I too have found the hard way that yanking the power on XFS (or just hitting reset at a bad time) is a very bad idea. All the files that had pending writes just end up as the correct length of zeros. When this is includes your package database, perl binaries and a load of other libs, this is quite bad.

The xfs_repair tool did do a pretty-good repair job (once I fixed it so it ran! http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=414079) but it did take about 5 hours to do it on a pair of 200GB mirrored drives. Then I got to re-install everything to fix the damage.

About 3 days faff in total. Fair dues though - there was no user-data loss and the system was recoverable, but I've never had this trouble with reiser3 on my laptop or ext3 on other boxes. So, yes, XFS is a really nice filesystem (live resizing, nice and fast) but I'd avoid it unless there is a UPS around.
