lvm2/test/t-mirror-lvconvert.sh
Jonathan Earl Brassow 6c6ce2ba0e Test all combinations of mirror conversion, both while the LV
is active and while it is in-active.

+for i in $(seq 0 4); do
+       for j in $(seq 0 4); do
+               for k in core disk mirrored; do
+                       for l in core disk mirrored; do

The testing code still needs some improvement.  I'd like to add
the ability to test specifying the PVs to be added/removed during
a convert.  It will also be important to test partial PV
specification during down converts (i.e. request to remove more
mirror images than we have provided PVs for).
