha isala kuphela kunqolobane engcolile futhi ayikasuswa kudiski.
Ukwandisa ukuphathwa kwezindawo ezingenalutho kumafayela, i-OpenZFS, kusukela kunguqulo 0.6.2, isekela imisebenzi ye-SEEK_HOLE kanye ne-SEEK_DATA, okuvumela indawo engenalutho yefayela ukuthi yeqiwe lapho lifundwa kudiski. Izindawo ezingenalutho ziyabonakala futhi ulwazi olumayelana nazo lulondolozwa kuphela ngemva kokuba yonke idatha esele ehlotshaniswa nefayela eligcinwe kunqolobane igxiliswe kudiski. Ukuze kuqalwe ukushintshwa, i-OpenZFS inesheke elihlola ubukhona bedatha engagciniwe futhi iphoqelela ukuguquguquka kudiski edingekayo ukuze usebenzise i-SEEK_HOLE kanye ne-SEEK_DATA.
Ngeshwa, ukuqinisekiswa bekungaphelele futhi, Kwezinye izimo, idatha emayelana nesimo sokuqalisa kabusha yayinqunywa ngokungalungile futhi ulwazi oludala mayelana nokuqukethwe kwefayela lwalukudiski uma isicelo senzeke esikhathini esincane phakathi kokusebenza kwe-cache flush.
Ukufunda imisebenzi ethuthukisa ukulayishwa kwezindawo ezingenalutho okwamanje kungase kweqe ukufunda ingxenye yedatha, icabange ukuthi ayinalutho, kuyilapho uhlelo olusebenza ngefayela ngaphambili belungenza izinguquko ezindaweni ezingenalutho. Ngenxa yalokho, ukusetshenziswa komkhiqizo "cp" ingase ikhiqize ikhophi equkethe izindawo ezingenalutho lapho zingekho khona efayeleni lokuqala.
Ngesikhathi sophenyo olwenziwayo, kwavezwa ukuthi isiphazamisi siphinde saqinisekiswa e-Illumos, imfoloko yomthombo ovulekile ye-OpenSolaris eqhubekile nentuthuko kusukela u-Oracle abulala iphrojekthi yomthombo ovulekile ngo-2010.
Ngaphezu kokulungiswa Ukonakala kwedatha, ukukhishwa kwenguqulo Kubandakanya nokunye ukulungiswa kweziphazamisi nokuthuthukiswa, phakathi kwazo ikhambi le-ZFS eligqamayo ukuze izifinyezo (zfs/snapshot) zibonakale ku-NFS ku-FreeBSD, izinkinga zokuhambisana ne-Linux 6.6 ziyabhekwa, futhi amaphutha okuhlanganiswa namagobolondo okuqalisa ku-FreeBSD ayalungiswa.
Okokugcina uma unentshisekelo yokwazi kabanzi ngakho, ungabheka imininingwane ku- isixhumanisi esilandelayo.
