저는 Synology NAS에서 커널 패닉이 발생하는(또는 무슨 일이 일어나고 있다고 생각하는지) 문제를 디버깅하고 있습니다. 이런 일이 발생하면 NAS는 핑에 응답하지 않으며 이를 복구하는 유일한 방법은 전원 버튼을 10초 동안 눌러 전원을 강제로 끄는 것입니다.
무작위로 발생합니다(한 달에 몇 번에서 하루에 몇 번). 나는 고객 서비스와 협력했으며 이미 다음을 수행했습니다.
- NAS 자체를 교체했습니다. 그런데 Synology DS1815+입니다.
- RAM 모듈(내가 가지고 있는 확장 RAM)을 교체했습니다.
커널 패닉이 여전히 발생하는 것 같고 드라이브 중 하나가 원인일 것으로 의심되기 시작합니다. 패닉을 인식하는 사람이 있습니까?
