3.6.0 Matrix Server 3.6.0 Administration Guide (5697-7081, December 2007)

Chapter 9: Configure PSFS Filesystems 99

• You do not have to assign the same mount points or drive letters to

each filesystem on each node. When you use the PolyServe

Management Console to assign a drive letter/mount point, the

assignment applies to every node. However, you can use the mx fs

assign command or the Windows LDM, mountvol.exe, or

diskpart.exe commands to assign drive letters/mount points uniquely

on each node.

• You can assign multiple mount points to the same filesystem if

necessary.

• Permissions can be locked down to prevent users from accessing the

reserved mount points in the conf directory. You can use Windows

Explorer or other tools to change permissions on the conf\mounts

directory or on individual mount points. (Be careful not to change

permissions for the root of the mounted filesystem.) Also, do not

remove LocalSystem or Administrators from the permissions, as

doing this could cause operating system or Matrix Server problems.

• You do not have to share the same filesystems on each node via CIFS.

Create a Filesystem

A PSFS filesystem can be created on a basic volume (a psd device) or a

dynamic volume (a psv device). You can create a filesystem from one

server in the matrix using either the PolyServe Management Console or

the command line.

NOTE: The minimum size for a PSFS filesystem is 64 MB.

Before creating a filesystem, verify the following:

• The disk is partitioned appropriately. If you want to change the

partition layout, you will need to deport the disk, modify the partition

layout with the Windows Disk Management utility, and then reimport

the disk.

• The volume to be used for the filesystem does not contain needed

data. The new filesystem will write over an existing filesystem

currently on the volume.
