リモートコンピュータにファイルがあります（正確に誰がそのファイルを作成したのかわからないため）、削除する必要があります。
user@machine:~/folder$ ls
lift_proto.db.lock.db
そして権限は次のとおりです。
user@machine:~/folder$ ls -al
total 12
drwxrwxrwx 2 root root 4096 2012-03-06 20:57 .
drwxr-xr-x 26 user group 4096 2012-03-06 20:53 ..
-rw-r--r-- 1 root root 126 2012-03-06 20:57 lift_proto.db.lock.db
削除してみてください：
user@machine:~/folder$ sudo rm lift_proto.db.lock.db
何の反応もありません：
user@machine:~/folder$ ls
lift_proto.db.lock.db
私は見たその質問、しかしあまり役に立ちません。
user@machine:~/folder$ lsattr
-----------------e- ./lift_proto.db.lock.db
userまた、ファイルの所有権と権限を777に変更しようとしましたが、ファイルを削除しましたが、まだルート所有権と以前の権限に戻りました。
私の最後の推測は、誰かが何とか他の場所でファイルを同期したことです（しかしそれを見る方法はありますか？）。そうでない場合（たとえば、属性などがあるものがあることがわかります）、どのように削除しますか？

ファイルは水素2ファイルロック、次から昇降機（Web）ベースのアプリケーション。 H2は興味深いものを使いますファイルロックプロトコル、データベースが使用中の場合、ファイルは直ちに再生成されます。
（ファイル名はフレームワークのデフォルト永続性データベース名と一致します。）
このファイルを削除するには、このデータベースを実行しているすべてのアプリケーションサーバーを停止する必要があります。 （しかし本当に？）
出力straceには、切断が成功したことが明確に表示されます。
