Kent Overstreet har publicerat en utg\u00e5va av filsystemet Bcachefs 1.33.0. Utg\u00e5van omfattar tv\u00e5 paket: bcachefs-kernel-dkms med en k\u00e4rnmodul som byggs med hj\u00e4lp av DKMS-systemet (Dynamic Kernel Module Support) och bcachefs-tools med det anv\u00e4ndarrumsk\u00f6rande verktyget bcachefs, som implementerar kommandon f\u00f6r att skapa (mkfs), montera, \u00e5terst\u00e4lla och kontrollera filsystemet. Paketen \u00e4r byggda f\u00f6r Debian, Ubuntu, Fedora, openSUSE, NixOS och Arch Linux. DKMS-modulen st\u00f6der k\u00e4rnor i Linux fr\u00e5n och med version 6.16. <\/p>\n
Den nya versionen har lagt till funktionen \u201ereconcile\u201c (rebalance_v2), som markerats som den st\u00f6rsta f\u00f6r\u00e4ndringen i filsystemet p\u00e5 de senaste tv\u00e5 \u00e5ren. Till skillnad fr\u00e5n den tidigare tillg\u00e4ngliga \u201erebalance\u201c-l\u00e4get, m\u00f6jligg\u00f6r mekanismen \u201ereconcile\u201c ombalansering av inte bara data (till exempel replikering av flera kopior p\u00e5 olika lagringsenheter), utan \u00e4ven metadata i filsystemet (till exempel f\u00f6r att flytta metadata efter att en extra lagringsenhet lagts till i poolen). Dessutom kan reconcile nu till\u00e4mpas p\u00e5 alla in-\/utmatningsalternativ, inte bara f\u00f6r bakgrundskopierings- och kompressions\u00e5tg\u00e4rder. I reconcile beaktas \u00e4ven automatiskt \u00e4ndringar av enhetsalternativ eller inst\u00e4llningar och degraderad data och metadata replikeras omedelbart. <\/p>\n
I reconcile anv\u00e4nds separata index f\u00f6r: h\u00f6gprioriterade operationer; optimering av databehandling p\u00e5 h\u00e5rddiskar; data som planeras f\u00f6r behandling som f\u00f6r n\u00e4rvarande inte kan utf\u00f6ras (till exempel p\u00e5 grund av platsbrist). St\u00f6d har lagts till f\u00f6r att skapa ett filsystem p\u00e5 en enda enhet i dubbel replikationsl\u00e4ge (replicas=2) \u2013 i en s\u00e5dan konfiguration kommer tillskottet av en andra enhet att leda till automatisk replikering av data till den nya disken, utan att anv\u00e4ndaren beh\u00f6ver vidta n\u00e5gra \u00e5tg\u00e4rder. <\/p>\n
Bland andra \u00e4ndringar: <\/p>\n
Bcachefs-projektet utvecklar ett filsystem som syftar till att kombinera den ut\u00f6kade funktionaliteten av Btrfs och ZFS med den prestanda, tillf\u00f6rlitlighet och skalbarhet som k\u00e4nnetecknar XFS. Bcachefs st\u00f6der funktioner som att inkludera flera enheter i en partition, flerlagers lagring (med ett nedersta lager av ofta anv\u00e4nda data baserat p\u00e5 snabba SSD:er och ett \u00f6vre lager med mindre efterfr\u00e5gade data fr\u00e5n h\u00e5rddiskar), replikering (RAID 1\/10), caching, transparent datakomprimering (med LZ4, gzip och ZSTD-l\u00e4gen), tillst\u00e5ndsklipp (snapshots), integritetsverifiering via kontrollsummor, lagring av Reed-Solomons felkorrektionskoder (RAID 5\/6) och lagring av information i krypterad form (med ChaCha20 och Poly1305). N\u00e4r det g\u00e4ller prestanda \u00f6vertr\u00e4ffar Bcachefs Btrfs och andra filsystem baserade p\u00e5 Copy-on-Write-mekanismen och visar en hastighet som \u00e4r n\u00e4ra Ext4 och XFS.
