Abstract

The invention belongs to the technical field of data storage, and discloses a request response method, a device, equipment and a computer readable storage medium. The method comprises the steps that if a current solid state disk replacement instruction is received, metadata in a current solid state disk is cached to a preset area of a mechanical disk; receiving an access request of an object storage service OSD, and determining a metadata identifier according to the access request; searching corresponding metadata in the current solid state disk based on the metadata identifier; if the corresponding metadata is not found, searching the corresponding metadata in a preset area of the mechanical disk based on the metadata identifier; and responding to the access request according to a searchresult in a preset area of the mechanical disk. By means of the mode, when a large amount of data is migrated, data loss is avoided, and the service access performance of the storage system is not affected.

Description

technical field [0001] The present invention relates to the technical field of data storage, in particular to a request response method, device, equipment and computer-readable storage medium. Background technique [0002] At present, in the distributed storage system, when the life of the solid state drive (SSD) is insufficient, the following methods are often used when replacing the SSD disk: stop all object storage services (Object storageDaemon, OSD) using the SSD, and then replace the SSD Pull out the disk, insert a new SSD disk, remove the OSD that uses the original SSD to store metadata from the cluster, and then use the new SSD disk to create a new OSD service, then add the new OSD to the cluster, and restore the OSD through the storage system data reconstruction function Data, so that the OSD resumes normal service. [0003] However, in the prior art, since the OSD metadata is persistently stored on the SSD, after the SSD is replaced, since this part of data does n...
