You have a computer that is running Windows Server 2008 or Windows Vista. When you unmount a volume, delete a snapshot or try to fail over a disk on which snapshots are saved to another Cluster node, you receive the following Stop error message:
The four parameters in this error message vary, depending on the computer's configuration.
Not all "0x000000D6" Stop errors are caused by this problem.
This issue occurs because of a timing issue in the mount manager. The mount manager releases a lock and then requires the same lock when it enumerates all volumes. However, the mount manager does not check whether any volume change occured when it obtains the lock again. The timing issue occurs if any volumes or snapshots become unavailable in this period. Therefore, the mount manager accesses an invalid object. This behavior causes the stop code error.
