Hi Handian Sudianto,Please try following trouble shooting steps:
As the error shows that /dev/mapper/rhel-root
is missing, first check if the disk is recognized.
If you find your root partition, try mounting it manually. Once the filesystem is mounted, change root to the installed system.
Since the migration changed the underlying hypervisor, the disk UUIDs may have changed. Verify them, If the UUIDs do not match those from blkid
, update /etc/fstab
with the correct ones.
Once /etc/fstab
is corrected, rebuild the initramfs.
