Title:
  [version bump] Please include LVM2 version > 2.02.106

Status in One Hundred Papercuts:
  Confirmed
Status in “lvm2” package in Ubuntu:
  Confirmed

Bug description:
  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.

  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.
