3.1.2 Matrix Server Administration Guide

Chapter 7: Configure PSFS Filesystems 101

The --persist argument causes the filesystem to be mounted

automatically whenever the server is rebooted. The --activate argument

mounts the filesystem now. The --path argument specifies the directory

mountpoint. See the Matrix Server Command Reference for a description of

the options.

The Linux mount Command

Use the following syntax to mount a filesystem. The directory

mountpoint must already exist.

mount -t psfs -o options device mountpoint

The device can be either a psd or psv device. Use this syntax to specify the

device:

• For a psd device partition, the device is specified as

/dev/psd/psdXXXpYY, where XXX is the drive number and YY is the

partition number. For example, /dev/psd/psd6p4 specifies partition 4

on disk psd6.

• For a non-partitioned psd device, the device is specified as

/dev/psd/psdXXX, where XXX is the drive number. For example,

/dev/psd/psd5.

• 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 “Persistent Mounts” on page 103.)
