Implementa\u00e7\u00e3o do sistema de arquivos ZFS no ramo principal do FreeBSD (HEAD) traduzido<\/a><\/noindex> para o uso do c\u00f3digo OpenZFS<\/a>, desenvolvendo a base de c\u00f3digo \u00abZFS on Linux<\/a><\/noindex>\u00bb como a refer\u00eancia padr\u00e3o para ZFS. Na primavera, o suporte ao FreeBSD foi transferido para o projeto principal OpenZFS, ap\u00f3s o qual o desenvolvimento de todas as mudan\u00e7as relacionadas ao FreeBSD continuou, e os desenvolvedores do FreeBSD obtiveram a capacidade de transferir rapidamente para o sistema todas as inova\u00e7\u00f5es desenvolvidas pelo projeto OpenZFS. <\/p>\n

Entre os recursos que se tornaram dispon\u00edveis no FreeBSD ap\u00f3s a transi\u00e7\u00e3o para o OpenZFS: um sistema de quotas expandido, criptografia de conjuntos de dados, sele\u00e7\u00e3o separada de classes de aloca\u00e7\u00e3o, utiliza\u00e7\u00e3o de instru\u00e7\u00f5es de processador vetoriais para acelerar a implementa\u00e7\u00e3o do RAIDZ e o c\u00e1lculo de somas de verifica\u00e7\u00e3o, suporte ao algoritmo de compress\u00e3o ZSTD, modo multihost (MMP<\/a><\/noindex>, Prote\u00e7\u00e3o Multi Modifier), ferramentas de linha de comando aprimoradas, corre\u00e7\u00e3o de muitos erros relacionados a condi\u00e7\u00f5es de corrida e bloqueios.<\/p>\n

Vale lembrar que, em dezembro de 2018, os desenvolvedores do FreeBSD apresentaram iniciativa<\/a><\/noindex> migrar para a implementa\u00e7\u00e3o do ZFS do projeto \u201cZFS on Linux<\/a><\/noindex>\u00bb (ZoL), em torno do qual toda a atividade relacionada ao desenvolvimento do ZFS se concentrou recentemente. O motivo da migra\u00e7\u00e3o foi a estagna\u00e7\u00e3o da base de c\u00f3digo do ZFS do projeto Illumos (fork do OpenSolaris), que anteriormente era usada como base para a transfer\u00eancia de mudan\u00e7as relacionadas ao ZFS para o FreeBSD. <\/p>\n

A principal contribui\u00e7\u00e3o para o suporte da base de c\u00f3digo ZFS no Illumos at\u00e9 recentemente era feita pela empresa Delphix, que desenvolve o sistema operacional DelphixOS<\/a><\/noindex> (fork do Illumos). H\u00e1 tr\u00eas anos, a empresa Delphix decidiu migrar para \u00abZFS on Linux\u00bb, o que levou \u00e0 estagna\u00e7\u00e3o do ZFS do projeto Illumos e \u00e0 concentra\u00e7\u00e3o de toda a atividade de desenvolvimento no projeto \u00abZFS on Linux\u00bb, que agora \u00e9 visto como a implementa\u00e7\u00e3o principal. OpenZFS<\/a><\/noindex>.<\/p>\n

Os desenvolvedores do FreeBSD decidiram seguir o exemplo geral e n\u00e3o tentar se apegar ao Illumos, uma vez que essa implementa\u00e7\u00e3o j\u00e1 est\u00e1 muito atrasada em funcionalidade e requer muitos recursos para manuten\u00e7\u00e3o do c\u00f3digo e transfer\u00eancia de mudan\u00e7as. O OpenZFS, baseado no \u00abZFS on Linux\u00bb, agora \u00e9 considerado um \u00fanico projeto colaborativo para o desenvolvimento do ZFS. <\/p>\n
