During boot I get the message

block nvme0n1: No UUID available providing old NGUID

When I try to mount the lvm I get the message

~# mount /dev/mapper/fedora /sd1
mount: /sd1: fsconfig system call failed: /dev/mapper/fedora Can't lookup blockdev.
      dmesg(1) may have more information after failed mount system call.


The lvm has two physical volumes on /dev/nvme0n1p5 and /dev/nvme0n1p6

The lvm /dev/mapper/fedora has a different OSand boots and runs as expected. Another fedora f42 installation accesses the lvm with no problems.

How do I get this installation of f42 to access the lvm?


What does lsblk -f report?
