Systems and methods for mitigating write-back caching failures

摘要

A computer-implemented method for mitigating write-back caching failures may include (1) detecting a failure that impairs at least one write-back cache that temporarily caches updates for individual files stored on a storage device, (2) identifying an attribute of an individual file stored on the storage device in response to the failure that impairs the write-back cache, (3) determining that at least a portion of the individual file is obsolete based at least in part on the attribute of the individual file, and then (4) performing at least one mitigating action with respect to the individual file to address the obsolete portion of the individual file. Various other methods, systems, and computer-readable media are also disclosed.

1. A computer-implemented method for mitigating write-back caching failures, at least a portion of the method being performed by a computing device comprising at least one processor, the method comprising:
detecting a failure that impairs at least one write-back cache that temporarily caches updates for individual files stored on a storage device; in response to detecting the failure that impairs the write-back cache:
identifying, at the storage device, an attribute of an individual file stored on the storage device;determining, based at least in part on the attribute of the individual file stored on the storage device, that at least a portion of the individual file stored on the storage device is obsolete; in response to determining that the portion of the individual file stored on the storage device is obsolete, performing at least one mitigating action with respect to the individual file stored on the storage device by updating the individual file based at least in part on an update that is flushed to the storage device to address the obsolete portion of the individual file.
