Comment 5 for bug 1589551

Hello,

I have thought a lot about why *all* my upgrades from 14.04 to 16.04 have failed. This does not fit with my past experience with Ubuntu, and quite frankly, it is worrisome. However, one thing does come to mind: I run LVM on virtually all my computers, and this may be the common element where the upgrader fails.

Have you sufficiently tested upgrading 14.04 LVM installations (particularly those done manually) to 16.04?

Note, there is nothing unusual or strange about my LVM installations:
/dev/mapper/ubuntu--vg-root on / type ext4 (rw,errors=remount-ro)
/dev/mapper/vgdisk-tmp on /tmp type ext4 (rw)
/dev/mapper/vgdisk-home on /home type ext4 (rw) [home]
/dev/mapper/vgdisk-opt on /opt type ext4 (rw)
/dev/mapper/vgdisk-var on /var type ext4 (rw)

or on another machine
/dev/mapper/main-root / ext4 rw,noatime,errors=remount-ro 0 0
/dev/mapper/main-tmp /tmp ext4 rw,noatime 0 0
/dev/mapper/main-boot /boot ext4 rw,noatime 0 0
/dev/mapper/main-home /home ext4 rw 0 0
/dev/mapper/main-usr /usr ext4 rw,noatime 0 0
/dev/mapper/main-var /var ext4 rw,noatime 0 0
