Para o n\u00facleo Linux, foi proposto um conjunto de patches com a implementa\u00e7\u00e3o do dispositivo de bloco replicado distribu\u00eddo DRBD 9, permitindo a cria\u00e7\u00e3o de uma semelhan\u00e7a de um array RAID-1 formado por unidades espelhadas pela rede, conectadas a sistemas diferentes. O driver ser\u00e1 inicialmente testado na branch linux-next e preparado para integra\u00e7\u00e3o no n\u00facleo Linux 7.2. <\/p>\n

A vers\u00e3o antiga do DRBD est\u00e1 dispon\u00edvel no n\u00facleo desde a vers\u00e3o 2.6.33, lan\u00e7ada h\u00e1 16 anos. O c\u00f3digo dispon\u00edvel no n\u00facleo \u00e9 baseado na branch DRBD 8, que difere significativamente da branch DRBD 9, lan\u00e7ada em 2015 e incompat\u00edvel no n\u00edvel do protocolo. Assim, a branch DRBD 9 se desenvolveu como um m\u00f3dulo externo separado, n\u00e3o sincronizado com o m\u00f3dulo do n\u00facleo principal. A implementa\u00e7\u00e3o do DRBD no n\u00facleo foi mantida separadamente e est\u00e1 defasada em rela\u00e7\u00e3o \u00e0 base de c\u00f3digo atual do DRBD em 10-15 anos. Os patches propostos foram criados para eliminar essa lacuna. <\/p>\n

O DRBD permite combinar as unidades dos n\u00f3s do cluster em um \u00fanico armazenamento tolerante a falhas. Para aplicativos e sistemas, esse armazenamento se apresenta como um dispositivo de bloco id\u00eantico para todos os sistemas. Ao usar o DRBD, todas as opera\u00e7\u00f5es com o disco local s\u00e3o enviadas para outros n\u00f3s e sincronizadas com os discos de outras m\u00e1quinas. No caso de falha de um n\u00f3, o armazenamento continuar\u00e1 automaticamente a operar com os n\u00f3s restantes. Quando a disponibilidade do n\u00f3 com falha for restaurada, seu estado ser\u00e1 automaticamente atualizado para a vers\u00e3o atual. <\/p>\n

No cluster que forma o armazenamento, podem ser inclu\u00eddos at\u00e9 32 n\u00f3s, posicionados tanto na rede local quanto geograficamente dispersos. data centers<\/a>. A sincroniza\u00e7\u00e3o em reposit\u00f3rios t\u00e3o ramificados \u00e9 realizada na forma de uma rede mesh \u2014 os dados se espalham ao longo da corrente de n\u00f3 a n\u00f3. A replica\u00e7\u00e3o dos n\u00f3s pode ser realizada tanto em modo s\u00edncrono quanto ass\u00edncrono. Por exemplo, os n\u00f3s localmente instalados podem utilizar replica\u00e7\u00e3o s\u00edncrona, enquanto para n\u00f3s em locais remotos pode ser utilizada replica\u00e7\u00e3o ass\u00edncrona com compress\u00e3o e criptografia adicionais no tr\u00e1fego. <\/p>\n

A ramifica\u00e7\u00e3o DRBD 9 se destaca pela abstra\u00e7\u00e3o do n\u00edvel de transporte, permitindo a implementa\u00e7\u00e3o de canais de comunica\u00e7\u00e3o n\u00e3o apenas sobre TCP\/IP, mas tamb\u00e9m utilizando RDMA\/Infiniband. Comparado ao funcionamento sobre uma rede IP tradicional, a integra\u00e7\u00e3o de acesso direto \u00e0 mem\u00f3ria de outro computador atrav\u00e9s do RDMA (Acesso Direto Remoto \u00e0 Mem\u00f3ria) possibilitou dobrar a performance de replica\u00e7\u00e3o enquanto reduz a carga no CPU em 50%. O tamanho m\u00e1ximo do armazenamento sincronizado foi aumentado para 32 n\u00f3s. No DRBD 9, tamb\u00e9m foi alterada a l\u00f3gica de ressincroniza\u00e7\u00e3o dos n\u00f3s, reformulado o mecanismo de bloqueio, adicionada a suportabilidade de espa\u00e7o de nomes de rede (network namespace), assegurada a defini\u00e7\u00e3o autom\u00e1tica do status do n\u00f3 com base na atividade, e implementada a suportabilidade de commits em duas fases e a distribui\u00e7\u00e3o de atualiza\u00e7\u00f5es de forma n\u00e3o bloqueante. \"Foi
