[Bug 1874381] Re: LVM device unavailable after 18.04 to 20.04 upgrade Timed out waiting for device /dev/mapper/s5lp8--v g-home

[veribaka]

Reporting back:

"sudo vgck -t vg" reports that no changes would be made, it seems to be
looking in /dev/sda rather than /dev/nvme0n1.

"sudo vgscan" first reports that /dev/sda open failed and then
successfully detects the vg using metadata type lvm2.
