For 3.8 issues, read dm-devel around https://www.redhat.com/archives/dm-devel/2013-February/msg00086.html (I queued the dm-side fixes for linux-next earlier today) For pvmove, check exactly which version and whether discards are enabled: there was a userspace bug for a short period some time ago when discards were enabled.
