ROCKPro64 - Anpassen resize_rootfs.sh

[FrankM]

Nachdem wir nun von der PCIe NVMe SSD booten können, haben wir ein Problem, die Root Partition ist zu klein. Diese muss vergrößert werden.

Macht das bitte erst auf einem Testsystem!!!

rock64@rockpro64:~$ df -h  
Filesystem      Size  Used Avail Use% Mounted on
udev            960M     0  960M   0% /dev

tmpfs           5.0M  4.0K  5.0M   1% /run/lock
tmpfs           963M     0  963M   0% /sys/fs/cgroup
/dev/nvme0n1p6  112M  4.0K  112M   1% /boot/efi
tmpfs           193M     0  193M   0% /run/user/1000

Kamil hat ein Script mit Namen

resize_rootfs.sh

das liegt in

/usr/local/sbin

Inhalt

#!/bin/bash

if [[ "$(id -u)" -ne "0" ]]; then
        echo "This script requires root."
        exit 1
fi

dev=$(findmnt / -n -o SOURCE)

case $dev in
        /dev/mmcblk*)
                DISK=${dev:0:12}
                NAME="sd/emmc"
                ;;

        /dev/sd*)
                DISK=${dev:0:8}
                NAME="hdd/ssd"
                ;;

         
        *)
                echo "Unknown disk for $dev"
                exit 1
                ;;
esac

Das passen wir jetzt mal für NVMe an

#!/bin/bash

if [[ "$(id -u)" -ne "0" ]]; then
        echo "This script requires root."
        exit 1
fi

dev=$(findmnt / -n -o SOURCE)

case $dev in
        /dev/mmcblk*)
                DISK=${dev:0:12}
                NAME="sd/emmc"
                ;;

        /dev/sd*)
                DISK=${dev:0:8}
                NAME="hdd/ssd"
                ;;

        /dev/nvme0n1*)
                DISK=${dev:0:12}
                NAME="pcie/nvme"
                ;;


        *)
                echo "Unknown disk for $dev"
                exit 1
                ;;
esac

echo "Resizing $DISK ($NAME -- $dev)..."

set -xe

# move GPT alternate header to end of disk
sgdisk -e "$DISK"

# resize partition 7 to as much as possible
echo ",+,,," | sfdisk "${DISK}" -N7 --force

# re-read partition table
partprobe "$DISK"

# online resize filesystem
resize2fs "$dev"

echo "Resizing $DISK ($NAME -- $dev)..."

set -xe

# move GPT alternate header to end of disk

# resize partition 7 to as much as possible
echo ",+,,," | sfdisk "${DISK}" -N7 --force

# re-read partition table
partprobe "$DISK"

# online resize filesystem
resize2fs "$dev"

Den Befehl ausführen

Vor dem Neustarten mal abwarten bis die LED der SSD aufhört zu blinken! Sicher ist sicher

Konnte Kamil davon überzeugen, das das eine gute Idee ist. Wir sind ja alle ein wenig faul

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

Perfekt. Danke Kamil!
