I have cloned my disk to a bigger one using clonezille from Manjaro USB Live which worked great. Now after swapping the disks I get this error:
ERROR: device ‘UUID=<device_uuid>’ not found. Skipping fsck
mount: /new_root: can't find <device_uuid>.
You are now being dropped into an emergency shell.
sh: can't access tty: job control turned off
I have seen this thread Mount: /new_root: can't find <device_uuid> with similar problems, but when I run manjaro-chroot -a after booting again in Manjaro USB Live I get
>>> sudo su
>>> [manjaro manjaro]# manjaro-chroot -a
grub-probe: error: cannot find a GRUB drive for /dev/sda1. Check your device.map.
grub-probe: error: cannot find a GRUB drive for /dev/sda1. Check your device.map.
==> ERROR: No Linux partitions detected!
>>>[manjaro manjaro]#
What is also strange, that I do not find the disk on KDE Partition Manager. But in BIOS it seems to find the disk.
I did connect the new M2 SSD via case and USB. Then cloned the old disk to the new one via clonezilla. After the cloning both disks were shown in KDE Partition Manager as expected. Then finally switched the disks.
I guess I did something wrong on cloning and have to do more homework. I put the disk back in the case and now I can boot it analog as my USB without any problem.
Even as I made an error and gave you not so good instructions (I have edited my comment now), it seems by the output of the lsblk command, that your NVMe drive is not being detected, at least when you boot from the liveUSB. Can you check that the drive is firmly in place? Is there any other thing that can affect the visibility of the drive?
You have be able to see the drive to chroot into it and change fstab file to replace the old UUID with the new UUID
No, you did good. This is the normal behavior. You have to update the UUID after the cloning. It’s just that.
