File system resiliency management

A computing device for resilient file system management, the computing device comprising:

• a storage device having a volume stored thereon, wherein the volume comprises at least one data structure;
• a memory adapted to store instructions;
• and
• a processor adapted to execute the instructions, the instructions being organized into at least:
• a file system manager to manage the file system;
• a spot corruption verifier to:
• determine if a perceived corruption that has been previously encountered on the volume of the file system is a true data structure corruption comprising a confirmed corruption, and
• determine if the perceived corruption that has been previously encountered on the volume of the file system is a false positive comprising an encounter on the volume of the file system that is not the true data structure corruption on the volume of the file system;
• a proactive error scanner to identify data structure corruption on the volume of the file system, wherein data structure corruptions identified by the proactive error scanner that are not remedied during proactive error scanner processing comprise confirmed corruptions;
• and
• a spot corruption corrector to attempt to correct the confirmed corruptions.

A method for file system error detection and correction for a file system that comprises at least one volume comprising at least one data structure, the method comprising:

• generating verification indications for multiple perceived corruptions on the at least one volume of the file system;
• performing spot corruption verification processing for the at least one volume of the file system that has the multiple perceived corruptions for which verification indications have been generated, wherein the spot corruption verification processing comprises determining that at least one of the multiple perceived corruptions that comprise true data structure corruption to be a confirmed corruption, wherein the spot corruption verification processing further comprises determining that at least another of the multiple perceived corruptions that do not comprise true data structure corruption to be a false positive, and wherein the spot corruption verification processing is performed while the volume of the file system is maintained online;
• performing proactive error scan processing for the volume of the file system, wherein the proactive error scan processing comprises checking the volume of the file system that has the confirmed corruption to identify additional corruptions thereon, and attempting to remedy the confirmed corruption and the additional corruptions while the volume of the file system is maintained online, and wherein each of the additional corruptions that is not remedied while the volume of the file system is maintained online comprises an existing corruption;
• and
• performing spot corruption correction processing for the volume of the file system that has at least one existing corruption, wherein the spot correction processing for the volume of the file system comprises an attempt to correct each of the existing corruptions on the volume of the file system while the volume of the file system is maintained offline.
