Chapter 1: HP Clustered File System Commands 37

When you have completed your work with the suspended filesystem, use

the psfsresume utility to resume the filesystem. Issue the psfsresume

command from the server where you executed psfssuspend. You must be

user root.

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 partition, such as /dev/psd/psd1p7, that

contains the copied filesystem, and <label> is the name that should

be used to identify the filesystem.

/opt/hpcfs/tools/psfslabel <device> “<label>”

psfssema – manage cluster-wide file locks

Synopsis

/opt/hpcfs/bin/psfssema -i <filename>

/opt/hpcfs/bin/psfssema -g <filename>

/opt/hpcfs/bin/psfssema -r <filename>

/opt/hpcfs/bin/psfssema -d <filename>

Description

The psfssema semaphore utility provides a simple synchronization

mechanism for managing cluster-wide file locks. This utility can be used

in shell scripts on different nodes of a cluster and takes advantage of the

PSFS filesystem and its internode communication abilities. For example,

you might want to use cluster-wide file locking in a Start or Stop script for

a service or device monitor.

The options are:

-i <filename>

Create the PSFS command-line semaphore file <filename> and the

supplemental file <filename.pid> if either file does not already exist. It

then initializes the files to create the PSFS command-line semaphore.

<filename> must be a path on a PSFS filesystem.

-g <filename>

Lock the PSFS command-line semaphore associated with <filename>,

which is the name of a semaphore file created by psfssema -i.
