Now, on to filesystem types. Right now, you have four filesystem
options: XFS, ext2, ext3 (journaling) and ReiserFS. ext2 is the tried
and true Linux filesystem but doesn't have metadata journaling. ext3 is
the new version of ext2 with both metadata journaling and ordered data
writes, effectively providing data journaling as well. ReiserFS is a
B*-tree based filesystem that has very good small file performance, and
greatly outperforms both ext2 and ext3 when dealing with small files
(files less than 4k), often by a factor of 10x-15x. ReiserFS also scales
extremely well and has metadata journaling. As of kernel 2.4.18+,
ReiserFS is finally rock-solid and highly recommended. XFS is a
filesystem with metadata journaling that is fully supported under
Linux's xfs-sources kernel, but be warned that it is highly unstable at
this time.
If you're looking for the most standard filesystem, use ext2. If you're
looking for the most rugged journalled filesystem, use ext3. If you're
looking for a high-performance filesystem with journaling support, use
ReiserFS; both ext3 and ReiserFS are mature and refined. Please be
careful with XFS; this filesystem has a tendency to fry lots of data if
the system crashes or you lose power.
