Abstract
A technique for repairing damage to a file system stores compression headers in association with respective extents of in-line compressed data. A repair utility reads contents from the compression headers and applies the contents to repair damaged metadata structures that the file system uses to access the associated extents. In this fashion, the repair utility restores access to compressed data, which would otherwise be lost.
