The primary difference that I see for degraded boot is this error just ahead of activating volume group 'dataone' 'watershed sh -c '/sbin/lvm vgscan; /sbin/lvm vgchange -a y''(err) ' device-mapper: reload ioctl on failed: Invalid argument' and also after that point the 55-dm and 56-lvm rules

[Touch-packages] [Bug 1351528] [NEW] boot fails on raid (md raid1) + LVM (combined / + /boot) + degraded

Public bug reported: Trusty installation is combined root + /boot within LVM on top of mdraid (type 1.x) RAID1 with one missing disk (degraded). [method: basically create the setup in shell first then point install at the lvm. at end of install create a chroot and add mdadm pkg] boot fails

[Touch-packages] [Bug 1351528] Re: boot fails on raid (md raid1) + LVM (combined / + /boot) + degraded

here is an interesting find: replacing the missing disk (mdadm --add /dev/md0 /dev/sdb1) and waiting for sync to complete leads to proper booting system the system continued boot even after I --failed and --removed the second disk. I could not return the system to it's original boot fail state
