.I \-\-merge
Merges a snapshot into its origin volume. If both the origin and snapshot volume
are not open the merge will start immediately. Otherwise, the merge will start
the first time either the origin or snapshot are activated and both are closed.
Merging a snapshot into an origin that cannot be closed, for example a root
filesystem, is deferred until the next time the origin volume is activated.
When merging starts, the resulting logical volume will have the origin's name,
minor number and UUID. While the merge is in progress, reads or writes to the
origin appear as they were directed to the snapshot being merged. When the
merge finishes, the merged snapshot is removed.
