Abstract
Perceived corruptions encountered on file system volumes, and which cannot be initially remedied online, are processed to verify whether they are true, existing volume data structure corruptions or, alternatively, false positives. Upon the verification of one or more of a volume's corruptions, error scanning is performed to check for, and attempt to remedy online, all the existing corruptions on the volume. Subsequent to error scanning processing, if one or more verified corruptions continue to exist on a file system volume, at file system boot up time spot corruption correction is performed to attempt to remedy the existing, verified corruptions on the volume. Spot corruption correction is performed to attempt to correct verified data structure corruptions on a volume of the file system while the volume is maintained offline for the time necessary to attempt to correct its prior identified corruptions.
