Abstract

resumo patente de invenção: "rastreamento de região suja de mídia não volátil". a presente invenção refere-se a um conjunto de armazenamento (por exemplo, uma série de drivers de disco rígido) pode experimentar uma falha, tal como uma perda de energia, uma pane de software, ou uma desconexão de um dispositivo de armazenamento, enquanto escritas no conjunto de armazenamento estão em andamento. a recuperação a partir de falha pode envolver varredura no conjunto de armazenamento para detectar e corrigir as inconsistências (por exemplo, espelhos de comparação de um conjunto de dados ou somas de verificação). no entanto, faltando informação sobre os locais de escritas pendentes para o conjunto de armazenamento durante a falha, este processo de "limpeza" pode envolver varredura de todo o conjunto de armazenamento, resultando em processos de recuperação prolongados. no presente documento, são apresentadas técnicas para rastrear escritas para o conjunto de armazenamento repartindo o conjunto de armazenamento em regiões de um tamanho de região (por exemplo, um gigabyte), e para armazenamento na descrição de meio de armazenamento não volátil de regiões "sujas" compreendendo as escritas em andamento. o processo de recuperação pós-falha pode então ser limitado às regiões identificadas como sujas. 20689597v1
