Create big sparse file, 'mdconfig -af' it, create geli on it, mount and start moving files from the 'outer' filesystem (the one on which sparse file is created) to the 'inner' (encrypted with eli) one. If outer one has softupdates enabled, move will soon stop on 'wdrain'. Disabling softupdates makes the problem dissappear. >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted:
