# dmsetup targets
Unknown command

dmsetup [--version] [-v|--verbose [-v|--verbose ...]]
        [-r|--readonly] [-j|--major <major>] [-m|--minor <minor>]

So I got an updated version of dmsetup and now I get;
# dmsetup targets
mirror           v1.0.1
striped          v1.0.1
linear           v1.0.1
error            v1.0.1

but pvmove -tv /dev/hdf4 still fails with;

  ABORTING: Temporary mirror activation failed.
