Abstract

Volume expansion in a storage management system coupled to a storage system via a network is performed. A request for expanding an original volume of a first cluster located at the storage system to a target volume is received. A second cluster located at the storage system is obtained. A remaining storage space of the second cluster is larger than a storage space required by the target volume. The storage system is instructed to create the target volume at the second cluster, and the original volume is expanded to the target volume.

Description

technical field [0001] Embodiments of the present invention generally relate to virtualization storage technologies, and more specifically, relate to a method and device for volume expansion in a storage management system. Background technique [0002] Virtualized storage technology makes storage resources a huge "storage pool" by separating the logical image of storage resources from physical storage. One or more virtual volumes of different sizes are established in the storage pool according to specific needs. These virtual volumes It is dynamically allocated to various application servers on the storage network, so as to achieve the purpose of making full use of storage capacity, centrally managing storage, and reducing storage costs, which can meet the needs of rapid growth of enterprise data. [0003] With the development of cloud computing technology, cloud storage has also become a rapidly developing technology. The storage layer of cloud storage is an integrated sol...
