Raspberry pi Zero2WのSSD化−２

前の記事はツールを使わずroot権限でSDカードの内容をSSDへ全コピーした、今回SDで立ち上げ後cmdline.txtを書き換えSSDのルート化をする・・・他サイトではSDカードを取り外しSSDのみで運用との記事を見受けるが筆者の環境では出来なかった

⑤SSDとSDの内容が同じ事を確認後、母艦LinuxマシンからSDとSSDを取り出しラズパイへ装着

# l SD
bin@   home/            lost+found/  proc/  service/  usr/          www/
boot/  initrd.img@      media/       root/  srv/      var/
dev/   initrd.img.old@  mnt/         run/   sys/      vmlinuz@
etc/   lib@             opt/         sbin@  tmp/      vmlinuz.old@

# l SSD
bin@   home/            lost+found/  proc/  service/  usr/          www/
boot/  initrd.img@      media/       root/  srv/      var/
dev/   initrd.img.old@  mnt/         run/   sys/      vmlinuz@
etc/   lib@             opt/         sbin@  tmp/      vmlinuz.old@

# umount SD SSD

⑥ラズパイ立ち上げ後cmdline.txtを編集

# ssh pi@iot008.local
# i@iot008.local's password:

# cat /boot/cmdline.txt 
DO NOT EDIT THIS FILE

The file you are looking for has moved to /boot/firmware/cmdline.txt
.
root@iot008:/home/pi# cat /boot/firmware/cmdline.txt
console=serial0,115200 console=tty1 root=PARTUUID=a168ebd8-02 rootfstype=ext4 fsck.repair=yes rootwait cfg80211.ieee80211_regdom=JP

console=serial0,115200 console=tty1 root=/dev/sda2 rootfstype=ext4 fsck.repair=yes rootwait cfg80211.ieee80211_regdom=JP

/boot/cmdline.txt ・・・ではなく/boot/firmware/cmdline.txtを編集する

編集　root=PARTUUID=a168ebd8-02　–> root=/dev/sda2

⑥リブートすると/dev/sda2のSSDルートで立ち上がる

ssh  pi@iot008.local

Linux iot008 6.1.0-rpi8-rpi-v8 #1 SMP PREEMPT Debian 1:6.1.73-1+rpt1 (2024-01-25) aarch64
