Abstract

The invention discloses a storage pool creation method. The method comprises the following steps: acquiring a plurality of nodes under default root; judging whether to perform data isolation or not; in response to data isolation, obtaining the type of a fault domain; in response to the fact that the fault domain is rack, creating the rack and adding a plurality of nodes in the plurality of nodes into the created rack; constructing a crush structure of a root / trace / host level; and binding a preset protection strategy with the cuss structure, and creating a storage pool by utilizing the cuss structure bound with the protection strategy. The invention further discloses a system, computer equipment and a readable storage medium. According to the scheme provided by the invention, isolation is carried out based on the storage pool when the storage pool is created, so that no intersection exists between a disk OSD and an old storage node, the independence of part of storage data is ensured, and the safety and the read-write performance of a client on the storage data are correspondingly improved.

Description

technical field [0001] The present invention relates to the field of clusters, in particular to a storage pool creation method, system, device and storage medium. Background technique [0002] With the wave of global informatization, network and cloud computing have been closely related to people's lives. With the advent of mobile Internet and artificial intelligence, data information has grown exponentially, which puts high demands on the performance of storage devices. PB-level massive data is stored in the backend of the device, and data storage becomes very time-consuming and difficult. Not only must a large amount of new structured and unstructured data be stored, but also massive historical data must be stored. The storage time may take years. For calculation units, such as WeChat, QQ and other data, such as a large number of customer information in banks, etc., it is difficult to ensure sufficient data storage space only by relying on existing equipment information, s...
