redis-py - MISCONF Redis is configured to save RDB snapshots, ...

어느 순간, 테스트 서버에서 호스팅 중인 컨테이너에서 각종 오류들이 쏟아졌습니다. ^^; 가령, redis 호출에 대해서는 이런 오류 메시지가 나오고,

Traceback (most recent call last):

redis.exceptions.ResponseError: MISCONF Redis is configured to save RDB snapshots, but it is currently not able to persist on disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.

Mongo DB 호출은 이렇게 나오고,

MySQL 서버 호출은 이런 오류가 발생합니다.

Traceback (most recent call last):
  File "/home/testusr/.local/lib/python3.11/site-packages/flask/app.py", line 2190, in wsgi_app
    response = self.full_dispatch_request()

  File "/home/testusr/.local/lib/python3.11/site-packages/flask/app.py", line 1801, in make_response
    raise TypeError(
TypeError: The view function for 'main.mysqlclient_wrapper2' did not return a valid response. The function either returned None or ended without a return statement.

당황하지 마시고, 컨테이너를 호스팅하는 서버의 디스크 용량을 확인해 보시고, 꽉 찼으면 여유 공간을 확보해 주시면 됩니다. (그나저나, redis의 오류 메시지가 그나마 실제 상황에 가깝군요. ^^)
