皆さん、こんにちは、
EC2インスタンスは、ボリュームをデタッチして再アタッチした後、"1/2チェックに合格"のみで初期化されています(特定のデバッグ目的で実行しました)。したがって、私はLinuxサーバーにログインできません今(PuTTYを使用して..ネットワークエラーが表示されます)ここにありますインスタンスを終了することにした場合に備えて取得する必要があるいくつかの複雑なスクリプト。
SAP HANAクラウドアクセスにのみ使用するため、EC2プログラミングについてはよくわかりません。以下に示すインスタンスのシステムログを生成しました。

専門家がこの問題について私を助けてくれることを願っています。
ありがとう
私もこれを経験しました-2番目のヘルスチェックはネットワーク接続であり、それが解決されるまでSSHは機能しません(明らかに)。私は提案します
また、同じAZで新しいEC2インスタンスを起動し、異常なインスタンスからボリュームを切り離して、新しいインスタンスのセカンダリ/ターシャリボリュームとしてマウントすることもできます-それを調べるか、スクリプト/ファイルを取得しますあなたが必要です。
申し訳ありませんが、それ以上具体的なアドバイスはできませんが、/ local /パーティションが読み取れなくなったのではないかと思います。
