Abstract

Embodiments of the present invention provide a cloud storage-based metadata management method and apparatus. The metadata management method comprises that: after determining that a first storage medium is accessed, a first storage node acquires a first storage medium identifier of the first storage medium; according to the first storage medium identifier, whether the first storage node stores thefirst metadata corresponding to the first storage medium is queried; and if so, the management node is notified to set the state of the first storage medium as to be accessed, so that data stored in the first storage medium is queried by the first metadata. According to the embodiments of the present invention, the acquisition operation of the metadata of the accessed storage medium can be reduced, and the storage efficiency of the metadata of the storage medium can be improved.

Description

technical field [0001] The present invention relates to the technical field of cloud storage, in particular to a metadata management method and device based on cloud storage. Background technique [0002] The cloud storage system includes a management node for managing the storage nodes and a storage node for storing data, wherein the storage nodes are connected to a storage medium, and the storage medium is used to provide storage space for the storage nodes to store data. In the cloud storage system, when the storage medium is connected to the storage node each time, the storage node will read the metadata corresponding to the connected storage medium, and store the read metadata locally in the storage node, wherein, the The metadata corresponding to the storage medium includes basic attribute information of the storage medium and basic attribute information of data stored in the storage medium. The above-mentioned storage node reports the corresponding relationship betwe...
