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 132.
Description Formatting an FSE partition fails (Windows system-specific).
Explanation Formatting may fail if FSE is not running on the consolidated FSE implementation or the 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 Mount the FSE partition as described in the 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 the previous section.
Description Running Disk Defragmenter on a HSM file system triggers a blue screen (Windows FSE
client-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 a blue screen in order to prevent
the defragmentation process from actually starting the defragmentation of the HSM file system.
