Foi lan\u00e7ado o Stratis 3.0, desenvolvido pela Red Hat e pela comunidade Fedora, para unificar e simplificar as ferramentas de configura\u00e7\u00e3o e gerenciamento de pools de um ou mais dispositivos de armazenamento locais. O Stratis oferece funcionalidades como aloca\u00e7\u00e3o din\u00e2mica de espa\u00e7o de armazenamento, snapshots, garantia de integridade e cria\u00e7\u00e3o de camadas para caching. O suporte ao Stratis est\u00e1 integrado nas distribui\u00e7\u00f5es Fedora e RHEL a partir das vers\u00f5es Fedora 28 e RHEL 8.2. O c\u00f3digo do projeto \u00e9 distribu\u00eddo sob a licen\u00e7a MPL 2.0. <\/p>\n

O sistema, em grande parte, reflete as capacidades avan\u00e7adas de gerenciamento de parti\u00e7\u00f5es do ZFS e Btrfs, mas \u00e9 implementado como uma camada (demon stratisd) que opera sobre o subsistema device-mapper do n\u00facleo Linux (usando os m\u00f3dulos dm-thin, dm-cache, dm-thinpool, dm-raid e dm-integrity) e o sistema de arquivos XFS. Diferentemente 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 espec\u00edficos do n\u00facleo. O projeto \u00e9 inicialmente apresentado como n\u00e3o exigindo qualifica\u00e7\u00e3o de especialista em sistemas de armazenamento para administra\u00e7\u00e3o. <\/p>\n

Para gerenciamento, \u00e9 fornecida uma API D-Bus e uma ferramenta de linha de comando cli. O funcionamento do 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 diversos HDDs, SSDs e dispositivos NVMe. Com um \u00fanico disco no pool, o Stratis permite o uso de parti\u00e7\u00f5es l\u00f3gicas com suporte a snapshots para reverter altera\u00e7\u00f5es. Ao adicionar v\u00e1rios dispositivos ao pool, \u00e9 poss\u00edvel a combina\u00e7\u00e3o l\u00f3gica dos dispositivos em uma \u00e1rea cont\u00ednua. Funcionalidades como RAID, compress\u00e3o de dados, deduplica\u00e7\u00e3o e organiza\u00e7\u00e3o de toler\u00e2ncia a falhas ainda n\u00e3o s\u00e3o suportadas, mas est\u00e3o planejadas para o futuro. <\/p>\n

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

A mudan\u00e7a significativa na numera\u00e7\u00e3o da vers\u00e3o se deve \u00e0 altera\u00e7\u00e3o da interface de gerenciamento via D-Bus e ao fim do suporte para as interfaces FetchProperties, em favor do uso de propriedades e m\u00e9todos baseados em D-Bus. A nova vers\u00e3o tamb\u00e9m adicionou verifica\u00e7\u00e3o de regras udev utilizando libblkid antes de fazer altera\u00e7\u00f5es, reformulou o tratamento de eventos do DeviceMapper, alterou a representa\u00e7\u00e3o interna dos manipuladores de erros, revisou o c\u00f3digo para reverter altera\u00e7\u00f5es (rollback) e permitiu a especifica\u00e7\u00e3o do tamanho l\u00f3gico ao criar o sistema de arquivos. No framework Clevis, usado para criptografar e descriptografar automaticamente dados em parti\u00e7\u00f5es de disco, foram empregados hashes SHA-256 em vez de SHA-1. Agora \u00e9 poss\u00edvel alterar a frase da senha e regenerar os v\u00ednculos ao Clevis.
