It's amateur hour... yes I did unmount before running xfs_repair or it
fails. And I also did the test on conventional LV, not thinp.

If I do the same test on a thinp LV, I consistently get more errors
(than conventional LV) when I run xfs_repair, probably because there
are 4x the AG's on thinp LV's for some reason.
