Before starting GPFS™, you must build and install the GPFS portability layer.
The GPFS portability layer is a loadable kernel module that allows the GPFS daemon to interact with the operating system.
Note: The GPFS kernel module should be updated
any time the Linux kernel is
updated. Updating the GPFS kernel
module after a Linux kernel
update requires rebuilding and installing a new version of the module.
To
build the GPFS portability layer
on Linux nodes, do the following:
- Check for the following before building the portability layer:
- Updates to the portability layer at the IBM® Support Portal: Downloads for General Parallel File System.
- The latest kernel levels supported in the GPFS FAQ in IBM Knowledge Center.
- Build your GPFS portability
layer in one of the following ways:
Using the mmbuildgpl command
(recommended). See the GPFS:
Administration and Programming Reference for more
information.
- Using the Autoconfig tool.
- Using the directions in /usr/lpp/mmfs/src/README.
