Description of problem:
This is probably a rhel6 version of bug 1105732.

SCENARIO - [cache_pool_rename]

*** Cache info for this scenario ***
*  origin (slow):  /dev/sdf1
*  pool (fast):    /dev/sda1
************************************

Create a cache volume with fs data, and then rename both the cache pool and cache origin volume
Create origin (slow) volume
lvcreate -L 4G -n rename_orig_A cache_sanity /dev/sdf1

Create cache data and cache metadata (fast) volumes
lvcreate -L 4G -n rename_pool_A cache_sanity /dev/sda1
lvcreate -L 8M -n rename_pool_A_meta cache_sanity /dev/sda1

Create cache pool volume by combining the cache data and cache metadata (fast) volumes
lvconvert --yes --type cache-pool --cachemode writeback --poolmetadata cache_sanity/rename_pool_A_meta cache_sanity/rename_pool_A
  WARNING: Converting "cache_sanity/rename_pool_A" logical volume to pool's data volume.
  THIS WILL DESTROY CONTENT OF LOGICAL VOLUME (filesystem etc.)
