Subject: [LVM2 PATCH] (1/3) Check cow != origin in commands
Date: Thu, 09 Aug 2007 13:54:35 -0400 [thread overview]
Message-ID: <46BB54DB.5010608@ce.jp.nec.com> (raw)
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,
