4:10 a.m.
I've installed oVirt Node 4.2 on one of my servers. Recently I've upgraded the
kernel version to 3.10.0-957.5.1.el7.x86_64.
After such update, I've rebooted the server to take effect and then the /boot
partition cannot be recognized. The server then enters emergency mode and I've tried
to run the command blkid but I cannot find the uuid of /boot and /boot/efi.
Before reboot:
# blkid

Any ideas what caused this?
