Abstract
In one embodiment, 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 comprises, 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 the block-based thin provisioning disk volume; specifying a directory path for the block-based thin provisioning disk volume in a file system in the second storage system; and creating a directory for the block-based thin provisioning disk volume under the specified directory path.
Claims20
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;
- specifying a directory path for the block-based thin provisioning disk volume in a file system in the second storage system;
- and
- creating a directory for the block-based thin provisioning disk volume under the specified directory path.
A system of operating block-based thin provisioning disk volumes, the system comprising:
- a first storage system;
- a second storage system;
- and
- a network connecting the first storage system and the second storage system;
- wherein, in response to a volume creation request to create a thin provisioning disk volume in the first storage system, the first storage system records attribute information of the block-based thin provisioning disk volume in the first storage system;
- wherein the first storage system specifies a directory path for the block-based thin provisioning disk volume in a file system in the second storage system;
- and
- wherein the first storage system creates a directory for the block-based thin provisioning disk volume under the specified directory path.
A computer-readable storage medium storing a plurality of instructions for controlling a data processor to operate 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 plurality of instructions comprising:
- instructions that cause the data processor, in response to a volume creation request to create a thin provisioning disk volume in the first storage system, to record in the first storage system attribute information of the block-based thin provisioning disk volume;
- instructions that cause the data processor to specify a directory path for the block-based thin provisioning disk volume in a file system in the second storage system;
- and
- instructions that cause the data processor to create a directory for the block-based thin provisioning disk volume under the specified directory path.
