Kent Overstreet ha pubblicato la versione 1.33.0 del file system Bcachefs. Il rilascio comprende due pacchetti: bcachefs-kernel-dkms con il modulo del kernel, costruito con il sistema DKMS (Dynamic Kernel Module Support), e bcachefs-tools con l'utilit\u00e0 bcachefs eseguita in spazio utente, che implementa comandi per la creazione (mkfs), il montaggio, il ripristino e la verifica del FS. I pacchetti sono stati compilati per Debian, Ubuntu, Fedora, openSUSE, NixOS e Arch Linux. Il modulo DKMS supporta il funzionamento con i kernel Linux a partire dalla versione 6.16. <\/p>\n
Nella nuova versione \u00e8 stata aggiunta la funzionalit\u00e0 \u00abreconcile\u00bb (rebalance_v2), contrassegnata come il pi\u00f9 grande cambiamento degli ultimi due anni nel filesystem. A differenza della precedente modalit\u00e0 \u00abrebalance\u00bb, il meccanismo \u00abreconcile\u00bb consente di effettuare il bilanciamento non solo dei dati (ad esempio, replicando pi\u00f9 copie su diversi supporti), ma anche dei metadati nel filesystem (ad esempio, per trasferire i metadati dopo l'aggiunta di un nuovo supporto al pool). Inoltre, reconcile \u00e8 ora applicabile a tutte le opzioni di input\/output, non solo alle operazioni di copia in background e compressione. In reconcile vengono anche considerati automaticamente i cambiamenti delle opzioni o delle impostazioni dei dispositivi e i dati e metadati degradati vengono immediatamente riprodotti. <\/p>\n
In reconcile, are used separate indexes for: high-priority operations; optimizing data processing on disk storage; data scheduled for processing that cannot currently be executed (for example, due to lack of space). Support has been added for creating a file system on a single drive in double replication mode (replicas=2) \u2014 in this configuration, adding a second drive will automatically replicate data to the added disk, without requiring any action from the user. <\/p>\n
Tra le altre modifiche: <\/p>\n
Il progetto Bcachefs sviluppa un file system mirato a combinare le funzionalit\u00e0 avanzate tipiche di Btrfs e ZFS, con i livelli di prestazioni, affidabilit\u00e0 e scalabilit\u00e0 caratteristici di XFS. Bcachefs supporta funzionalit\u00e0 come l'inclusione di pi\u00f9 dispositivi in un volume, layout a strati per i dispositivi di archiviazione (uno strato inferiore con dati frequentemente usati basati su SSD veloci, e uno strato superiore con dati meno richiesti da dischi rigidi), replicazione (RAID 1\/10), caching, compressione trasparente dei dati (modalit\u00e0 LZ4, gzip e ZSTD), snapshot, verifica dell'integrit\u00e0 tramite checksum, e la possibilit\u00e0 di memorizzare codici di correzione degli errori di Reed-Solomon (RAID 5\/6), oltre alla memorizzazione delle informazioni in forma criptata (utilizzando ChaCha20 e Poly1305). Per prestazioni, Bcachefs supera Btrfs e altri file system basati su Copy-on-Write, dimostrando velocit\u00e0 di funzionamento simile a Ext4 e XFS. \u041a\u0435\u043d\u0442 \u041e\u0432\u0435\u0440\u0441\u0442\u0440\u0438\u0442 (Kent Overstreet) \u043e\u043f\u0443\u0431\u043b\u0438\u043a\u043e\u0432\u0430\u043b \u0432\u044b\u043f\u0443\u0441\u043a \u0444\u0430\u0439\u043b\u043e\u0432\u043e\u0439 \u0441\u0438\u0441\u0442\u0435\u043c\u044b Bcachefs 1.33.0. \u0412\u044b\u043f\u0443\u0441\u043a \u043e\u0445\u0432\u0430\u0442\u044b\u0432\u0430\u0435\u0442 \u0434\u0432\u0430 \u043f\u0430\u043a\u0435\u0442\u0430: bcachefs-kernel-dkms \u0441 \u043c\u043e\u0434\u0443\u043b\u0435\u043c \u044f\u0434\u0440\u0430, \u0441\u043e\u0431\u0438\u0440\u0430\u0435\u043c\u044b\u043c \u043f\u0440\u0438 \u043f\u043e\u043c\u043e\u0449\u0438 \u0441\u0438\u0441\u0442\u0435\u043c\u044b DKMS (Dynamic Kernel Module Support), \u0438 bcachefs-tools \u0441 \u0437\u0430\u043f\u0443\u0441\u043a\u0430\u0435\u043c\u043e\u0439 \u0432 \u043f\u0440\u043e\u0441\u0442\u0440\u0430\u043d\u0441\u0442\u0432\u0435 \u043f\u043e\u043b\u044c\u0437\u043e\u0432\u0430\u0442\u0435\u043b\u044f \u0443\u0442\u0438\u043b\u0438\u0442\u043e\u0439 bcachefs, \u0440\u0435\u0430\u043b\u0438\u0437\u0443\u044e\u0449\u0435\u0439 \u043a\u043e\u043c\u0430\u043d\u0434\u044b \u0434\u043b\u044f \u0441\u043e\u0437\u0434\u0430\u043d\u0438\u044f (mkfs), \u043c\u043e\u043d\u0442\u0438\u0440\u043e\u0432\u0430\u043d\u0438\u044f, \u0432\u043e\u0441\u0441\u0442\u0430\u043d\u043e\u0432\u043b\u0435\u043d\u0438\u044f \u0438 \u043f\u0440\u043e\u0432\u0435\u0440\u043a\u0438 \u0424\u0421. \u041f\u0430\u043a\u0435\u0442\u044b \u0441\u043e\u0431\u0440\u0430\u043d\u044b \u0434\u043b\u044f Debian, Ubuntu, Fedora, openSUSE, NixOS \u0438 […]<\/p>\n","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[702],"tags":[],"class_list":["post-150906","post","type-post","status-publish","format-standard","hentry","category-novosti-interneta"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\n","aioseo_head_json":{"title":"\ud83e\udd47Rilascio del file system Bcachefs 1.33.0 | ProHoster","description":"Kent Overstreet ha pubblicato il rilascio del file system Bcachefs 1.33.0.
