私のサーバーでCentOSを実行するのに問題があります。古いデータの削除に失敗したバックアップスクリプトエラーのため、システムパーティション "md3"(raid1) がいっぱいになりました。その結果、私のCentOSシステムにアクセスできなくなりました。
サーバーを再起動しようとすると、システムは "md3"パーティションに関連付けられている/ sysrootをマウントできません。最終的にプロセスがタイムアウトし、システムを起動できなくなります。
また、いくつかのクリーンアップを実行するために回復モードで "md3"にアクセスしようとしましたが、mountコマンドはパーティションをマウントできませんでした。エラーは表示されず、プロセスは無期限に中断されます。 （読み取りモードでのみマウントしようとしましたが、詳細は表示されません。）
追加の状況のためにRAID1とHDDの状態を確認しましたが、すべてが正常です（ホスティングサポートで確認済み）。

この問題を解決する方法について提案がある人はいますか？
あなたのアドバイスと助けに心から感謝します。
答え1
いくつかのテストの後、クイックアップデートを実行しました。
xfs_repair -L /dev/md3
これは破損したXFSログを削除するためのものです。明らかに注意してください。常にバックアップする必要があります。これにより、データが破損したり、さらに失われたりする可能性があります。
ありがとうございます。
