ext3 and ext2 are nearly identical except for the journal file. If you are installing
openSUSE Linux over an existing ext2 file system, you might want to use ext3 instead of
ReiserFS. The chief advantage of the ext3 file system is that it will automatically recognize
files on ext2, and reformatting is not required.
JFS and XFS
IBM??™s original Journaling File System (JFS) and the XFS file system from SGI (formerly
Silicon Graphics, Inc.) are file systems that were designed for other Unix versions now
ported to Linux. JFS was the file system of choice for AIX users. SGI created XFS to be the
basis for its IRIX systems.
JFS introduced journaling to Linux and has its own version of fsck to handle problem
boots. XFS claims superior performance than either JFS or ReiserFS. Perhaps one of these
will work for you.

Choosing a File System
Don??™t fret endlessly over what file system to choose. All the file systems discussed here are
excellent. It is a one-time decision, though. There is some pain involved with changing
file systems after installation, especially when moving from ext2 or ext3 to ReiserFS.
