I have lost data in XFS files systems, but that hasn't happened to me
in a decade, and I'm not particularly careful about powercycling.  I
use XFS exclusively for those filesystems that are going to be shared
out remotely because I can extend XFS filesystems without umounting
the disks.  So, my file services all come from XFS build on LVM lv's.
Run out of space on /home?   Well, then, I do an "lvextend" and a
xfs_growfs and the problem has gone away.
