Arun Singh shows us how to create shared storage on SUSE Linux Enterprise Server 10 using OCFS2 (Oracle Cluster File System v2 for shared storage) and Xen Virtualization technology. Enterprise grade shared storage can cost you lots of money but here no real expensive shared storage used. The information provided here works with real shared storage as well:

This paper is to help you to understand the steps involved in creating shared storage without using expensive shared storage. Using this information you can create shared storage used by all xen guest OS and Host, avoiding copying of files between guest OS’s. Hope you will find this paper useful.

You can easily port instructions to Redhat or any other Linux distro without a problem. You can also use Redhat’s Global File System (GFS) too. We often use Fibre Channel or iSCSI, devices for GFS shared storage.
