Abstract
A technique for correcting errors in a data storage system operates while the data storage system remains online. The technique includes identifying an object for validation, scanning a plurality of pointers, and counting a number of pointers that point to the object. The technique further includes repairing a discrepancy between the count of pointers and a reference count stored in connection with the object.
