    Seit Release 0.10.10 ist das automatische Vergrößern der Root Partition mit drin 🙂

    0.10.10: Support automated resize when booting from nvme

    Einfach das Image auf die NVMe SSD schreiben, ab in den ROCKPro64 und fertig! Nach dem Booten wird die Partition dann automatisch auf die maximal mögliche Größe erweitert.

    Kamil hat das Script auch ein wenig angepasst.

    case $dev in /dev/mmcblk?p?) DISK=${dev:0:12} PART=${dev:13} NAME="sd/emmc" ;; /dev/sd??) DISK=${dev:0:8} PART=${dev:8} NAME="hdd/ssd" ;; /dev/nvme?n?p?) DISK=${dev:0:12} PART=${dev:13} NAME="pcie/nvme" ;;

    Das Resultat bei einer Samsung 979 EVO mit 500GB Speicher

    rock64@rockpro64:~$ df -h Filesystem Size Used Avail Use% Mounted on udev 918M 0 918M 0% /dev tmpfs 192M 5.2M 187M 3% /run /dev/nvme0n1p4 459G 1.2G 439G 1% / tmpfs 957M 0 957M 0% /dev/shm tmpfs 5.0M 4.0K 5.0M 1% /run/lock tmpfs 957M 0 957M 0% /sys/fs/cgroup /dev/nvme0n1p3 229M 44M 169M 21% /boot /dev/nvme0n1p2 12M 0 12M 0% /boot/efi tmpfs 192M 0 192M 0% /run/user/1000

    Perfekt. Danke Kamil!

    Hallo FrankM,
    schade das Du mir nicht weiter helfen kannst, aber danke für Deine schnelle Antwort.
    Mit dem Bugreport kenne ich nicht aus, bin noch leihe.

    Einen schönen Abend noch.

    Winne

    Mal ein Test was der Speicher so kann.
