RHV host boot into emergency mode after upgrade
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
