A storage management technique involves: receiving a request for creating a virtual volume, the request at least indicating a size and a service level of the virtual volume; in response to the request, creating the virtual volume on a first storage device; storing metadata information of the virtual volume in a local database that is accessible to the first storage device, the metadata information at least comprising identification information of the virtual volume and identification information of the first storage device; and synchronizing the metadata information to at least one second storage device. Such a technique enables more flexible creation of virtual volumes on a cluster of storage device.
