Wie Ihr wisst, habe ich ein System mit einer NVMe SSD (960 EVO 256GB). Die tauschen wir heute mal aus.
Auf der SSD liegt das / Verzeichnis. Als erstes sichern wir es mal auf eine angeschlossene 1TB HDD.
rock64@rockpro64v2_0:~$ sudo dd if=/dev/nvme0n1 of=/mnt/backup/nvme.img bs=4MB
488397168+0 records in
488397168+0 records out
250059350016 bytes (250 GB, 233 GiB) copied, 5064,37 s, 49,4 MB/s
Danach schalten wir das System mal aus - Hardware umbauen 
Hardware ist drin. Jetzt brauchen wir irgendeine SD-Karte die bootet. Die vorhandene ist ja so geändert, um das Rootverzeichnis von der NVMe-Karte zu laden. Wenn da nichts liegt, scheitert der Bootvorgang.
ROCKPro64 gestartet. HDD mounten.
sudo mount /dev/sda1 /mnt
Dort liegt das Image nvme.img Das muss jetzt auf die NVMe-Karte.
rock64@rockpro64:/mnt$ sudo dd if=/mnt/nvme.img of=/dev/nvme0n1 bs=4MB
62514+1 records in
62514+1 records out
250059350016 bytes (250 GB, 233 GiB) copied, 2508.21 s, 99.7 MB/s
bs=4MB hatte ich oben, beim Sichern, vergessen 
Und ich wunder mich, das das so lange dauert. Der Befehl oben ist entsprechend korrigiert. Nachdem dd fertig ist , schalten wir den ROCKPro64 wieder aus.
sudo shutdown now
Wenn ich jetzt keinen Denkfehler habe, muss nach Einsetzen der alten SD-Karte das System wieder ordentlich starten und / auf der NVMe-Karte liegen.
So, das System ist gestartet. Beim Booten hat es etwas gedauert.

Aber, ich habe keine Ahnung was hier los war. Auf alle Fälle ist es gestartet. Mal nachsehen.....

Aber, ein kleines Problem. Ich habe es erwartet. Das / Verzeichnis ist zu klein, die NVMe-Karte hat eine Kapazität von 500GB. Dann mal ran...
Ausschalten
sudo shutdown now
Wieder die SD-Karte wechseln. Starten. Überblick verschaffen...
sudo fdisk -l
Danach

Ganz ehrlich, ich war nicht so sehr davon überzeugt das das so geht. Aber, wieder runtergefahren, SD-Karte gewechselt und neugestartet. Und, was sehen wir - es geht!

Mal geschaut ob meine Testinstallation von Grav läuft, das macht sie aber nicht. Bad Gateway Aber, durchs schrauben an meinem Rootserver habe ich ein wenig gelernt. Bad Gateway, da läuft php7.2-fpm nicht. Nachschauen...

Gut, mein Tipp war richtig

. ok
Tada, Grav läuft wieder. Puh, Glück gehabt LOL Warum der Dienst jetzt automatisch nicht gestartet ist, schau ich mir dann nochmal in Ruhe an. So zum Abschluss noch ein iozone
