create dm-cache backed logical volume in 3 easy steps!

1. Create a new/Find your old logical volume
   This volume may already contain data/filesystems and should be placed on slow(er) storage.
   
#
# lvcreate -n home -L100G vg_orange
#

2. Create your CachePool aka Backend
   A CachePoolLV contains a CacheDataLV and a small CacheMetaLV, both will be created automatically. Place this CachePoolLV on your fast SSD

   #
# lvcreate --type cache-pool -n home_cache -L 30G vg_orange /dev/sda
#


3. Convert your Origin into a CacheLV

   #
   # lvconvert –type cache –cachepool home_cache vg_orange/home
   #

Now you may access your Origin just like you did before, but should become faster after a while (because cache needs to be filled)
