Shalom,

Red Hat 4.6 has a full cluster suite, it has to be licensed, though red hat calls it support.

You can also use Centos http://www.centos.org and get it all for free without support.

To install you download the rpms and install them all at the same time. rpm -ivh *.rpm

You can use the yum groupinstall clustering command if you go the CentOS route.

GFS is designed to permit simultaneous write access from more than one machine to the same file. You need to make sure any applications like databases are configured to handle that.

Regular Oracle server will either not permit this kind of access or corrupt your data.

Oracle RAC is certified in this environment.

if you just need the cluster VG for fail over and not for accessing(mounted) the data from multiple nodes at the same time then you can avoid GFS. You can just fail over the cluster service(including the FS from cluster aware VG ) to alternate node. That is what we use but with RNEL 5.1 and not much satisfied though...
