Preventing unnecessary data recovery

摘要

A method that prevents unnecessary data recovery includes receiving, at a data processing device, a status of a resource of a distributed system. When the status of the resource indicates a resource failure, the method includes executing instructions on the data processing device to determine whether the resource failure is correlated to any other resource failures within the distributed system. When the resource failure is correlated to other resource failures within the distributed system, the method includes delaying execution on the data processing device of a remedial action associated with the resource. However, when the resource failure is uncorrelated to other resource failures within the distributed system, the method includes initiating execution on the data processing device of the remedial action associated with the resource.

1. A method comprising:
receiving, at a data processing device, a status of a resource of a distributed system; when the status of the resource indicates a resource failure, executing instructions on the data processing device to determine whether the resource failure is correlated to any other resource failures within the distributed system; when the resource failure is correlated to other resource failures within the distributed system, delaying execution on the data processing device of a remedial action associated with the resource; when the resource failure is uncorrelated to other resource failures within the distributed system, initiating execution on the data processing device of the remedial action associated with the resource; when the resource failure is correlated to other resource failures within the distributed system, executing the remedial action on the data processing device after a first threshold period of time; and when the resource failure is uncorrelated to other resource failures within the distributed system, executing the remedial action on the data processing device after a second threshold period of time; wherein the first threshold period of time is greater than the second threshold period of time.
