AI Technical Summary
Technical Problem
The limited number of faulty disks in the existing storage pool leads to poor performance and an inability to effectively cope with multiple node failures.
Method used
By virtualizing the storage nodes, multiple virtualized nodes are formed. Disks are allocated to each virtualized node according to the disk allocation method of non-uniform memory access nodes, so that the difference in the number of disks among the virtualized nodes is at most 1, and the number of disks across nodes is minimized.
Benefits of technology
This improves the fault tolerance of the storage pool, allowing for more failed disks, while reducing cross-node data transfer and enhancing the overall performance of the storage pool.

Abstract
This invention discloses a storage pool creation method, apparatus, device, and computer-readable storage medium, applied in the field of distributed storage technology. The method includes: virtualizing storage nodes to obtain a set number of virtualized nodes; the set number being greater than 1; determining the non-uniform memory access nodes corresponding to the virtualized nodes; and allocating disks to each virtualized node using a disk allocation method based on the disks corresponding to each non-uniform memory access node, thereby obtaining a target storage pool. The disk allocation method is one that maximizes the difference in the number of disks corresponding to each virtualized node to 1, and minimizes the number of disks across nodes. Since one storage node corresponds to multiple virtualized nodes, the maximum number of disk failures allowed under the same redundancy strategy becomes greater. The disk allocation method ensures storage pool balance and reduces cross-node transmission.
