クラッシュ後に破損したファイルシステムがありますxfs_repair -n。ページに記載されているようにxfs_repair man損傷xfs_repair -nが検出された場合は存在し、状態1を返します。そのため、xfs_repairファイルシステムで実行してからやり直しxfs_repair -nてください。終了ステータスはまだ1です。
~によるとLinux管理用のXFS第4章xfs_repairすべての問題を解決するには、最大3回の実行が必要になることがあります。これまでこれを4回実行しましたが、終了ステータスはxfs_repair -nまだ1です。ファイルシステムがマウントされているので、原則としてデータにアクセスできますが、実際に何が破損しているのか、どのように解決できるのかを知るための別のオプションがあるかどうか疑問に思います。

Memory available for repair (2048MB) may not be sufficient.
At least 2368MB is needed to repair this filesystem efficiently
If repair fails due to lack of memory, please
turn prefetching off (-P) to reduce the memory footprint.

問題は次のとおりです。Ext4 fsを使用する別のものがあります、xfstools用の32ビットバイナリを含むリカバリCDが原因で発生しました（カーネル自体が64ビットにもかかわらず）。
そのため、最終的にルートパーティションをマウントし（問題なし）、そこでxfs_repair -n実行するためにルートパーティションに移動しました。予想通り、0 が返されました。
