Publiceret<\/a><\/noindex> udgivelsen af projektet Stratis 2.2<\/a><\/noindex>, udviklet af Red Hat og Fedora-f\u00e6llesskabet for at forene og forenkle konfiguration og administration af et pool af en eller flere lokale lagringsenheder. Stratis tilbyder funktioner som dynamisk allocation af lagerplads, snapshots, integritetsbeskyttelse og oprettelse af lag til caching. Projektkoden er skrevet i Rust og distribueres<\/a><\/noindex> under MPL 2.0 licens.<\/p>\n

Systemet ligner i meget h\u00f8j grad de avancerede administrationsv\u00e6rkt\u00f8jer fra ZFS og Btrfs, men er implementeret som et lag (daemon stratisd<\/a><\/noindex>), der fungerer oven p\u00e5 Linux-kernens device-mapper-subsystem (bruger dm-thin, dm-cache, dm-thinpool, dm-raid og dm-integrity-moduler) og XFS-filsystemet. I mods\u00e6tning til ZFS og Btrfs, arbejder Stratis-komponenter kun i brugerens rum og kr\u00e6ver ikke indl\u00e6sning af specifikke kernelmoduler. Projektet pr\u00e6senteres oprindeligt som ikke kr\u00e6vende<\/a><\/noindex> for administratori kvalifikationer som expert i lagringssystemer. <\/p>\n

Der tilbydes en D-Bus API til administration og cli-v\u00e6rkt\u00f8j<\/a><\/noindex>.
\nStratis' arbejde er blevet testet med blokenheder baseret p\u00e5 LUKS (krypterede partitioner), mdraid, dm-multipath, iSCSI, logiske LVM-volumener samt med forskellige HDD'er, SSD'er og NVMe-lagringsenheder. N\u00e5r der kun er \u00e9n disk i poolen, tillader Stratis brugen af logiske partitioner med snapshots til at rulle \u00e6ndringer tilbage. Ved tilf\u00f8jelse af flere lagringsenheder til poolen bliver det muligt at logisk sammenflette enhederne til et sammenh\u00e6ngende omr\u00e5de. Funktioner som
\nRAID, datakomprimering, deduplicering og oprettelse af fejltolerance underst\u00f8ttes endnu ikke, men er planlagt til fremtiden.<\/p>\n

\"Stratis<\/a><\/noindex><\/center><\/p>\n

I udgivelse 2.2<\/a><\/noindex> er der blevet tilf\u00f8jet nye D-Bus-gr\u00e6nsefladevarianter til at hente egenskaber (FetchProperties), administration (Manager) og interaktion med blokenheder (Blockdev). Muligheden for at informere om opst\u00e5ede h\u00e6ndelser ved tilslutning og frakobling af gr\u00e6nseflader (InterfacesAdded og InterfacesRemoved) er blevet tilf\u00f8jet gennem D-Bus. I stratis-cli-v\u00e6rkt\u00f8jet er forbedret<\/a><\/noindex> input-autocomplete-scenarierne for bash.<\/p>\n
