HSM file system filter problems

Description			All ordinary file system operations can be performed on an HSM file system that is currently
			operating in Limited Access Mode. No file or directory creation, move, deletion, rename, and
			similar operations are prevented.
			(Windows system specific)
Explanation			Most probably the HSM file system filter cannot attach to the HSM file system, because the
			system native NTFS has already attached itself. A possible reason may be that you forgot to
			dismount NTFS from the disk volume that stores the HSM file system.
Workaround			To detach NTFS from the problematic disk volume, enter:
			fse --dismount-ntfs VolumeName
			The HSM file system filter will attach itself to the disk volume when the HSM file system is
			accessed for the first time.

			NOTE: The FSE implementation does not know about the files that were created while the


			HSM file system filter was not attached to the HSM file system. To expose these files to the FSE
			implementation, follow the procedure described in ”HSM file system access modes” on
			page 148.

Description	Formatting an FSE partition fails.
	(Windows system specific)
Explanation	Formatting may fail if FSE is not running on the consolidated FSE system or external FSE client.
	The file system filter, which intercepts and can block actions for file systems, recognizes the
	stopped FSE implementation. In such a case, formatting a file system will most likely fail.
Workaround	Before formatting the FSE partition, mount it as described in the workaround for problem After
	formatting an FSE partition, the FSE partition is not mounted and HSM does not start in section
	”HSM file system mounting problems ” on page 255.

Description	Running Disk Defragmenter on a HSM file system triggers the so-called blue screen of death
	(BSOD).
	(Windows 2000 Server specific)
Explanation	Defragmenting HSM file systems is not supported as the defragmentation of an HSM file system
	causes corruption and data loss. HSM file system filter triggers BSOD in order to prevent the
	defragmentation process from actually starting the defragmentation of the HSM file system.
Workaround	None
