btrfs ファイルシステムに問題があります。起動はうまくいきますが、使用中に一部のプログラムを実行している間、突然端末にこのエラーが発生します。
I/O error brfs unable to open /dev/sda5 read only file system
これにより、コンピュータをインストールまたは再起動できなくなります。
私がしたこと：sudo btrfs check /dev/sda5

また、smartctl -x /dev/seaを実行しましたが、気流温度を除いて出力は問題ありませんでした。
dmesg出力を得ることができます

私のドライブのsmartctl出力にも同じことが当てはまります。インテリジェント制御出力
この質問は実際にここに投稿された質問と似ています。ここにリンクの説明を入力してください私のドライブはHDDタイプであるだけです。
