3.5.1 Matrix Server Administration Guide

Chapter 7: Configure PSFS Filesystems 112

• For a psv device, the device is specified as /dev/psv/psvXXX, where

XXX is the volume number. For example, /dev/psv/psv1.

For example, the following command mounts the filesystem on the

partition /dev/psd/psd12p6 in read-write mode at the mountpoint /data1.

mount -t psfs -o rw /dev/psd/psd12p6 /data1

If you are mounting a filesystem with quotas, you will need to include the

following options to enable the user and/or group quota functionality of

the Linux quota commands:

• For user quotas, specify either -o usrquota or -o quota.

• For group quotas, specify -o grpquota.

The following mount options are not supported:

•The -o atime option. Instead, use the PSFS filesystem atime update

feature. (See “Configure atime Updates” on page 121.)

•Use of the remount option to change the way a filesystem is mounted.

For example, you cannot use mount -o remount,rw to remount a

filesystem as read-write if it was originally mounted read-only.

The mount operation ignores any options that are not supported by the

PSFS filesystem. See mount_psfs(8) for more information.

Unmount a Filesystem

You can unmount a PSFS filesystem from either the Management Console

or the command line.

Unmount from the Management Console

The Management Console provides two ways to unmount a filesystem:

• To unmount a filesystem on one server, select the “

Mounted” entry for

that server on the Filesystems window, right-click, and select

Unmount. The filesystem will then be unmounted.

• To unmount a filesystem on more than one server, select the filesystem

on the Filesystems window, right-click, and select Unmount. When

the Unmount Filesystem window appears, select the servers where

the filesystem is to be unmounted.
