Abstract

Un grupo de almacenamiento (por ejemplo, una disposición de unidades de disco duro) puede experimentar una falla, tal como una pérdida de e nergía, u n choque de software, una desconexión de un dispositivo de almacenamiento, mientras las escrituras para el grupo de almacenamiento están en progreso. La recuperación de la falla puede involucrar escanear el grupo de almacenamiento para detectar y corregir inconsistencias (por ejemplo, comparar reflejos de un grupo de datos o sumas de verificación de prueba). Sin embargo, al carecer de información sobre las ubicaciones de escrituras pendientes al grupo de almacenamiento durante la falla, este procedimiento de "limpieza" puede involucrar escanear todo el grupo de almacenamiento, que resulta en procedimientos de recuperación prolongada. Aquí se presentan técnicas para rastrear escrituras para el grupo de almacenamiento al distribuir el grupo de almacenamiento en regiones de un tamaño de región (por ejemplo, 1 gigabyte), y al almacenar en descriptores de medio de almacenamiento no volátil de regiones "sucias" que comprenden escrituras en progreso. El procedimiento de recuperación post-falla entonces puede limitarse a las regiones identificadas como sucias.
