RHV host boot into emergency mode after upgrade

Solution Verified - Updated -

Issue

  • After upgrading the RHV host, it is booting into emergency mode with the error about the unavailability of logical volumes.
  • The host is having LVM filter configured.
  • I have an lvm filter that allows only the boot disk to be seen on the host, and nothing else, ie: (lvm.conf):
filter = [ "a|^/dev/sda2$|", "r|.*|" ]
  • When upgrading to the latest RHV-H, host fails during reboot. (stops at emergency shell)
  • /boot is now a /dev/mapper/xyz device

Environment

  • Red Hat Virtualization (RHV) 4.2, 4.3
