Udgivelsen af Stratis 3.0-projektet, udviklet af Red Hat og Fedora-f\u00e6llesskabet, har til form\u00e5l at ensrette og forenkle v\u00e6rkt\u00f8jerne til konfiguration og administration af en pulje af lokale lagermedier. Stratis tilbyder funktioner som dynamisk tildeling af lagerplads, snapshots, integritetssikring og lagdeling til caching. Stratis underst\u00f8ttelse er integreret i Fedora- og RHEL-distributioner siden Fedora 28 og RHEL 8.2. Projektkoden distribueres under MPL 2.0-licensen. <\/p>\n

Systemet minder i h\u00f8j grad om de avancerede partitioneringsv\u00e6rkt\u00f8jer i ZFS og Btrfs, men er implementeret som et lag (demon stratisd), der k\u00f8rer ovenfor device-mapper subsystemet i Linux-kernen (anvender modulerne dm-thin, dm-cache, dm-thinpool, dm-raid og dm-integrity) og XFS-filsystemet. I mods\u00e6tning til ZFS og Btrfs arbejder Stratis' komponenter udelukkende i brugerens rum og kr\u00e6ver ikke indl\u00e6sning af specifikke kerne-moduler. Projektet pr\u00e6senteres oprindeligt som ikke kr\u00e6vende for administration af eksperter inden for lagringssystemer. <\/p>\n

Der tilbydes et D-Bus API og en cli-utility til administration. Stratis' funktionalitet er blevet testet med block-enheder baseret p\u00e5 LUKS (krypterede partitioner), mdraid, dm-multipath, iSCSI, logiske LVM-volumener samt med forskellige HDD'er, SSD'er og NVMe-lagringsenheder. Hvis der kun er \u00e9n disk i puljen, giver Stratis mulighed for at bruge logiske partitioner med snapshot-support til at tilbagef\u00f8re \u00e6ndringer. N\u00e5r flere lagringsenheder tilf\u00f8jes til puljen, opst\u00e5r der mulighed for logisk at sammenk\u00e6de enhederne i et sammenh\u00e6ngende omr\u00e5de. Funktioner som RAID, datakomprimering, deduplikation og oprettelse af fejltilgivelse underst\u00f8ttes endnu ikke, men er planlagt til fremtiden. <\/p>\n

\"Udgivelse<\/center> <\/p>\n

Den betydelige versions\u00e6ndring kan forklares ved \u00e6ndringen af interface til styring via D-Bus og oph\u00f8r af underst\u00f8ttelse af FetchProperties-interface til fordel for brugen af D-Bus-baserede egenskaber og metoder. Den nye udgave inkluderer ogs\u00e5 en kontrol af udev-regler ved hj\u00e6lp af libblkid f\u00f8r \u00e6ndringer foretages, en overarbejdning af eventbehandling fra DeviceMapper, \u00e6ndret intern repr\u00e6sentation af fejlh\u00e5ndteringssystemer, revideret kode til rollback af \u00e6ndringer, samt muligheden for at angive logisk st\u00f8rrelse ved oprettelse af filsystemer. I Clevis-rammen, der anvendes til automatisk kryptering og dekryptering af data p\u00e5 partitions, er SHA-256 hashes blevet implementeret i stedet for SHA-1. Muligheden for at \u00e6ndre adgangss\u00e6tningen og regenerere bindinger til Clevis er ogs\u00e5 tilf\u00f8jet.
