Kent Overstreet a publicat lansarea sistemului de fi\u0219iere Bcachefs 1.33.0. Lansarea acoper\u0103 dou\u0103 pachete: bcachefs-kernel-dkms, cu un modul de kernel compilat cu ajutorul sistemului DKMS (Dynamic Kernel Module Support), \u0219i bcachefs-tools, cu utilitarul bcachefs care ruleaz\u0103 \u00een spa\u021biul utilizatorului, implement\u00e2nd comenzi pentru crearea (mkfs), montarea, recuperarea \u0219i verificarea FS. Pachetele sunt compilate pentru Debian, Ubuntu, Fedora, openSUSE, NixOS \u0219i Arch Linux. Modulul DKMS suport\u0103 lucrul cu kernel-uri Linux, \u00eencep\u00e2nd cu 6.16. <\/p>\n
Noua versiune a ad\u0103ugat func\u021bionalitatea «reconcile» (rebalance_v2), marcat\u0103 ca cea mai mare schimbare din ultimii doi ani \u00een FS. Spre deosebire de modul «rebalance» disponibil anterior, mecanismul «reconcile» permite reechilibrarea nu doar a datelor (de exemplu, replicarea mai multor copii pe diferite unit\u0103\u021bi de stocare), ci \u0219i a metadatelor \u00een FS (de exemplu, pentru a transfera metadatele dup\u0103 ad\u0103ugarea unei unit\u0103\u021bi de stocare suplimentare \u00een grup). \u00cen plus, reconcile este acum aplicabil pentru toate op\u021biunile de intrare\/ie\u0219ire, nu doar pentru opera\u021biuni de copiere \u00een fundal \u0219i comprimare. De asemenea, \u00een reconcile sunt automat luate \u00een considerare modific\u0103rile op\u021biunilor sau set\u0103rilor dispozitivelor \u0219i imediat se re-replic\u0103 datele \u0219i metadatele degradate. <\/p>\n
\u00cen reconcile sunt implicate indec\u0219i separa\u021bi pentru: opera\u021biuni de \u00eenalt\u0103 prioritate; optimizarea proces\u0103rii datelor pe unit\u0103\u021bile de stocare; datele programate pentru procesare, care nu pot fi \u00eenc\u0103 efectuate (de exemplu, din cauza lipsei de spa\u021biu). A fost ad\u0103ugat\u0103 suportul pentru crearea unui sistem de fi\u0219iere pe o singur\u0103 unitate \u00een modul de replicare dubl\u0103 (replicas=2) \u2014 \u00een aceast\u0103 configura\u021bie, ad\u0103ugarea unei a doua unit\u0103\u021bi va duce la replicarea automat\u0103 a datelor pe discului ad\u0103ugat, f\u0103r\u0103 a fi nevoie de vreo ac\u021biune din partea utilizatorului. <\/p>\n
Printre alte modific\u0103ri: <\/p>\n
Proiectul Bcachefs dezvolt\u0103 un sistem de fi\u0219iere care urm\u0103re\u0219te s\u0103 combine func\u021bionalitatea extins\u0103 caracteristic\u0103 Btrfs \u0219i ZFS cu nivelul de performan\u021b\u0103, fiabilitate \u0219i scalabilitate specific XFS. Bcachefs suport\u0103 func\u021bionalit\u0103\u021bi precum integrarea mai multor dispozitive \u00eentr-o parti\u021bie, layout-uri de stocare multilayer (stratul inferior cu date frecvent utilizate pe SSD-uri rapide, iar stratul superior cu date mai pu\u021bin necesare pe hard disk-uri), replicare (RAID 1\/10), caching, compresie transparent\u0103 a datelor (moduri LZ4, gzip \u0219i ZSTD), instantanee (snapshots), verificarea integrit\u0103\u021bii prin checksum-uri, posibilitatea de a stoca coduri de corec\u021bie a erorilor Reed-Solomon (RAID 5\/6), \u0219i stocarea informa\u021biilor \u00eentr-o form\u0103 criptat\u0103 (folosind ChaCha20 \u0219i Poly1305). \u00cen ceea ce prive\u0219te performan\u021ba, Bcachefs dep\u0103\u0219e\u0219te Btrfs \u0219i alte sisteme de fi\u0219iere bazate pe mecanismul Copy-on-Write, demonstr\u00e2nd viteze de operare apropiate de Ext4 \u0219i XFS. \u041a\u0435\u043d\u0442 \u041e\u0432\u0435\u0440\u0441\u0442\u0440\u0438\u0442 (Kent Overstreet)
