"This tutorial will show you how to install and use JFS
under Linux. JFS is an enterprise journalling filesystem
technology currently used by IBM enterprise servers and now being
ported to Linux. This tutorial assumes that you have some
experience compiling your own Linux kernel. If not, please
take the Compiling the Linux kernel tutorial on developerWorks, and
then head back here."
"JFS is an advanced journalling filesystem. It has been designed
to provide excellent performance and high availability for server
environments. However, JFS is also well suited for Linux
workstations and home machines, since everyone can benefit from a
reliable filesystem with high performance."
