Being that I'm still having this issue on Ubuntu 15.10, I can only conclude that this appears to be a design philosophy at Canonical rather than a bug. Logical volumes that are not necessary for system boot and/or are not on the primary disk where the OS is installed are not made available / mounted on (re)boot!
It is much better that the system comes up rather than waiting for a user input at (re)boot. Case closed, at least for me! ak. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lvm2 in Ubuntu. https://bugs.launchpad.net/bugs/147216 Title: LVM filesystems not mounted at boot Status in lvm2 package in Ubuntu: Confirmed Bug description: My system has a root filesystem in an LVM logical volume, backed up by two MD RAID-1 arrays. It fails to boot propertly after upgrading to kubuntu gutsy gibbon prerelease (latest packages as of today). In order to boot it, I have to specify the break=mount boot option, then subsequently run lvm vgscan lvm vgchange -a y to manually enable the LVM volumes. I should note that the MD arrays are started successfully.
