An canza codebase na FreeBSD don amfani da OpenZFS (ZFS akan Linux)

Aiwatar da tsarin fayil na ZFS a cikin taken FreeBSD (HEAD) fassara don amfani da lambar OpenZFS haɓaka tushen lambar "ZFS akan Linux» a matsayin bambance-bambancen tunani na ZFS. A cikin bazara, tallafin FreeBSD ya koma babban aikin OpenZFS, bayan haka ci gaban duk canje-canje masu alaƙa da FreeBSD ya ci gaba a can, kuma masu haɓaka FreeBSD sun sami damar canja wurin da sauri cikin tsarin duk sabbin abubuwan da aikin OpenZFS ya haɓaka.

Daga cikin fasalulluka waɗanda suka zama samuwa a cikin FreeBSD bayan canzawa zuwa OpenZFS: tsarin faɗaɗa ƙididdiga, ɓoyayyun bayanan bayanai, zaɓi daban-daban na azuzuwan rarraba toshe (azuzuwan rarrabawa), yin amfani da umarnin processor na vector don hanzarta aiwatar da RAIDZ da checksum. lissafi, goyan baya ga ZSTD matsawa algorithm, yanayin multihost (MMP, Multi Modifier Kariya), ingantaccen kayan aikin layin umarni, gyare-gyare don yawancin yanayin tsere da batutuwan kullewa.

Bari mu tuna cewa a cikin Disamba 2018, masu haɓaka FreeBSD sun fito da himma canzawa zuwa aiwatar da ZFS daga aikin "ZFS akan Linux"(ZoL), wanda duk ayyukan da suka shafi ci gaban ZFS ya mayar da hankali kan kwanan nan. Dalilin da aka ambata don ƙaura shine tabarbarewar lambar lambar ZFS daga aikin Illumos (cokali mai yatsa na OpenSolaris), wanda a baya aka yi amfani da shi azaman tushen ƙaura da canje-canje masu alaƙa da ZFS zuwa FreeBSD.

Har zuwa kwanan nan, babban taimako don tallafawa tushen lambar ZFS a Illumos ya kasance ta Delphix, wanda ke haɓaka tsarin aiki. DelphixOS (Illumos cokali mai yatsa). Shekaru uku da suka wuce, Delphix ya yanke shawarar matsawa zuwa "ZFS akan Linux", wanda ya haifar da ZFS ta tsaya daga aikin Illumos da kuma mayar da hankali ga duk ayyukan ci gaba a cikin aikin "ZFS akan Linux", wanda yanzu ana ɗaukarsa babban aiwatarwa. OpenZFS.

Masu haɓaka FreeBSD sun yanke shawarar bin misali na gabaɗaya kuma ba su yi ƙoƙarin riƙe Illumos ba, tunda wannan aiwatarwa ya riga ya yi nisa a cikin aiki kuma yana buƙatar manyan albarkatu don kiyaye lambar da ƙaura canje-canje. OpenZFS dangane da "ZFS akan Linux" yanzu ana ɗaukar aikin ci gaban ZFS guda ɗaya na haɗin gwiwa.
