ILizardFS sisistim sefayile esasazwayo que ivumela idatha ukuba isasazwe kwiiseva ezahlukeneyo, kodwa inika ukufikelela kuzo ngohlobo lwesahlulelo esinye esikhulu, esenziwa ngokufanisa izahlulelo zediski yesiko. Icandelo elidityaniswe neLizardFS ixhasa iimpawu zefayile zePOSIX, i-ACL, izitshixo, iziseko, amajelo, iifayile zefowuni, iisimboli kunye neekhonkco ezinzima. Inkqubo ayinalo inqaku elinye lokusilela, onke amacandelo abalulekile.
Le nkqubo yefayile ixhasa ukuthelekiswa kwemisebenzi yedatha (Abathengi abaninzi banokufikelela kwiifayile ngaxeshanye). Kwelinye icala, ukuqinisekisa ukunyamezelana kweziphoso, idatha yahlulwe yaphindaphindwa, esasazwa kwiindawo ezahlukeneyo ezinobunkunkqele (ikopi ezininzi zibekwe kwiindawo ezahlukeneyo), Kwimeko apho ukungasebenzi okanye ukungaphumeleli ukuqhuba, inkqubo iyaqhubeka nokusebenza ngaphandle kokulahleka kolwazi kwaye ngokuzenzekelayo isasaza idatha ithathela ingqalelo iindawo ezishiyekileyo.
Malunga neLizardFS
Le projekthi ILizardFS yasekwa ngo-2013 njengemfoloko yeMooseFS kwaye yahluke ikakhulu kubukho bendlela yokuphindaphindeka esekwe kwiikhowudi zokulungisa i-Reed-Solomon (i-analog ye-raidzN), inkxaso eyandisiweyo ye-ACL, ubukho bomxhasi kwiqonga leWindows, ulungiselelo olongezelelekileyo, inkqubo yoqwalaselo ngakumbi eguqukayo, inkxaso ukufundwa kwedatha okusebenzayo, izikhokelo zesikhombisi kunye nokusebenza kwangaphakathi.
Ukwandisa ukugcinwa, kwanele ukudibanisa iindawo ezintsha kuyo ngaphandle kokuyeka umsebenzi ulondolozo (inkqubo ngokwayo iphinda inxenye yedatha kwiiseva ezintsha kunye nokulinganisa ukugcinwa kunye neeseva ezintsha). Kukwakwenziwa okufanayo ukunciphisa ubungakanani beqela: unokuvala nje izixhobo ezishenxisiweyo.
Idatha kunye nemethadatha igcinwa ngokwahlukeneyo. Ukusebenza kwayo, kuyacetyiswa ukuba kufakelwe iiserver ezimbini ezisebenza kwimowudi yekhoboka eliyintloko, kunye neeseva ezimbini zokugcina idatha (iseva yedatha).
Kwakhona, iiseva zelog zingasetyenziselwa ukubuyisela imethadatha, egcina ulwazi malunga notshintsho lweemethadatha kwaye ekuvumela ukuba ubuyisele umsebenzi wakho ukuba zonke iiseva zemethadatha ezikhoyo zonakele.
Ifayile nganye yahlulwe ngeebhloko (chunk), ukuya kuthi ga kubungakanani obungama-64MB. Iibhloko zihanjisiwe phakathi kweseva zokugcina ngokwendlela ekhethiweyo yokuphindaphindeka: umgangatho (oku kucacisa gca inani leekopi emazibekwe kwiindawo ezahlukeneyo, kubandakanya nokunxibelelana nemikhombandlela eyahlukeneyo, kwidatha ebalulekileyo, ngu Unako ukwandisa inani leekopi , kodwa ezingezizo eziyimfuneko), XOR (RAID5) kunye ne-CE (RAID6).
Ukugcina kunokulinganisela kubungakanani beepetabyte. Kwizicelo, kugcino, ukugcinwa kwemifanekiso ebonakalayo yomatshini, idatha yemultimedia, ukugcinwa kwemali, ukusetyenziswa njengeDRC (iZiko lokuBuyisa iNtlekele) kunye nokusebenza okuphezulu kokugcina ikhomputha xa kukhankanyiwe.
ILizardFS ibonelela ngesantya esiphezulu kakhulu sokufunda iifayile zobuphi na ubungakanani kwaye xa ubhala ibonisa ukusebenza kakuhle xa ubhala iifayile ezinkulu neziphakathi, xa kungekho kuguqulwa rhoqo, umsebenzi onamandla kunye neefayile ezivulekileyo kunye nokusebenza okukodwa okuninzi kweefayile ezincinci.
Phakathi kweempawu kule nkqubo yefayile ubukho benkxaso yogcino bunokubonwa kwakhona Zibonisa imeko yeefayile ngexesha elithile kunye nokumiliselwa okwakhelweyo (iifayile azicinywanga kwangoko kwaye ziyafumaneka ukubuyela ixesha elithile).
Ukufikelela kwisahlulelo kunokulinganiselwa kwidilesi ye-IP okanye iphasiwedi (iyafana neNFS). Iinkqubo zeQoS kunye nolawulo lwezabelo zikhona ukunciphisa umda kunye nobubanzi bebhendi yezinye iindidi zabasebenzisi. Kuyenzeka ukuba kwenziwe iindawo zokugcina iimpahla ezigcinwe ngokwasendaweni, amacandelo azo akumaziko ahlukeneyo edatha.
Uyisebenzisa kanjani iLizardFS ku-Ubuntu?
Kulabo abanomdla wokukwazi ukusebenzisa le fayile banokubonisana ikhonkco elilandelayo, apho ungafumana khona amaxwebhu ayimfuneko. Ikhowudi yeprojekthi ibhalwe ngo-C no-C ++ kwaye ihanjiswa phantsi kwelayisensi ye-GPLv3.
