Now I started moving a lot of data onto the volume and iostat said all the data was being written to md9. Why that array? How does it decide which physical volume to write to?
This does not exactly explain how it picks them at creation, but you can use the command "lvdisplay -m" or "lvdisplay -m /dev/vgname/lvname" to show which logical blocks are mapped to which physical blocks of the underlying pv.
