Abstract
Example apparatus and methods concern identifying an error in a file system. The error is identified during one or more b-tree traversals through the file system. A fix for the error is produced upon detecting the error. Data or metadata associated with the fix is not initially written to the file system, but instead is stored somewhere other than the file system using a copy on write approach. After the traversals are complete, the file system may be fixed using the data or metadata stored using the copy on write approach.
