In lvm2 version 2.02.105 lvconvert gained a --splitsnapshot option to allow people to wipe snapshot content before releasing the extents for reallocation.
--splitsnapshot Separates SnapshotLogicalVolume from its origin. The volume that is split off contains the chunks that differ from the ori- gin along with the metadata describing them. This volume can be wiped and then destroyed with lvremove. The inverse of --snap- shot.
Nice to know ... we use the snapshot feature heavilyin our virtualization, but as: CentOS 6 is at lvm2-2.02.100-8.el6.x86_64, and C 5 at lvm2-2.02.88-12.el5, we will need to wait a bit before relying on its presence. Any chance of a re-basing / refresh / backport at least into RHEL 6 (we have only one Xen oriented dom0 at this point on C5)? Thanks --Russ herrold
