タイトルの通りなんですが，今朝（2023年2月2日(木)）findコマンドを2つ同時にかけたら，システムが無応答になってしまい，電源リセットしたらfile systemにエラーがあるというので，fsckをかけたらエラーがボロボロ出て，修復はできましたが，不安なのでformatして今朝のバックアップに戻しました．<\/p>\n\n\n\n

ファイルシステムが壊れた原因については分かりませんが，多分SSDをか弱いUSBドライバーで動かしているので過重負荷のためドライバーがダメになったのだと思います．知らんけど．<\/p>\n\n\n\n

修復作業のため，同日の午後はしばらくシステムが止まっていました．<\/p>\n\n\n\n

また，久しぶりの作業なのでいろいろ手順を忘れて，なかなか再起動せず焦りました．<\/p>\n\n\n\n

以下は今後の自分のためのメモです．<\/p>\n\n\n\n

    \n
  1. バックアップからのコピーはたぶん以下のようなコマンドを使う<\/li>\n<\/ol>\n\n\n\n
    cd \/\u5fa9\u65e7\u3055\u305b\u308b\u30b7\u30b9\u30c6\u30e0\u306e\u30eb\u30fc\u30c8\nrsync -artlvd --sparse --inplace --numeric-ids \/\u30d0\u30c3\u30af\u30a2\u30c3\u30d7\u306e\u30d1\u30b9\/ .<\/pre>\n\n\n\n
    これでたいがい時間がかかります<\/p>\n\n\n\n
      \n
    1. 終わったら，復旧されるシステムのルートに\/devはないはずですから，用意してある\/devをコピーする（\/root\/devsにあるはず）<\/li>\n\n\n\n
    2. formatし直すとPARTUUID等が変わるので，\/bootのcmdline.txtと\/etc\/fstabを新しいPARUUID等で更新する<\/li>\n\n\n\n
    3. あとはターゲットシステムにディスクを接続して，祈りながら起動をかける<\/li>\n\n\n\n
    4. バックアップにはロックファイルなどもあるので，起動したらすぐに再起動をかける<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
