Installing GFS
While you can follow the instructions provided by http://www.redhat.com/docs/en-US/
Red_Hat_Enterprise_Linux/5.2/html/Cluster_Administration/index.html to configure and
manage GFS, this section provides only the steps needed. (http://www.redhat.com/docs/en-US/
Red_Hat_Enterprise_Linux/5.2/html/Global_File_System/index.html describes GFS and how
to install a broader range of tools.) Also, these steps assume that the physical cabling of the
servers and storage is complete and connectivity has been verified.
To install GFS
1. Log in to the operating system of the VTS server.
2. Become root:
su -
3. Mount the GFS Install/Upgrade DVD. This example illustrates mounting the DVD on
/media/cdrom:
mkdir -p /media/cdrom
mount /dev/cdrom /media/cdrom
4. Install the GFS RPMs by entering the following command:
/media/cdrom/vts-6.04-gfs-install/installGFS.bash
Ignore any warnings that may be displayed.
5. Unmount and eject the DVD:
umount /media/cdrom
eject
6. Enter the following commands to disable clustering services that are included with the
GFS but not used by VTS. Failure to disable these can cause the system to hang.
chkconfig openais off && service openais stop
chkconfig saslauthd off && service saslauthd stop
If any of these commands returns a failure, it is not an error. It indicates that the process
was not running.
