Na base de c\u00f3digo «ZFS on Linux<\/a><\/noindex>«, desenvolvida sob a \u00e9gide do projeto OpenZFS<\/a><\/noindex> como uma implementa\u00e7\u00e3o de refer\u00eancia do ZFS, foram aceitas<\/a><\/noindex> mudan\u00e7as que adicionam suporte<\/a><\/noindex> do sistema operacional FreeBSD. O c\u00f3digo adicionado ao «ZFS on Linux» foi testado nas branches FreeBSD 11 e 12. Dessa forma, os desenvolvedores do FreeBSD n\u00e3o precisam mais manter sua pr\u00f3pria ramifica\u00e7\u00e3o sincronizada do «ZFS on Linux» e o desenvolvimento de todas as altera\u00e7\u00f5es relacionadas ao FreeBSD ser\u00e1 realizado no projeto principal. Al\u00e9m disso, a funcionalidade na branch principal do «ZFS on Linux» no processo de desenvolvimento ser\u00e1 testada no sistema de integra\u00e7\u00e3o cont\u00ednua. <\/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>» (ZoL), em torno do qual toda a atividade relacionada ao desenvolvimento do ZFS se concentrou recentemente. A migra\u00e7\u00e3o foi mencionada devido \u00e0 estagna\u00e7\u00e3o da base de c\u00f3digo ZFS do projeto Illumos (um fork do OpenSolaris), que anteriormente era utilizada como base para transferir as altera\u00e7\u00f5es relacionadas ao ZFS para o FreeBSD. A principal contribui\u00e7\u00e3o para o suporte da base de c\u00f3digo ZFS no Illumos at\u00e9 recentemente foi feita pela empresa Delphix, que desenvolve o sistema operacional DelphixOS<\/a><\/noindex> (fork do Illumos). Dois anos atr\u00e1s, a empresa Delphix decidiu migrar para o «ZFS on Linux», 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 «ZFS on Linux», que agora \u00e9 considerado a implementa\u00e7\u00e3o principal. OpenZFS<\/a><\/noindex>.<\/p>\n

Os desenvolvedores do FreeBSD decidiram seguir o exemplo geral e n\u00e3o tentar se manter ligados ao Illumos, j\u00e1 que essa implementa\u00e7\u00e3o j\u00e1 est\u00e1 muito defasada em funcionalidade e demanda muitos recursos para manter o c\u00f3digo e transferir mudan\u00e7as. O «ZFS on Linux» agora \u00e9 visto como o principal projeto colaborativo para o desenvolvimento do ZFS. Entre as funcionalidades dispon\u00edveis no «ZFS on Linux» para o FreeBSD, mas ausentes na implementa\u00e7\u00e3o do ZFS do Illumos, est\u00e3o: modo multihost (MMP<\/a><\/noindex>, Prote\u00e7\u00e3o de M\u00faltiplos Modificadores), sistema de cotas avan\u00e7adas, criptografia de conjuntos de dados, sele\u00e7\u00e3o separada de classes de aloca\u00e7\u00e3o de blocos, uso de instru\u00e7\u00f5es de vetor para acelerar a implementa\u00e7\u00e3o do RAIDZ e o c\u00e1lculo de somas de verifica\u00e7\u00e3o, ferramentas de linha de comando aprimoradas, corre\u00e7\u00e3o de muitos bugs relacionados a condi\u00e7\u00f5es de corrida e bloqueios.<\/p>\n
