Dave,

thanks for your quick reply and detailed analysis.

For the benefit of other readers, I wish to add that the same problem
occurs when creating lvm mirrors (e.g. "lvconvert -m1 vg/lvol"), which
is not surprising since pvmove works itself by creating a mirror.
Consequently, mirror creation should also be avoided until the root
cause of the problem is eliminated.

Cheers,
Matteo
