3.5.1 Matrix Server Administration Guide

Chapter 7: Configure PSFS Filesystems 124

NOTE: If an attempt to mount the copied filesystem fails with an “FSID

conflict” error, run the following command as user root. In the

command, <device> is the psd or psv device, such as

/dev/psd/psd1p7 or /dev/psv/psv1, containing the copied

filesystem, and <label> is the name that should be used to identify

the filesystem.

# /opt/polyserve/tools/psfslabel <device> “<label>”

Resize a Filesystem Manually

The resizepsfs utility can be used to increase the size of a PSFS filesystem.

(Reducing the size of a PSFS filesystem is not supported.) resizepsfs can

grow a filesystem online if the filesystem is mounted on the server where

the utility is invoked. Otherwise, the filesystem must be unmounted on

all servers before it is resized.

The utility has this syntax:

# /opt/polyserve/sbin/resizepsfs -s [+]size[K|M|G|T] [-q]

The utility can be used with either psd or psv devices. 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.

This program does not change the size of the partition containing the

filesystem. Instead, you will need to use a utility specific to your RAID

subsystem to modify the size of the partition. You will need to deport the

disk containing the filesystem before you modify the partitions.

CAUTION: Be sure to back up your data before using this program.
