Kuiswa kweiyo yakaparadzirwa kukanganisa-kushivirira LeoFS chinhu kuchengetedza, inoenderana nevatengi vanoshandisa S3, NFS

Maererano ne Opennet: LeoFS - kugovera kukanganisa-kushivirira chinhu kuchengetedza LeoFS, inowirirana nevatengi vanoshandisa Amazon S3 API uye REST-API, uye zvakare inotsigira NFS server mode. Kune ma optimizations ekuchengetedza zvese zvidiki uye zvakakura zvinhu, kune yakavakirwa-mukati caching mashini, uye kudzokorora kwekuchengetedza pakati pe data data kunogoneka. Zvinangwa zvepurojekiti iyi zvinosanganisira kuwana 99.9999999% kuvimbika kuburikidza nekudzokorodza kudzokororwa kwemakopi uye kubvisa imwe pfungwa yekutadza. Iyo kodhi yeprojekiti yakanyorwa muErlang.

LeoFS ine zvikamu zvitatu:

  • LeoFS Storage -Inoshanda mashandiro ekuwedzera, kudzoreredza uye kudzima zvinhu uye metadata, ine basa rekuita kudzokorora, kudzoreredza uye kumitsetse zvikumbiro zvevatengi.
  • LeoFS Gateway - inoshandisa zvikumbiro zveHTTP uye inodzosera mhinduro kune vatengi vachishandisa REST-API kana S3-API, inova nechokwadi chekuchengetedza data rinonyanya kudiwa mundangariro uye padhisiki.
  • LeoFS Maneja - inotarisa kushanda kweLeoFS Gateway neLeoFS Storage node, inotarisa mamiriro emanodhi uye inotarisa checksums. Inovimbisa kuvimbika kwedata uye kuwanikwa kwekuchengetedza kwakanyanya.

Mune ino post tichaisa Leofs tichishandisa ansible-playbook uye bvunzo S3, NFS.

Kana ukaedza kuisa LeoFS uchishandisa mabhuku ekutamba epamutemo, uchasangana nezvikanganiso zvakasiyana: 1,2. Muchinyorwa chino ndichanyora zvinoda kuitwa kudzivirira kukanganisa uku.

Kwauchamhanya ansible-playbook, unofanirwa kuisa netcat.
