Abstract
In general, the invention relates to a method for managing data. The method includes detecting a fault domain failure in a fault domain of a plurality of fault domains, and in response to the detecting, initiating a rebuilding of data in a spare fault domain of using checkpoint metadata and slice metadata, wherein the data is a copy of data that was stored in the fault domain and wherein the spare fault domain is not one of the plurality of fault domains.
Claims20
A method for managing data, the method comprising:
- detecting a fault domain failure in a fault domain of a plurality of fault domains;
- and
- in response to the detecting, initiating a rebuilding of data in a spare fault domain using checkpoint metadata and slice metadata, wherein the data is a copy of data that was stored in the fault domain and wherein the spare fault domain is not one of the plurality of fault domains.
A system, comprising:
- a processor;
- a data processor, which when executed by the processor performs a method, the method comprising:
- detecting a fault domain failure in a fault domain of a plurality of fault domains;
- and
- in response to the detecting, initiating a rebuilding of data in a spare fault domain using checkpoint metadata and slice metadata, wherein the data is a copy of data that was stored in the fault domain and wherein the spare fault domain is not one of the plurality of fault domains.
A non-transitory computer readable medium comprising computer readable program code, which when executed by a computer processor enables the computer processor to perform a method, the method comprising:
- detecting a fault domain failure in a fault domain of a plurality of fault domains;
- and
- in response to the detecting, initiating a rebuilding of data in a spare fault domain using checkpoint metadata and slice metadata, wherein the data is a copy of data that was stored in the fault domain and wherein the spare fault domain is not one of the plurality of fault domains.
