Can you add a mirror to any LVM after creating it without
making provisions ahead of time as you must when setting
up raid devices?   I have found it useful to create 'broken
raid' devices that could be mirrored on demand to external
drives and have been thinking about doing it over iscsi too.
However it doesn't seem possible to install the system on
a raid with missing devices.
