Faulty component isolation in storage systems

A storage system, comprising:

• multiple modules configured at a first time to store and process storage requests for respective sets of data objects, each of the modules configured:
• to identify, while processing the storage requests, respective subsets of the data objects having one or more data errors,
• to identify, at a second time subsequent to the first time, respective modules storing each of the data objects having at least one data error,
• to compute, based on the identified modules, a frequency distribution of the identified data errors in the data objects over the multiple modules,
• to identify, based on the frequency distribution, a failure in a given module, and
• to remove the identified module from the storage system.

A computer program product, the computer program product comprising:

• a non-transitory computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising:
• computer readable program code configured to arrange, at a first time, a storage system comprising multiple modules to store and process storage requests for respective sets of data objects;
• computer readable program code configured to identify, while processing the storage requests, respective subsets of the data objects having one or more data errors;
• computer readable program code configured to identify, at a second time subsequent to the first time, respective modules storing each of the data objects having at least one data error;
• computer readable program code configured to compute, based on the identified modules, a frequency distribution of the identified data errors in the data objects over the multiple modules;
• computer readable program code configured to identify, based on the frequency distribution, a failure in a given module;
• and
• computer readable program code configured to remove the identified module from the storage system.
