A method of operating block-based thin provisioning disk volumes in a system including a first storage system which is connected via a network to a second storage system, the method comprising: in response to a volume creation request to create a thin provisioning disk volume in the first storage system, recording in the first storage system attribute information of a block-based thin provisioning disk volume; storing disk blocks of the block-based thin provisioning disk volume as disk block files in a file system in the second storage system, the disk block files being read and written using HTTP-based protocol, each disk block file being identified by a file path: specifying a directory path for the block-based thin provisioning disk volume; and creating a directory for the block-based thin provisioning disk volume under the specified directory path; wherein creation of the directory in the second storage system is done by sending a HTTP request from the first storage system to the second storage system.
