I kodebasen «ZFS on Linux<\/a><\/noindex>«, der udvikles under projektets vinger OpenZFS<\/a><\/noindex> som en referenceimplementering af ZFS, er blevet vedtaget<\/a><\/noindex> \u00e6ndringer, der tilf\u00f8jer support<\/a><\/noindex> af operativsystemet FreeBSD. Koden, der er tilf\u00f8jet til «ZFS on Linux», er testet i FreeBSD version 11 og 12. P\u00e5 denne m\u00e5de beh\u00f8ver udviklerne af FreeBSD ikke l\u00e6ngere at underst\u00f8tte deres eget synkroniserede afgrening «ZFS on Linux», og udviklingen af alle relaterede \u00e6ndringer til FreeBSD vil foreg\u00e5 i hovedprojektet. Desuden vil funktionaliteten i FreeBSD's hovedgren af «ZFS on Linux» blive testet i et kontinuerligt integrationssystem under udviklingen. <\/p>\n

Vi minder om, at i december 2018 fremlagde FreeBSD-udviklerne initiativen<\/a><\/noindex> overgangen til ZFS-implementeringen fra projektet «ZFS on Linux<\/a><\/noindex>» (ZoL), omkring hvilken al aktivitet relateret til udviklingen af ZFS har v\u00e6ret koncentreret p\u00e5 det seneste. Som \u00e5rsag til migreringen blev stagnationen i kodebasen ZFS fra Illumos-projektet (et fork af OpenSolaris) n\u00e6vnt, som tidligere blev brugt som grundlag for overf\u00f8rslen af relaterede \u00e6ndringer til ZFS i FreeBSD. Det prim\u00e6re bidrag til underst\u00f8ttelsen af ZFS kodebasen i Illumos blev indtil for nylig givet af Delphix, der udvikler operativsystemet DelphixOS<\/a><\/noindex> (fork af Illumos). For to \u00e5r siden besluttede Delphix at skifte til «ZFS on Linux», hvilket f\u00f8rte til stagnationen af ZFS fra Illumos-projektet og koncentrationen af al relateret udviklingsaktivitet i «ZFS on Linux» projektet, som nu betragtes som den prim\u00e6re implementering OpenZFS<\/a><\/noindex>.<\/p>\n

Udviklerne af FreeBSD har besluttet at f\u00f8lge det generelle eksempel og ikke fors\u00f8ge at holde fast i Illumos, da denne implementering allerede er st\u00e6rkt bagud med hensyn til funktionalitet og kr\u00e6ver store ressourcer til kodevedligeholdelse og overf\u00f8rsel af \u00e6ndringer. «ZFS on Linux» betragtes nu som det prim\u00e6re, f\u00e6lles projekt til udvikling af ZFS. Blandt mulighederne, der er tilg\u00e6ngelige i «ZFS on Linux» for FreeBSD, men som mangler i ZFS-implementeringen fra Illumos: multihost-tilstand (MMP<\/a><\/noindex>, Multi Modifier Protection), avanceret kvotesystem, kryptering af datas\u00e6t, separat valg af allocationsklasser, brug af vektorprocessor-instruktioner til at accelerere implementeringen af RAIDZ og beregning af kontrolsummer, forbedrede kommandolinjev\u00e6rkt\u00f8jer, samt rettelse af mange fejl relateret til race conditions og deadlocks.<\/p>\n
