Kent Overstreet har offentliggjort version 1.33.0 af filsystemet Bcachefs. Udgaven d\u00e6kker to pakker: bcachefs-kernel-dkms med en kernelmodul, der kompileres ved hj\u00e6lp af DKMS (Dynamic Kernel Module Support), og bcachefs-tools med et brugerrum v\u00e6rkt\u00f8j bcachefs, der implementerer kommandoer til oprettelse (mkfs), montering, restauration og kontrol af filsystemet. Pakkerne er bygget til Debian, Ubuntu, Fedora, openSUSE, NixOS og Arch Linux. DKMS-modulet underst\u00f8tter arbejde med Linux-kerneler fra version 6.16. <\/p>\n
I den nye version er der tilf\u00f8jet funktionalitet til 'reconcile' (rebalance_v2), som er blevet markeret som den st\u00f8rste \u00e6ndring i FS i de sidste to \u00e5r. I mods\u00e6tning til den tidligere tilg\u00e6ngelige 'rebalance'-tilstand, g\u00f8r 'reconcile' det muligt at udf\u00f8re rebalance ikke kun af data (for eksempel replikering af flere kopier til forskellige lagringsenheder), men ogs\u00e5 metadata i FS (for eksempel til overf\u00f8rsel af metadata efter tilf\u00f8jelse af en ekstra enhed til puljen). Derudover er 'reconcile' nu anvendelig for alle ind- og udgangsmuligheder, og ikke kun for baggrundskopierings- og komprimeringsoperationer. 'Reconcile' tager ogs\u00e5 automatisk h\u00f8jde for \u00e6ndringer i indstillingerne eller konfigurationerne af enheder og replikere straks nedgraderede data og metadata. <\/p>\n
I 'reconcile' anvendes s\u00e6rskilte indekser til: h\u00f8jt prioriterede operationer; optimering af databehandling p\u00e5 disklagringsenheder; data, der er planlagt til behandling, som ikke kan udf\u00f8res endnu (for eksempel p\u00e5 grund af pladsmangel). Der er tilf\u00f8jet st\u00f8tte til oprettelse af filsystemer p\u00e5 en enkelt enhed i dobbelt replikationstilstand (replicas=2) \u2014 i en s\u00e5dan konfiguration vil tilf\u00f8jelsen af en anden enhed automatisk f\u00f8re til replikering af data til den tilf\u00f8jede disk, uden behov for, at brugeren foretager nogen handlinger. <\/p>\n
Blandt andre \u00e6ndringer: <\/p>\n
Bcachefs er et projekt, der udvikler et filsystem med fokus p\u00e5 at kombinere den avancerede funktionalitet, der er karakteristisk for Btrfs og ZFS, med det niveau af ydeevne, p\u00e5lidelighed og skalerbarhed, som er typisk for XFS. Bcachefs underst\u00f8tter funktioner som muligheden for at inkludere flere enheder i et volumen, lagdeling af lagringsmedier (et hurtigt SSD-lag til ofte brugte data og et langsommere harddisk-lag til sj\u00e6ldnere brugte data), replikering (RAID 1\/10), caching, gennemsigtig datakomprimering (LZ4, gzip og ZSTD), snapshots, integritetsverifikation ved hj\u00e6lp af kontrolsummer, mulighed for at lagre Reed-Solomon-koder (RAID 5\/6), og lagring af oplysninger i krypteret form (ChaCha20 og Poly1305 benyttes). Bcachefs overg\u00e5r Btrfs og andre filsystemer baseret p\u00e5 Copy-on-Write-mekanismen i ydeevne og viser hastigheder t\u00e6t p\u00e5 Ext4 og XFS. \u041a\u0435\u043d\u0442
