redis-server - Redis が次のエラーで起動に失敗する: redis-server.service: Failed at step NAMESPACE spawning /usr/bin/redis-server: Stale file handle

Question

Debian をアップグレードした後、起動時に問題が発生しredis-server.serviceます。の出力journalctl -xeには、次のように表示されます。

redis-server.service: Failed at step NAMESPACE spawning /usr/bin/redis-server: Stale file handle.

redis-server.service を開始できず、の出力に次のように表示systemctl start redis-serverされます。

Job for redis-server.service failed because the control process exited with error code.
See "systemctl status redis-server.service" and "journalctl -xe" for details.

私が持っているの出力でsystemctl status redis-server：

● redis-server.service - Advanced key-value store

この問題を修正して redis-server.service を開始する方法を教えてください。
