Neat!  There are a few problems with having your / on LVM, and this is 
one of them, but as you found, it's possible to make it all work.  I 
will try this with /home as the cached LV, because my / is on a regular 
partition on the SSD instead of on an LV.  And then see what bonnie++ or 
a similar benchmark[0] reports for /home before and after the cacheing 
change.

damned lies, statistics, benchmarks, and vendor promises.
