What is CentOS-3?
CentOS is an Enterprise-class Linux
Distribution derived from sources freely provided to the public by a
prominent North American Enterprise Linux vendor. CentOS conforms fully
with the upstream vendors redistribution policy and aims to be 100% binary
compatible. (CentOS mainly changes packages to remove upstream vendor
branding and artwork.) CentOS is free. For more information please
visit the web site.
What is CS?
The Cluster Suite or CS is a of
technologies working together to provide data integrity and the ability to
maintain application availability in the event of a failure.
Administrators can deploy enterprise cluster solutions using a combination
of hardware redundancy along with the failover and load-balancing
technologies. It is not requires by GFS but may be used in
conjunction.
What is GFS?
The Global File System or GFS is a
cluster file system with full POSIX semantics. It is designed for
shared storage systems but can also be used by exporting existing storage
over the network. For more information visit
RedHat or the
project home page.
Obtaining CS & GFS
CS and GFS are mirrored on the CentOS mirrors
together in one directory csgfs. You can download from
http://mirror.centos.org/centos/3/csgfs/i386/ or you local mirror. If you use yum you
can add this to your /etc/yum.conf
[csgfs]
name=CentOS-3 CS and GFS
baseurl=http://mirror.centos.org/centos/3/csgfs/i386/
The packages are now signed with the
CentOS-3 gpg key.
Installing CS & GFS
Follow the vendor instructions.
Original Announcement
Announcing CentOS 3 i386
Cluster Suite (CS) and Global File System (GFS)
CentOS csgfs is now available for CentOS-3 i386. This is a built from
source found here:
ftp://ftp.redhat.com/pub/redhat/linux/enterprise/3/en/RHCS/i386/SRPMS/
ftp://ftp.redhat.com/pub/redhat/linux/enterprise/3/en/RHGFS/i386/SRPMS/
ftp://ftp.redhat.com/pub/redhat/linux/updates/enterprise/3AS/en/RHCS/SRPMS/
ftp://ftp.redhat.com/pub/redhat/linux/updates/enterprise/3AS/en/RHGFS/SRPMS/
CentOS-3 csgfs combines both the Cluster Suite 3 (CS) and the Global File
System 6.0 (GFS) into a single directory (csgfs). This makes it convenient
if you use both but you can still use just the CS or the GFS on their own as
you require.
The manual for these products can be found in the rh-cs-en-3-2.noarch.rpm
and rh-gfs-en-6.0-4.noarch.rpm packages.
The following web sites relate to this software:

Please remember that CentOS provides community support via the
centos@centos.org mailing list, forums and irc.
If you need payed up support then CentOS csgfs is probably not for you.
You do not need extra hardware to use this software. Without hardware like
shared storage and fencing equipment you may not receive all the benefits
that this software can deliver.
Updates to this software often lag significantly behind the core CentOS
updates. For this reason you should take appropriate measures to protect
the security of your servers which are using CentOS csgfs.
You can find CentOS csgfs under the centos/3/csgfs/i386/ directory of your
favorite CentOS mirror. Yum headers are provided so you can easily
integrate with the standard CentOS package management tools.
Depending on your fencing method, you may require an extra perl module
perl-Net-SSLeay. This can be obtained from Dag/RpmForge.
Enjoy.
