Publicado<\/a><\/noindex> lan\u00e7amento do projeto Stratis 2.2<\/a><\/noindex>, desenvolvido pela empresa Red Hat e pela comunidade Fedora para unificar e simplificar as ferramentas de configura\u00e7\u00e3o e gerenciamento de um ou mais dispositivos de armazenamento local. Stratis oferece recursos como aloca\u00e7\u00e3o din\u00e2mica de espa\u00e7o em armazenamento, snapshots, garantia de integridade e cria\u00e7\u00e3o de camadas para cache. O c\u00f3digo do projeto \u00e9 escrito na linguagem Rust e \u00e9 distribu\u00eddo<\/a><\/noindex> sob a licen\u00e7a MPL 2.0.<\/p>\n

O sistema em muitos aspectos replica as capacidades avan\u00e7adas de gerenciamento de parti\u00e7\u00f5es do ZFS e Btrfs, mas \u00e9 implementado como uma camada (daemon stratisd<\/a><\/noindex>), que roda sobre a subsistema device-mapper do kernel Linux (utilizando os m\u00f3dulos dm-thin, dm-cache, dm-thinpool, dm-raid e dm-integrity) e o sistema de arquivos XFS. Ao contr\u00e1rio do ZFS e Btrfs, os componentes do Stratis operam apenas no espa\u00e7o do usu\u00e1rio e n\u00e3o requerem a carga de m\u00f3dulos de kernel espec\u00edficos. O projeto \u00e9 inicialmente apresentado como um que n\u00e3o requer<\/a><\/noindex> qualifica\u00e7\u00f5es de especialista em sistemas de armazenamento para administra\u00e7\u00e3o. <\/p>\n

Para gerenciamento, \u00e9 fornecido um API D-Bus e uma ferramenta cli<\/a><\/noindex>.
\nO Stratis foi testado com dispositivos de bloco baseados em LUKS (parti\u00e7\u00f5es criptografadas), mdraid, dm-multipath, iSCSI, volumes l\u00f3gicos LVM, bem como com v\u00e1rios HDDs, SSDs e dispositivos NVMe. Com a presen\u00e7a de um \u00fanico disco no pool, o Stratis permite o uso de parti\u00e7\u00f5es l\u00f3gicas com suporte a snapshots para reverter mudan\u00e7as. Ao adicionar v\u00e1rios dispositivos ao pool, surge a possibilidade de combinar os dispositivos de forma l\u00f3gica em uma \u00e1rea cont\u00ednua. Recursos como
\nRAID, compress\u00e3o de dados, deduplica\u00e7\u00e3o e organiza\u00e7\u00e3o de toler\u00e2ncia a falhas ainda n\u00e3o s\u00e3o suportados, mas est\u00e3o planejados para o futuro.<\/p>\n

\"Lan\u00e7amento<\/a><\/noindex><\/center><\/p>\n

Em na vers\u00e3o 2.2<\/a><\/noindex> novas variantes de interfaces D-Bus foram adicionadas para a extra\u00e7\u00e3o de propriedades (FetchProperties), gerenciamento (Manager) e intera\u00e7\u00e3o com dispositivos de bloco (Blockdev). Foi adicionada a capacidade de informar sobre a ocorr\u00eancia de eventos de conex\u00e3o e desconex\u00e3o de interfaces (InterfacesAdded e InterfacesRemoved) atrav\u00e9s do D-Bus. Na ferramenta stratis-cli foram melhorados<\/a><\/noindex> os cen\u00e1rios de autocompletar para bash.<\/p>\n
