Raspberry pi Zero2WのSSD化−3
前回の記事で/dev/sda2のSSDルートで立ち上がった、次にSSDのファイル拡張とSWAPファイル追加をする
⑦SSDのファイル拡張・・・raspi-config–> Advanced Options –> Expand Filesystem –> rebbot

Welcome to fdisk (util-linux 2.38.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
This disk is currently in use - repartitioning is probably a bad idea.
It's recommended to umount all file systems, and swapoff all swap
partitions on this disk.
Command (m for help):

Broadcast message from root@iot008 on pts/1 (Sun 2024-06-16 18:01:26 JST):
The system will reboot now!
⑧再起動後再度ログイン、拡張された事を確認しSWAPファイルの追加

スワップファイル/var/sawpが追加された
この後upgradeで中にSSDアクセス・ランプ点滅で長時間固まったなので/etc/dphys-swapfileを編集して容量を増やす・・・SD版IOT-HouseはSDのスワップを無効化しているSSD版で運用する場合はdphys-swapfile有効化が必要
