How can I have a writable snapshot ? LVM snapshots are supposed to
be read-only, aren't they ?

But indeed if the journal data has not been committed on the original
volume when the snapshot is taken, then the snapshot may have false data
in it as, due to its read-only nature, it is not able to catch up the
uncommitted journal data... Am I missing something ?
