Abstract: A method for data reconstruction includes: obtaining a data migration list, where the data migration list indicates a partition with data to be migrated on a storage node with data to be migrated; generating a data migration task according to the data migration list and routing table information, where the routing table information indicates correspondence between a storage node in a cluster and a partition; and concurrently executing data migration tasks of a storage node in the cluster to reconstruct data. In addition, a device for data reconstruction and a storage system are further provided accordingly.

Abstract: The present disclosure relates to the field of information technology, and in particular, to a block storage-based data processing method, apparatus, and system. The block storage-based data processing method provided in embodiments of the present disclosure is applied in a system including at least two storage nodes, each storage node including a CPU, a cache medium, and a non-volatile storage medium, and the cache medium in all the storage nodes forming a cache pool. According to the method, after receiving a data operation request sent by a client, a service processing node sends the data operation request to a corresponding storage node in the system according to a logical address carried in the data operation request, so that the data operation request is processed in the cache medium of the storage node under control of the CPU of the storage node.

Abstract: This application discloses a data processing method in a storage system and the storage system, and relates to the field of data storage technologies. In this application, a client sends a data block in a stripe and metadata of the data block to a data storage node, and sends the metadata of the data block and a parity block to a parity storage node, to back up the metadata of the data block on the parity storage node. This reduces write operation time.

Abstract: Embodiments of the present invention provide a method and a system for sharing a storage resource, where storage resources of a hard disk and a storage array are divided into multiple storage partitions and the multiple storage partitions form a shared storage resource pool, a read-write control module is allocated to each storage partition, and global partition information is generated to record a correspondence between each storage partition in the shared storage resource pool and the read-write control module. The embodiments of the present invention implement fast and simple integration of heterogeneous storage resources, and therefore can efficiently use various storage resources, save cost, and avoid a resource waste.
