Public bug reported:

LVM2 introduced LVM Caching with 2.02.106 to allow backend cache (SSD)
for other block storage (HDD).

The packages are built in Debian Sid, and it would be good to also
include this package in Ubuntu.

https://packages.debian.org/sid/lvm2
http://metadata.ftp-master.debian.org/changelogs//main/l/lvm2/lvm2_2.02.109-1_changelog

RHEL7 has this feature as a tech preview:
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/7.0_Release_Notes/chap-Red_Hat_Enterprise_Linux-7.0_Release_Notes-Storage.html

Though Trusty's kernel version is too old to support LVM Cache, Utopic's
3.16 kernel should work out of the box. Support was added  in 3.14.

Benefit over bcache and dm-cache is that the caching LV can be added and
removed without the need for reformatting the FS.
