0. Create an origin LV we wish to cache (yours may already exist)
# lvcreate -L 10G -n lvx vg /dev/slow
Already Exists
1. Create a cache data LV
# lvcreate -L 1G -n lvx_cache vg /dev/fast
[root@cheeseboy mysql_python]# vgextend dataraid10 /dev/md30 /dev/md31 /dev/md32 /dev/md33 /dev/md34
[root@cheeseboy mysql_python]# lvcreate -i 5 -I 32 -l 100%FREE -n dataraid10ssdcache dataraid10
Logical volume "dataraid10ssdcache" created
2. Create a cache metadata LV
# lvcreate -L 8M -n lvx_cache_meta vg /dev/fast
[root@cheeseboy mysql_python]# vgextend dataraid10 /dev/md35
[root@cheeseboy mysql_python]# lvcreate -i 1 -I 32 -L 20G -n dataraid10metadata dataraid10
Ignoring stripesize argument with single stripe
Logical volume "dataraid10metadata" created
3. Create a cache pool LV specifying cache mode "writethrough"
# lvconvert --type cache-pool --poolmetadata vg/lvx_cache_meta \
--cachemode writethrough vg/lvx_cache
[root@cheeseboy mysql_python]# lvconvert --type cache-pool --poolmetadata dataraid10/dataraid10metadata --cachemode writethrough dataraid10/dataraid10ssdcache
Converted dataraid10/dataraid10ssdcache to cache pool.
4. Create a cache LV by combining the cache pool LV and origin LV
# lvconvert --type cache --cachepool vg/lvx_cache vg/lvx
[root@cheeseboy mysql_python]# lvconvert --type cache --cachepool dataraid10/dataraid10ssdcache dataraid10/dataraid10one
dataraid10/dataraid10one is now cached.
[root@cheeseboy mysql_python]# vgchange -a y dataraid10 [==> causes crash]

I've read that disabling the lv2-lvmetad daemon might yield some results. This did not change the outcome.
