I guess that makes sense... If i were to choose between this or mdadm with linear mode, which would be more efficient? i'm guessing it'd be mdadm. and i wouldn't need anything more than this... I know LVM is much more flexible though, but i don't necessarily need all that abstraction functionality. I plainly want to enlarge my /. if i were to use mdadm linear mode, could i migrate to this live? i'm guessing not... especially since it's the /. 1. can i create the linear mode raid without losing data? ie: the first partition doesn't need to be changed, right? I guess this could work. 2. can I switch the / device while it's being used? i remember that initrd have a command that does this (pivot_root) or something... I guess this is really going off-topic. it would be so much better if the propagation would work...
