ROCKPro64 - Anpassen resize_rootfs.sh



  • 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           193M  7.7M  185M   4% /run
    /dev/nvme0n1p7  1.9G  1.1G  669M  62% /
    tmpfs           963M     0  963M   0% /dev/shm
    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
    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"
    

    Den Befehl ausführen
