I've both heard about and experienced first-hand data loss (pretty 
severe actually, some incidents pretty recent) with XFS after power 
failure. It used to be great for performance (not so great now that Ext4 
is on the rise), but reliability was never its strong point. The bias on 
this list is surprising and unjustified.

FWIW, I was at SGI when XFS for Linux was released, and I probably was 
among its first users. It was great back then, but now it's over-rated.
