（少なくとも）ディスクで不良ブロックが発生しました。残念ながら、XFSデータ構造が見つかり、一部のファイルシステムメタデータが失われます。バックアップがありますように。

表示される正確な属性は、ディスクごとに異なりますが、ほとんどがディスクに回復していない不良セクタの数を知らせる197および/または198があります。上記の出力では、＃5は、FAILING_NOWそのタイプはですPre-fail。これは、ディスクファームウェアが24時間以内にディスクに障害が発生すると予想することを意味します。失敗した属性、特に事前に失敗した属性がある場合はディスクを交換します（まだ保証期間が残っている場合はRMAを実行できる必要があります）。
smartctlがない場合
smartctlがなければ、今はそうです。いいえインストールする時間です。
重要な次のステップ
コンピュータディスクに重要なファイル（特にバックアップされていないファイル）がある場合は、そのファイルを別のディスク、USBフラッシュドライブ、ネットワーク共有などにコピーしてみてください。ファイルシステムが破損し、今回が簡単に破損する可能性がある最後の機会かもしれません。
リアルタイムシステムを使用してsmartctl、xfs_repairを実行する
まだインストールしていない場合は、smartctlライブシステム（CD、USBスティックなど）から再起動し（重要なデータをコピーした後！）、そこからsmartctlを実行できます。xfs_repairライブシステムを使用してファイルシステムの回復を試みることもできます。 （最初にマンページを読んでくださいxfs_repair。私はXFSの経験があまりないことを認めています。）
過去1〜2年以内に作成されたディスクにはスペアセクタがあり、そのうちの1つは次の書き込み時に不良セクタを交換するために使用されます。smartctl -A通常、この操作が完了した回数を示す属性があります。
ファイルシステムの回復後
以前に重要なファイルを入手できなかった場合は、今すぐやり直してください。
破損の重大度（欠落しているファイルの数と不足しているファイル）によっては、一部のパッケージを再インストールする必要があります（dpkg -iまたは使用apt-get install --reinstall）、破損が深刻な場合はオペレーティングシステムを再インストールする必要があります。
もちろん、最近完全なシステムバックアップがある場合は、バックアップから復元するのが最も簡単です。
今後このようなことが発生しないようにする方法
mdraid RAID1ミラーリングで2つのディスクを使用すると、カーネルは他のディスクのセクタを読み取って誤ったブロックを処理できます。その後、正しいデータを書き換えてディスクがスペアセクタを使用できるようにします。同じディスク上の2つのパーティション間でRAID1を実行することもできます。これにより、空き容量が半分になりますが、不良セクタから保護されます（ただし、ディスク全体の障害を防ぐことはできません）。
一部のファイルシステム（たとえば、「冗長」モードのbtrfs）は、不良セクタから保護しながら、メタデータまたはデータの2つのコピーを保持できます。
