Title (EN) REBUILDING STORAGE VOLUMES
(FR) RECONSTRUCTION DE VOLUMES DE STOCKAGE
Abstract:
(EN) Some examples described herein relate to rebuilding storage volumes. In an example, storage volumes to be rebuilt may be identified. A rebuild priority may be assigned to each of the storage volumes by determining, for each of the storage volumes, whether a storage volume is a log volume. If a storage volume is a log volume, a highest first level rebuild priority may be assigned to the storage volume. If a storage volume is not a log volume, another rebuild priority may be assigned to the storage volume based on Redundant Array of Inexpensive Disks (RAID) level of the storage volume, number of failed physical disks that include data of the storage volume, and whether the storage volume is part of a data replication group. The storage volumes may be rebuild based on the rebuild priority assigned to each of the storage volumes.
(FR) Des exemples de l'invention se rapportent à la reconstruction de volumes de stockage. Dans un exemple, des volumes de stockage à reconstruire peuvent être identifiés. Une priorité de reconstruction peut être attribuée à chacun des volumes de stockage en déterminant, pour chacun des volumes de stockage, si un volume de stockage est un volume de journal. Si un volume de stockage est un volume de journal, une priorité de reconstruction de premier niveau le plus haut peut être attribuée au volume de stockage. Si un volume de stockage n'est pas un volume de journal, une autre priorité de reconstruction peut être attribuée au volume de stockage sur la base d'un niveau RAID (réseau redondant de disques indépendants) du volume de stockage, du nombre de disques physiques en panne qui incluent des données du volume de stockage et si le volume de stockage fait partie d'un groupe de réplication de données. Les volumes de stockage peuvent être reconstruits sur la base de la priorité de reconstruction attribuée à chacun des volumes de stockage.
