Ngokusho : - isitoreji sento esabalalisiwe esibekezelela amaphutha , ehambisana namakhasimende asebenzisa i-Amazon S3 API ne-REST-API, futhi isekela imodi yeseva ye-NFS. Kukhona ukulungiselelwa kokugcina kokubili izinto ezincane nezinkulu kakhulu, kukhona indlela eyakhelwe ngaphakathi yokugcina isikhashana, futhi ukuphindaphinda kwesitoreji phakathi kwezikhungo zedatha kungenzeka. Imigomo yale phrojekthi ihlanganisa ukuzuza ukwethembeka okungu-99.9999999% ngokuphindaphinda okungafuneki kwezimpinda kanye nokuqeda iphuzu elilodwa lokwehluleka. Ikhodi yephrojekthi ibhalwe ngesi-Erlang.
I-LeoFS iqukethe izingxenye ezintathu:
- - Isebenzela imisebenzi yokwengeza, ukubuyisa kanye nokususa izinto kanye nemethadatha, inesibopho sokuphindaphinda, ukubuyisela kanye nokufaka izicelo zamaklayenti kulayini.
- - isebenzela izicelo ze-HTTP futhi iqondise kabusha izimpendulo kumakhasimende asebenzisa i-REST-API noma i-S3-API, iqinisekisa ukulondolozwa kwedatha edingeka kakhulu kumemori nakudiski.
- β iqapha ukusebenza kwe-LeoFS Gateway ne-LeoFS Storage node, iqapha isimo samanodi futhi ihlole amanani okuhlola. Iqinisekisa ubuqotho bedatha nokutholakala kwesitoreji esiphezulu.
Kulokhu okuthunyelwe sizofaka i-Leofs sisebenzisa i-ansible-playbook kanye nokuhlola i-S3, i-NFS.
Uma uzama ukufaka i-LeoFS usebenzisa izincwadi zokudlala ezisemthethweni, uzohlangabezana namaphutha ahlukahlukene: ,. Kule post ngizobhala okumele kwenziwe ukugwema la maphutha.
Lapho uzosebenzisa i-ansible-playbook, udinga ukufaka i-netcat.
