Problems solved by technology

[0005] The object of the present invention is achieved in the following manner. The server used in the method is based on the Linux operating system and is suitable for servers in a single cluster system. The method can effectively utilize the resources in the cluster and format blocks in a server. When the device fails or the load of the node server is too heavy, it automatically finds other servers in the cluster to format the block device, which solves the defect that the block device cannot be formatted on one server

Embodiment Construction

[0021] Referring to the accompanying drawings, the content of the present invention will be described with a specific example to realize the process of this system structure. Based on the Linux operating system, it is suitable for servers in a single cluster system to effectively use the node resources in the cluster. When a server fails to format the block device or the node server is overloaded, it will automatically search for other server nodes in the cluster for block processing. The format of the device solves the defect that the block device cannot be formatted or formatted slowly on one server. The system includes: cluster management module (1), block device management module (2), block device format monitoring module (3 ), scheduling processing module (4), where:

[0022] The cluster management module (1) is responsible for providing users with various external services, and at the same time, it can realize the interactive function between the cluster and the back-end...

Abstract

The invention provides a scheduling method for formatting a shared block device of a cluster storage system. Based on the Linux operating system, the method is appropriate for effectively using node resources effectively in a server of a single cluster system to automatically search for other server nodes in the cluster for formatting the block device when the formatting block device of one server fails or the node server is overload, thereby solving the deficiency that the block device cannot be formatted or slowly formatted on one server.

Description

technical field [0001] The present invention is a block device formatting and dispatching method, which is usually used for abnormal processing of each node in the cluster when formatting block devices, and can ensure the completion of block device formatting to the greatest extent. Background technique [0002] At present, the block device formatting operation of the cluster storage system is mainly to map multiple block devices to the cluster nodes through the back-end physical storage device, and then the cluster nodes format the mapped block devices. However, as the capacity of the block devices increases, The larger the value, the inconsistent load of each node in the cluster may lead to a longer and longer time to format the disk, or if one or some nodes in the cluster are abnormal, it may also cause the cluster node to fail to format the block device, which greatly Reduced the efficiency of cluster system formatting. [0003] Therefore, how to provide a method to for...
