O lan\u00e7amento abrange dois pacotes: bcachefs-kernel-dkms com um m\u00f3dulo de kernel, compilado usando o sistema DKMS (Dynamic Kernel Module Support), e bcachefs-tools com a utilidade bcachefs execut\u00e1vel no espa\u00e7o do usu\u00e1rio, que implementa comandos para cria\u00e7\u00e3o (mkfs), montagem, recupera\u00e7\u00e3o e verifica\u00e7\u00e3o do FS. Os pacotes foram compilados para Debian, Ubuntu, Fedora, openSUSE, NixOS e Arch Linux. O m\u00f3dulo DKMS suporta n\u00facleos Linux a partir da vers\u00e3o 6.16.    <\/p>\n<p>Na nova vers\u00e3o:  <\/p>\n<ul>\n<li class=\"l\"> Apoio a c\u00f3digos de corre\u00e7\u00e3o de erros foi estabilizado e declarado pronto para uso geral, permitindo a recupera\u00e7\u00e3o de dados corrompidos, similar ao RAID 5\/6. A implementa\u00e7\u00e3o \u00e9 baseada na codifica\u00e7\u00e3o de Reed-Solomon, capaz de corrigir at\u00e9 N erros em um stripe na presen\u00e7a de N blocos redundantes. O restabelecimento autom\u00e1tico de stripes degradados foi assegurado. Adicionada a possibilidade de usar c\u00f3digos de recupera\u00e7\u00e3o em configura\u00e7\u00f5es com unidades de tamanhos diferentes.\n<li class=\"l\"> Suporte para o kernel Linux 7.0 em desenvolvimento foi adicionado.\n<li class=\"l\"> Novos comandos foram implementados: &#171;subvolume list&#187; para exibir subvolumes com filtragem e classifica\u00e7\u00e3o; &#171;subvolume list-snapshots&#187; para mostrar snapshots em forma hier\u00e1rquica&#8217;; &#171;subvolume reflink-option-propagate&#187; para aplicar par\u00e2metros de entrada e sa\u00edda de arquivo, como compacta\u00e7\u00e3o, soma de verifica\u00e7\u00e3o, n\u00famero de r\u00e9plicas e lista de dispositivos de destino, aos extents do arquivo.\n<li class=\"l\"> A opera\u00e7\u00e3o de retrocesso (rewind) do log foi estabilizada.\n<li class=\"l\"> A recupera\u00e7\u00e3o autom\u00e1tica foi assegurada ao usar dispositivos com suporte incorreto para os comandos de descarregamento de opera\u00e7\u00f5es de grava\u00e7\u00e3o em cache (flush e FUA).\n<li class=\"l\"> A recupera\u00e7\u00e3o ap\u00f3s uma termina\u00e7\u00e3o inesperada foi acelerada.\n<li class=\"l\"> A performance do FS cobrindo m\u00faltiplos dispositivos foi aumentada.\n<li class=\"l\"> As utilit\u00e1rios bcachefs executados no espa\u00e7o do usu\u00e1rio foram reescritos na linguagem Rust. No futuro, planeja-se reescrever tamb\u00e9m os componentes do FS que funcionam a n\u00edvel de kernel em Rust. O trabalho come\u00e7ou utilizando a ferramenta Verus para verifica\u00e7\u00e3o formal do c\u00f3digo em Rust.    <\/ul>\n<p>O projeto Bcachefs est\u00e1 desenvolvendo um sistema de arquivos que visa combinar a funcionalidade avan\u00e7ada caracter\u00edstica do Btrfs e ZFS com o n\u00edvel de desempenho, confiabilidade e escalabilidade t\u00edpico do XFS. O Bcachefs suporta recursos como a inclus\u00e3o de v\u00e1rios dispositivos em uma parti\u00e7\u00e3o, arranjos de armazenamento em camadas (camada inferior com dados de uso frequente em SSDs r\u00e1pidos, e camada superior com dados menos exigidos de hard disks), replica\u00e7\u00e3o (RAID 1\/10), cache, compress\u00e3o de dados transparente (modos LZ4, gzip e ZSTD), snapshots, verifica\u00e7\u00e3o de integridade por somas de verifica\u00e7\u00e3o, c\u00f3digos de corre\u00e7\u00e3o de erros, e armazenamento de informa\u00e7\u00f5es de forma criptografada (utilizando ChaCha20 e Poly1305).<br \/>\n<br \/>Fonte: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=65003\">opennet.ru<\/a>
