Certain operations on a dynamic volume cause a warning

On Windows Server operating systems, operations on a dynamic volume (such as change drive letter, delete, or shrink) result in a warning message stating that the volume is currently in use. This is a known Microsoft volume lock problem (SRX080317601931) (1093454).

Workaround: If no applications are utilizing the volume, complete the operation by responding to the warning message to perform the operation with force.
