Abstract
This document describes tools capable of enabling an entity requiring exclusive access to data and metadata of a volume to have that exclusive access while also permitting another entity to have access to data and metadata of that volume. The tools, for example, may permit a ChkDsk program to detect and correct data/metadata integrity errors while permitting users to maintain access to a live volume having that data and metadata. In one embodiment the tools create a copy of a logical volume, permit exclusive access to the copy while permitting access to the live volume, and, when the exclusive access is no longer needed, merge the copy and the live volume.
