This indicates that it "worked" that way on some versions rhel5 but
does not work that way on rhel6 in a number of versions.


I would suspect depending on exactly what version you are using that
it is a bug.

I know up to at least 5.7 there are some bad LVM bugs when you are
doing abnormal things (mirroring, pvmoves with lv with multiple
extents), there are probably other bugs I don't know about.

I would suggest unmirroring it, and just doing a straight pvmove to
the new device, mirroring it in the middle would just appear to
complicate things.
