supermathie · 1월 16, 2026, 3:53오후

이전에 이렇게 해 본 적이 있나요?

marianord · 1월 16, 2026, 3:56오후

네, 12월 중순까지는 잘 작동했습니다.

supermathie · 1월 16, 2026, 4:17오후

업그레이드 이후에 작동이 멈췄다면, 마지막으로 정상적으로 작동하던 버전을 아시나요? (마지막으로 성공적으로 생성된 백업 파일의 파일명을 알면 도움이 됩니다.) 그리고 현재 사용 중인 버전은 무엇인가요?

marianord · 1월 16, 2026, 4:22오후

구글 파일을 찾아볼게요. 정리하던 중 확인도 전에 삭제해 버렸네요 .

v20251209012613는 이미 실패하고 있다는 건 알고 있어요. 언제부터 작동이 멈췄는지 확인하려고 더 오래된 파일들을 복구해 볼 거예요.

bondero · 2월 27, 2026, 11:24오후

저는 방금 신규 설치 환경에서 backblaze를 정상적으로 작동시켰습니다. 그리고 확인해 보니, 사용 중인 discourse 버전이 좀 오래된 것 같습니다. 스택 트레이스에 표시된 ruby 버전은 3.3.0인데, 제 환경에서는 3.4.0입니다. aws-sdk-core와 aws-sdk-s3 제모의 버전은 같은 것 같아서 차이가 있지는 않을 수도 있지만, 참고할 만한 사항이라 말씀드립니다.

다시 시도해 보았지만 동일한 오류가 발생했습니다.

네, 제 환경에는 AWS_*_CHECKSUM_CALCULATION 설정이 없어서, 해당 설정 때문에 에러가 나는 것 같습니다. B2가 이 기능을 지원하지 않는다는 스레드가 있는데, 최근 이 기능이 구현된 것 같지만 실제로 동작하는지는 확실하지 않습니다.

marianord · 3월 4, 2026, 2:07오후

음, 그게 통했네요.

완료!
