Title: Metadata storage method and system in distributed storage system, and storage medium
Inventor: Rao rong
IPC: G06F3/06
Filed: 2018-02-02
Abstract: Disclosed is a metadata storage method in a distributed storage system. In a distributed storage system, in a scenario where a metadata stripe composed of an EC algorithm realizes data reliability, a main data storage node backs up other metadata blocks in the metadata stripe. Since metadata blocks on a data storage node only need to be backed up on the main data storage node, in comparison with multiple replicas of all the metadata blocks, the storage space is reduced, and when a client accesses metadata, it is only necessary to access all the metadata blocks from the main data storage node, thus increasing the metadata access speed.
