[lvm-devel] [LVM2 PATCH] (1/3) Check cow != origin in commands

[Jun'ichi Nomura]

Hi,

Currently we can do this strange thing:
  # lvconvert -s testvg/lvol0 testvg/lvol0
  Logical volume lvol0 converted to snapshot.

It means testvg/lvol0 is both origin and cow of the snapshot.

Once we create such a LV, we cannot remove it.

lvconvert should check its parameter and
the attached patch does it.

Thanks,
