Efter ett \u00e5rs utveckling publicerades<\/a><\/noindex> utg\u00e5van av projektet Stratis 2.0<\/a><\/noindex>, som utvecklas av Red Hat och Fedora-gemenskapen f\u00f6r att f\u00f6rena och f\u00f6renkla verktygen f\u00f6r att konfigurera och hantera en pool av en eller flera lokala lagringsenheter. Stratis erbjuder funktioner s\u00e5som dynamisk allokering av lagringsutrymme, snapshots, dataintegritet och skapande av lager f\u00f6r caching. Projektets kod \u00e4r skriven i Rust och sprids<\/a><\/noindex> under MPL 2.0-licensen.<\/p>\n

Systemet p\u00e5minner i h\u00f6g grad om de ut\u00f6kade verktygen f\u00f6r hantering av partitioner i ZFS och Btrfs, men \u00e4r implementerat i form av ett lager (demon stratisd<\/a><\/noindex>), som arbetar ovanp\u00e5 device-mapper-subsystemet i Linux-k\u00e4rnan (anv\u00e4nder modulerna dm-thin, dm-cache, dm-thinpool, dm-raid och dm-integrity) och filsystemet XFS. Till skillnad fr\u00e5n ZFS och Btrfs arbetar komponenterna i Stratis endast i anv\u00e4ndarutrymmet och kr\u00e4ver ingen belastning av specifika k\u00e4rnmoduler. Projektet presenteras ursprungligen som icke kr\u00e4va<\/a><\/noindex> expertkompetens inom lagringssystem f\u00f6r administration. <\/p>\n

F\u00f6r hantering finns ett D-Bus API och cli-verktyg<\/a><\/noindex>.
\nStratis har testats med blockenheter baserade p\u00e5 LUKS (krypterade partitioner), mdraid, dm-multipath, iSCSI, logiska volymer LVM samt med olika HDD, SSD och NVMe-enheter. Med en disk i poolen till\u00e5ter Stratis anv\u00e4ndning av logiska partitioner med snapshots f\u00f6r \u00e5terst\u00e4llning av \u00e4ndringar. N\u00e4r flera enheter l\u00e4ggs till i poolen blir det m\u00f6jligt att logiskt kombinera enheterna till ett sammanh\u00e4ngande omr\u00e5de. Funktioner som
\nRAID, datakomprimering, deduplicering och uppbyggnad av redundans st\u00f6ds f\u00f6r n\u00e4rvarande inte, men \u00e4r planerade f\u00f6r framtiden.<\/p>\n

\"Utg\u00e5van<\/a><\/noindex><\/center><\/p>\n

I ny<\/a><\/noindex> utg\u00e5va<\/a><\/noindex> kr\u00e4ver en uppdaterad version av kompilatorn Rust (minst 1.37, men rekommenderad 1.38). Den betydande version\u00e4ndringen beror p\u00e5 omnamnandet av vissa D-Bus-gr\u00e4nssnitt och omarbetningen av hur man arbetar med D-Bus (ett antal grundl\u00e4ggande egenskaper har avgr\u00e4nsats, medan andra nu beg\u00e4rs genom en ny metod, FetchProperties).<\/p>\n
