Abstract
A storage controller maintains extent space efficient storage volumes in a primary allocation space and a secondary allocation space. An indicator is used to indicate that extents of the secondary allocation space are available for an extent pool, without releasing the extents from the secondary allocation space.
Claims15
A method, comprising:
- maintaining, by a storage controller, extent space efficient storage volumes in a primary allocation space and a secondary allocation space;
- allocating the secondary allocation space to an application, in response to the primary allocation space being full;
- and
- writing data to the secondary allocation space subsequent to the secondary allocation space being allocated, and the primary allocation space being full.
1 more element
A system, comprising:
- a memory;
- and
- a processor coupled to the memory, wherein the processor performs operations, the operations comprising:
- maintaining, by a storage controller, extent space efficient storage volumes in a primary allocation space and a secondary allocation space;
- allocating the secondary allocation space to an application, in response to the primary allocation space being full;
- and
- writing data to the secondary allocation space subsequent to the secondary allocation space being allocated, and the primary allocation space being full.
4 more elements
A computer program product, the computer program product comprising:
- a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code configured to perform operations on a processor, the operations comprising:
- maintaining, by a storage controller, extent space efficient storage volumes in a primary allocation space and a secondary allocation space;
- allocating the secondary allocation space to an application, in response to the primary allocation space being full;
- and
- writing data to the secondary allocation space subsequent to the secondary allocation space being allocated, and the primary allocation space being full.
