You can add OSTs on the fly in 1.6, but not 1.4.
You could also grow the LV dynamically, but there is no way to pass
the ioctl to ext3 to do the online resizing. That might at least
be possible to implement in 1.6 because there is at least a mountpoint
for every device, but it doesn''t work quite yet.
