[linux-lvm] Raid1 -> linear conversion = destroyed data

I used lvconvert -m 1 --type raid1 to clone my root volume onto a new
drive, and then used --splitmirrors to split off the original volume
as a backup while I worked off the new drive for a few days.  I then
decided the new drive was working well and used lvconvert -m 0 to
convert the volume back to linear.  Instead of dropping the split off
original leg, lvm dropped the NEW copy and redirected all IO to the
OLD data, causing massive filesystem corruption.

This is on Ubuntu 14.10 using lvm 2.02.98 and linux 3.16.
