dm-raid1 is nothing to do with dmraid per-se (it's just one of the
targets dmraid might use to construct a raid set).
It is also used by pvmove - when you pvmove a volume, a temporary mirror
is constructed using dm-raid1, synchronised and then broken. After the
pvmove the newly sync'ed copy is substituted for the original PV.

I'm not sure I understand - if you're only using md and dm-crypt, why is
pvmove involved?
You can directly view the status of the mirror/pvmoved volume using
"dmsetup status" - the patch I linked to earlier corrected a problem
with the status report that prevented userspace correctly parsing the
status updates.
It does sound from your description like you may have hit a separate
problem since you mention that the pvmove does initially proceed correctly.

Bryn.
