or if you are using Red Hat Linux Version 2.1.

2. Install the GFS RPM.

3. Load the GFS kernel modules.

Note

This step is required only if you are using Red Hat Enterprise Linux Version 3, Update 1 or earlier, or

if you are using Red Hat Linux Version 2.1.

Installing a Linux kernel consists of downloading and installing a binary kernel built with GFS patches

applied and, optionally, compiling third-party drivers not included with the kernel (for example, HBA

drivers) against that kernel. The GFS kernels have been built by applying GFS patches against vendor
