3.4.0 Matrix Server Release Notes

PolyServe Matrix Server Release Notes 8

traverse access checking to protect sensitive data that is encoded in the

names of files or directories. Instead, the user should place sensitive

data in files and should rely on file security descriptors to deny access

to the filesʹ contents by unauthorized users.

Windows Utilities and Services

The following Windows utilities differ in operation on NTFS and PSFS

filesystems:

• Disk checks. In both Windows Explorer and the Disk Management

utility, you can right-click a disk volume to see its properties. The

Tools tab on the Properties window includes an option to check the

disk volume for errors. This option cannot be used with PSFS

filesystems. Also, the command-line chkdsk utility cannot be used to

check for errors. In place of these utilities, use the Matrix Server

psfscheck utility to check the disk. See the PolyServe Matrix Server

Administration Guide for details about the utility.

• Remote Storage Service. The Remote Storage Service might not

operate correctly. If the matrix has a large number of disks, you may

see error messages generated from this service. If you do not need the

Remote Storage Service, it can be disabled in the Services Control

Panel applet.

Windows Applications

You may notice the following differences from NTFS filesystems when

running applications on PSFS filesystems:

• Certain Windows applications will disable NTFS-related features

when run on a PSFS filesystem. For example, older versions of

Robocopy will not copy security descriptors. (As a workaround, use

Xcopy to copy the security descriptors.)

Open Issues and Workarounds

The following open issues affect PolyServe Matrix Server, the Matrix

Database Solution Pack for SQL Server, and the Matrix File Serving
