Ukuqoqwa kwezinhlelo zamafayela ezisatshalalisiwe
Amandla okugcina idatha kanye idatha ye-meta
Ukuqina ukwehluleka kwama-node okukodwa
Ukuvumelana nezimo ukunweba noma ukuncipha kwenethiwekhi nganoma yisiphi isikhathi
Ukwazi ukugijima kakhulu inkumbulo ephansi amaseva
A kusatshalaliswa uhlelo lwefayela , ngokuvamile, nikeza ifayela le- kahle POSIX isikhombimsebenzisi sokuhambisana kwesistimu yefayela. Le yingxenye yencazelo yayo kakhulu ngoba ukwakha iqoqo lama-node eligcina idatha ngendlela esatshalalisiwe kungatholakala ngezindlela eziningi ezahlukahlukene, kepha ukwakha eyodwa enikeza ukufinyelela kuyasebenziseka isikhombimsebenzisi sohlelo lwefayela siyinselele. Isistimu yefayela ngokuvamile kucatshangwa ukuthi iyiyo yendawofuthi ngenxa yalokho, izinhlelo eziningi zisebenzisa ukufinyelela okusheshayo kuso, zinganaki izingqinamba zokubambezeleka ezingase zivele ohlelweni lwefayela olusekelwa yidatha ekude. Izicelo ezimbalwa kakhulu ezibona phakathi kwezinhlelo zasendaweni nezikude.
Ukuswayipha amafayili-wezinhlelo ngokusatshalaliswa kungathathwa njengefomu le- ukusebenzisana emuva ... esimweni lapho ufuna ukufaka uhlelo lokusebenza endaweni yamafu ethembele ekufinyeleleni kohlelo lwefayela kusendlalelo salo sedatha, ifu kufanele linikeze isikhombimsebenzisi sohlelo lwefayela esingaziphindaphinda emishinini. Noma kunjalo, esimweni esisodwa somsebenzisi, kungabhekwa futhi njengendlela yokunciphisa ukuphatha ngaphezulu ... esikhundleni sokulandela izipele zedatha kusuka kuseva ngayinye oyisebenzisayo, ungalandelela impilo yohlelo lwefayela olususelwa kunethiwekhi bese uhlela izipele phezu kwakho.
Uma ungadingi ukufinyelela okuqinile kuma-semantics wezinhlelo zamafayela, isikhombimsebenzisi sokusabalalisa into esisatshalaliswa silula futhi njenge ephathekayo futhi indawo yonke njengohlelo lwefayela, olunomthwalo omncane wokuvumelanisa kunethiwekhi kusukela ekugcineni kwento ngayinye, ayibambi idatha ye-meta. Enye isoftware yokubeka into inikeza isikhombimsebenzisi sohlelo lwefayela esakhelwe phezulu.
Njengoba inhloso yethu hhayi idatha enkulu, asizinaki izixazululo ezifana HDFS.
I-OpenAFS : lolu akusilo uhlelo lwefayela olusatshalaliswa kahle, ngoba luyilo kuhlanganisiwe okusho ukuthi ukwehluleka kwe-node eyodwa kungadala ukuphazamiseka.
MinFS : I-MinFS umshayeli we-fuse weMinio, okuyisitoreji sento ehanjiswe phambili enekhodi yokusula, kepha akubonakali kushibhile kuzinsizakusebenza.
xtreemefs : I-XtreemeFS ifinyelela ukuqina ngokulingana ne-RAID0 ngenethiwekhi
gllusfs: kulula ukusetha kepha ukusebenza okungalungile
ceph : kunzima ukusetha (nokuphatha) kepha ngokusebenza okuhle kakhulu (nokulungiswa)
izibankwa : ukusebenza okuhloniphekile, inkumbulo yokuqala ephansi yememori kepha ephezulu ngaphansi komthwalo osindayo
amawolintshi : unyawo oluncane, imodyuli ye-kernel ne-fuser module, elinde ku-v3 yemethadatha ye-async
izinyosi : i-footprint ephansi, i-kernel module (kepha i-fuser module engaxhunywanga), ukusebenza okuhle kakhulu
izimila zasolwandle : isitoreji sezinto esingaxhuma kalula nge-fuser module
Lapha umphumela wokuma kwetafula elithile, awumbozi wonke amasistimu wefayela, futhi kungenzeka uphelelwe yisikhathi kuleli phuzu, nakuf2fs ukulondolozwa kwemiphumela kungenzeka kudlule :)

Nayi idatha yamabhentshi
Amashobhu we-sysctl abhekelwe ukwenziwa okuphezulu, kepha kufanele kungabi nalusizo, futhi mhlawumbe ahlanze amabhentshi, ngoba kunethiwekhi enkulu kakhulu lawo mashobana awahlali esetshenziswa, futhi kuncike kwinethiwekhi , ngakho-ke noma ngabe zisetshenzisiwe, kungaba khona ezinye izingqinamba ezikhona.
Ukuqhathanisa okwengeziwe, kusuka ku-wikipedia, kusuka ezilwaneni zasolwandle.
