Windows-specific recommendations

Improving performance of the FSE-Samba integration

You can improve performance of clients running on Windows 2000 systems using Samba shares on the HSM file systems by modifying the timing parameters of the Workstation Service (formerly LAN Manager), depending on the particular environment load and usage policy. These parameters are described in Microsoft Knowledge Base articles Q102981 and Q102067.

The articles mention default values for particular registry keys that affect Samba communication. For more details, see the web sites:

NOTE: Modifying the values of timing parameters can increase or decrease the Samba performance. Be especially cautious when setting the value for the redirector session time-out parameter (SessTimeout).

Enabling early migration of the data located on a former NTFS volume

After a non-empty NTFS disk volume is assigned to a newly configured FSE partition, the volume is mounted using the HSM file system in Full Access Mode. Existing directories and files are added to the HSM migration candidate list when they are accessed for the first time. There may be a long delay before a particular directory or file is actually migrated.

To speed up the migration process, you are advised to run a tree walk on such an HSM file system. The tree walk process must be performed by a third-party application or tool, not by an FSE command.

The following is an example of a tool that you can use for this purpose. The dir command scans through the whole HSM file system hierarchy of the disk volume and puts each object on the migration candidate list. Before invoking this command, change the current directory to the mount point of the HSM file system:

VolumeMountPoint\>dir /S
