The invention discloses a startup method of a distributed file system storage unit. The method comprises: when a main process of any storage unit in the distributed file system is started, determiningthat any storage unit is a target unit and a storage node to which the target unit belongs is a target node; judging whether the startup of the main process of the target unit is the self-startup caused by the startup of the target node, if so, controlling all the storage units on the target node to report the respective state information to the control module at a predetermined time, if not, determining that the time control of the state information reporting is not necessary. Compared with the prior art, the storage unit list is updated irregularly many times during a period of time when the storage node starts, the update frequency of the storage unit list is effectively reduced, the service efficiency of the storage unit is greatly improved, and the system performance of the distributed file system is improved.
Description
technical field [0001] The present invention relates to the technical field of distributed file systems, and more specifically, to a method, device, equipment and computer-readable storage medium for starting a storage unit of a distributed file system. Background technique [0002] The distributed file system includes multiple storage nodes, and each storage node includes multiple storage units. Generally, a storage unit corresponds to a physical disk (such as STAT hard disk, SAS hard disk, SSD solid-state hard disk, etc.) for data storage. . [0003] When a storage node in the distributed file system is shut down and then restarted, multiple storage units located on the storage node will start randomly and out of order, and report their own status to the monitoring module. The information of its own state updates the corresponding storage unit list, which will cause the storage unit list of the distributed file system to be updated multiple times and irregularly during th...
