Another independent realworld test, with scripts so you could repeat
it yourself - http://vizzzion.org/?id=reiser4-2

In my experience, ext2/3 still seem to be rock solid in terms of
stability, resiliance, and ability to recover from corruption. I've
heard many horror stories of Reiser filesystems vanishing, and seen
XFS filesystems zero out files. The XFS kernel code I've also seen
panic machines (I don't believe a corrupt filesystem should panic a
machine).

I've also observed odd things happen with JFS's kernel threads once
or twice in several months, but otherwise if found it to be quite a
stable filesystem (no quota or ACL support though).

My 2c,

Bernard.
