[Bug 1843623] Re: LVM volumes not activated during boot after upgrade to 18.04 LTS

[Marius Gedminas]

If I run pvscan --cache -aay in the systemd emergency console, all
logical volumes get activated and the system then proceeds to boot
normally.

It seems like for some reason udev is not running pvscan for me?

Title:
  LVM volumes not activated during boot after upgrade to 18.04 LTS

Status in lvm2 package in Ubuntu:
  New

Bug description:
  I've upgraded a server from Ubuntu 16.04 LTS to 18.04 LTS and now it
  fails to activate LVM volumes during boot (which causes systemd to
  stop in the middle of the boot process and ask me to fix this on the
  console without starting up services like SSH).

  The root partition, which is also on LVM, gets activated (by the
  initramfs I assume), but none of the other ones are.

  Everything worked fine on xenial, so I don't think this is a duplicate
  of 1573982?
