AI Technical Summary

⚠Technical Problem

Distributed storage systems cannot adaptively adjust redundancy parameters in the event of a failure, resulting in unrecoverable data and service interruption, making it difficult to meet the requirements of business continuity and rapid recovery.

⚗Method used

By dynamically creating a second-level storage pool and adjusting the redundant parameter group, data is written to the second-level storage pool. Data writing continues when a storage node fails, and the data is smoothly migrated back to the first-level storage pool after the node recovers, thus achieving continuous data writing and service continuity.

🎯Benefits of technology

In the event of storage node failure, it ensures continuous data writing and uninterrupted service, enables automatic reclamation of storage resources and smooth recovery of system status, and improves the system's service continuity and fault recovery efficiency.

Abstract

The application relates to a storage pool management method and device of a distributed storage system, a storage medium and electronic equipment. The method comprises the following steps: acquiring state information of each storage node; determining a first redundancy parameter group based on the number of storage nodes and a preset fault tolerance strategy, and creating a first layer storage pool; in response to at least one storage node being in an unavailable state, determining a second redundancy parameter group based on the remaining available storage nodes and the preset fault tolerance strategy, creating a second layer storage pool according to the second redundancy parameter group, storing target data into the second layer storage pool, in response to the storage node recovering to an available state, judging whether the target data in the second layer storage pool meets a preset migration condition, and if the preset migration condition is met, migrating the target data to the first layer storage pool; and if the target data does not exist in the second layer storage pool and the first layer storage pool meets a preset read-write condition, deleting the second layer storage pool. By the method, system service continuity and fault recovery efficiency can be improved.
