Abstract

There is disclosed a computer-implemented method, an apparatus, and a computer program product for use in storage object recovery. In one embodiment, the method comprises determining that a storage object requires recovery, wherein the storage object comprises a dedicated recovery area at a fixed location. The method further comprises taking offline the storage object in response to determining that the storage object requires recovery. The method still further comprises performing a recovery procedure to recover the storage object, the recovery procedure utilizing the dedicated recovery area to support storage object recovery.

Claims (20)

1. A computer-implemented method, comprising:

allocating a scratch space to support recovery of a storage pool, wherein the storage pool comprises a set of allocatable slices and the scratch space is distinct with respect to the set of allocatable slices such that a slice allocator for allocating slices from the storage pool is unware of the existence of the scratch space;

after at least a portion of the set of slices have been allocated, taking offline the storage pool for facilitating recovery of the storage pool; and

while the storage pool is offline, performing a storage pool recovery procedure to recover the storage pool, the storage pool recovery procedure utilizing the scratch space that was allocated to support the storage pool recovery.

2. The method as claimed in claim 1 , further comprising:

moving the storage pool online upon completion of the recovery procedure.

3. An apparatus, comprising:

at least one processing device, said at least one processing device comprising a processor coupled to a memory:

wherein the apparatus is configured to:

allocate a scratch space to support recovery of a storage pool, wherein the storage pool comprises a set of allocatable slices and the scratch space is distinct with respect to the set of allocatable slices such that a slice allocator for allocating slices from the storage pool is unware of the existence of the scratch space;

after at least a portion of the set of slices have been allocated, take offline the storage pool for facilitating recovery of the storage pool; and

while the storage pool is offline, perform a storage pool recovery procedure to recover the storage pool, the storage pool recovery procedure utilizing the scratch space that was allocated to support the storage pool recovery.

4. The apparatus as claimed in claim 3 , wherein the apparatus is further configured to:

move the storage pool online upon completion of the recovery procedure.

5. A computer program product having a non-transitory computer-readable medium storing instructions, the instructions, when carried out by one or more processors, causing the one or more processors to perform a method of:

allocating a scratch space to support recovery of a storage pool, wherein the storage pool comprises a set of allocatable slices and the scratch space is distinct with respect to the set of allocatable slices such that a slice allocator for allocating slices from the storage pool is unware of the existence of the scratch space;

after at least a portion of the set of slices have been allocated, taking offline the storage pool for facilitating recovery of the storage pool; and

while the storage pool is offline, performing a storage pool recovery procedure to recover the storage pool, the storage pool recovery procedure utilizing the scratch space that was allocated to support the storage pool recovery.

6. The computer program product as claimed in claim 5 , the computer program product further stores instructions, the instructions, when carried out by one or more processors, causing the one or more processors to further perform a method of:

moving the storage pool online upon completion of the recovery procedure.
