Abstract

A system and method for performing File System checKing (FSCK) allows a file system to be accessed while the file system is being checked for consistency in the background. In the event that a file is accessed prior to having been checked for consistency by the background FSCK process, the background FSCK process is interrupted, and an in-context FSCK is performed on the accessed file. In addition, an in-context FSCK method and system is described which uses a snapshot block bitmap, FSCK block bitmap and FS block bitmap to check block consistency in the context of handling a block access to handle consistency and corruption issues as part of the file access.
