3.5.1 Matrix Server Administration Guide

Chapter 9: Manage Filesystem Quotas 186

NOTE: You do not need to install this RPM to use quotas with PSFS

filesystems. With the exception of warnquota, all of the

functionality of these commands is provided by the Quotas

window on the Management Console and by the mx quota

commands.

Be sure to invoke the Matrix Server versions of these commands instead

of the versions provided with the Linux distribution. (Either add

/opt/polyserve/bin and /opt/polyserve/sbin to the beginning of your path, or

invoke the commands by their complete pathnames.)

The commands can be used with both PSFS filesystems and the standard

Linux filesystem types. There are no changes to the syntax or operation of

the commands. See the man pages provided with your Linux

distribution’s “quota” or “quota-tools” RPM for details about using the

commands.

Back Up and Restore Quotas

The psfsdq and psfsrq commands can be used to back up and restore the

quota information stored on the PSFS filesystem. These commands

should be run in conjunction with standard filesystem backup utilities, as

those utilities do not save the quota limits set on the filesystem.

psfsdq Command

This command saves a quota summary for all users and groups having

quota information stored on the specified PSFS filesystem. The command

has this syntax:

/opt/polyserve/sbin/psfsdq [-f <path>] <filesystem>

The -f option specifies the file to which psfsdq will write its output. If the

file already exists, it will be overwritten. If -f is not specified, psfsdq

writes to stdout. filesystem is the psd or psv device used for the filesystem.

psfsrq Command

This command restores the quota data generated by the psfsdq command

to the specified PSFS filesystem. The command has this syntax:

/opt/polyserve/sbin/psfsrq [-f <path>] <filesystem>
