Bug#406454: closed by Bastian Blank <waldi@debian.org> (Re: Bug#406454: pvmove: fails to move within the same physical volume)

Reopening as wishlist. There is no reason pvmove should not be able
to do this.

That should be made clearer then in both the manpage and the error
message. If pvmove can't move PEs on the same PV then it should check
that they differ and complain about it specifically.

The --alloc parameter is not documented outside the synopsis. What is
the 'AllocationPolicy' parameter? What values can it hold and what
value do I need to move withint a PV?

If --alloc .... allows to move within a PE then pvmove should
automatically use that setting when it detects that source PE and Dest
PE are the same. Maybe with the restriction that the Dest PE must have
a starting PE or full PE-PE range.
