Right, and since XFS is meta-data journalling (like reiser), you have no more protection of data integrity than with reiserfs. I have reiser on my laptop, and xfs on my desktop machine. As you can image, the laptop loses power far more often than the desktop machine does, yet I haven't been able to find a situation where I've been able to convince reiser to randomly fill my files with NULL characters. I can't say the same for XFS, which has trashed a postgres database, my modules.conf file, my initrd.img file, and other useful files. I can't tell you how happy I am that my home directory is mounted on NFS these days. Your assertions about XFS having recovery tools are right though - I hear they're very good, but I've never used them. I can see that that's a compelling reason to choose XFS. It has been my experience though that reiser has handled the more garden-variety power failures far better than XFS. Just my experiences - I've not run either on SMP boxes or as an NFS server.
