Currently I have my home on an 1TB disk, which is an WD Green, thus not the most quick one. I have an 2TB WD Green disk I want to use as well, and in a LVM fashion (Have heard that striped LVM could increase the perfomance).
Sadly the current /home partition isn't an handled by lvm, but a plain partition. I wonder if there are some optimal ways to convert the whole system without having to resort to an third disk as temporary storage.
i.e. I want to do 1x1TB plain partition → 1TB+2TB LVM striped while retaining all data.
