Abstract

The present invention provides a storage system capacity statistics method, device, storage medium and equipment. The method includes: if the storage volume of the storage system receives a write request, write the corresponding data into the storage pool to obtain the PBA, and write the PBA and the The LBAs corresponding to the data form the first key-value pair and the second key-value pair respectively, and send to the metadata management module; the first insertion request for inserting the first key-value pair is sent to the first B+ tree by it, and sends to the first B+ tree The second B+ tree sends the second insert request for inserting the second key-value pair; judges whether there is an LBA of the first key-value pair in the first B+ tree; if it does not exist, inserts the first key-value pair into the first B+ tree, and Add one to the first key number to increase the capacity of the statistical storage volume by one granularity; judge whether there is a PBA of the second key-value pair in the second B+ tree; if not exist, insert the second key-value pair into the second B+ tree, and Add one to the second key number to increase the capacity of the statistical storage pool by one granularity. The invention can accurately count the capacity of storage volumes and storage pools.

Description

technical field [0001] The invention relates to the field of storage technology, in particular to a storage system capacity statistics method, device, storage medium and equipment. Background technique [0002] Metadata (Mete data) refers to data describing data (data about data), which can be understood as data that is broader than the general meaning of data. It not only represents the type, name, value and other information of data, but also further provides The context information of the data, such as the domain to which the data belongs, the source of the data, and so on. In a data storage system, metadata is the basis of information storage and the smallest unit of data. In recent years, with the development of information technology, massive data has been generated, but how to effectively manage and organize these massive data has become a prominent problem. For a large amount of stored data, querying and analyzing the data content and meaning of the data can make m...
