Description of problem:
I feel like this has come up before but I couldn't find an open bz.

[root@host-117 ~]# lvconvert -m 0 centipede/centi_base /dev/sde2
  Logical volume centipede/centi_base converted.


# Shouldn't this linear now be on /dev/sde2?

Comment 2 Corey Marthaler 2016-09-06 19:01:30 UTC 
I stand corrected, this works as designed.

From lvconvert man page:

       Convert a mirror LV to a linear LV, freeing physical extents from a specific PV:
       lvconvert --type linear vg/lvol1 /dev/sda
