Abstract

A method, an apparatus, a device, and a medium for creating a thick-provisioned volume. The method includes: creating a thin volume; acquiring a current workload of a cluster; determining a volume filling thread quantity corresponding to the thin volume and a Quality of Service (QOS) policy based on the workload and a preset load threshold; filling the thin volume using a volume filling thread determined according to the volume filling thread quantity and the QOS policy, so as to complete the creation of a thick-provisioned volume. As such, determining the volume filling thread quantity and the QOS policy according to the current workload of the cluster and then filling the thin volume using the volume filling thread determined according to the volume filling thread quantity and the QOS policy so as to complete the creation of the thick-provisioned volume may reduce the influence of the creation of a thick-provisioned volume on core services of a cluster and thereby ensure the stability of the core services of the cluster.
