Title:
LVM in 16.04 cannot mount LVM Cached Volumes created in 15.10
Status in lvm2 package in Ubuntu:
Confirmed
Bug description:
I'm test driving Ubuntu Mate Beta 1 (from USB) on a machine that uses
LVM caching. (I use some SSD to cache old hard drives). My LVM setup
was created with Linux Mint Debian Edition - Betsy release.
The system cannot mount these cached volumes due to the following
error reported by 'pvs':
ubuntu-mate at ubuntu-mate:~$ sudo pvs
LV CacheArchive has invalid cache's feature flag.
LV CacheArchive is missing cache policy name.
Internal error: LV segments corrupted in CacheArchive.

I did a bit of googling and found a similar report for upgrades from
Fedora 21 to Fedora 23. See
https://bugzilla.redhat.com/show_bug.cgi?id=1282188.
I'll annotate this bug with the LVM version from my existing Debian
based configuration in a few minutes.
This is a show-stopper for me because I use LVM caching on both of my
PCs. It's a great way to marry a 256 GB SSD with a 2 TB hard drive. I
keep the OS and some key partitions on the SSD and then use the rest
of the SSD to cache the hard drive.
