ALERT! /dev/mapper/pve-root does not exist. Dropping to a shell!

Disks are nvme, same size .
boot disk is sdb:

Assuming you have all VM/LXC backed up, I would reinstall PVE and switch to ZFS

Problem solved. In the BIOS of the Dell Optiplex 7060 AHCI insted of RAID must be selected in order to complete the boot process. To clone the disk just use DD. Exchange the disks and it will boot perfectly. No changes o grub rebuild are needed.
