Cypress EN 노드를 운영하던 중에 data volume이 가득 차서 노드가 며칠 멈췄었고, 볼륨 증설 후 sync에 문제가 생겨 문의 드립니다.

Regenerated local transaction journal transactions=0 accounts=0 라는 로그가 1시간에 1번씩만 찍히고, 그 이상의 진척이 없어보입니다.

이런 로그가 나오는데, 어떻게 해결을 해야하나요?

2

ken binary 버전이 어떻게 되시나요?

추가적으로 볼륨 증설 후 방화벽에서 32323, 32324 포트를 막아놓으셨는지 확인가능할까요?

3

ken version은 1.9.0이고,
inbound는 32323 - 32324 0.0.0/0으로 다 열려 있습니다.

4

다른쪽 더 봐야할 부분은 없을까요? 노드가 계속 멈춰있는 상태라서요…

5

현재 로그로는 다른 노드와 연결이 되지 않은 것으로 보입니다. admin.peers 명령어를 통해 연결된 노드가 있는지 확인하실 수 있습니다.

다른 노드와 연결이 안된 이유는 지금 정보로는 파악하기 힘들지만, 기존과 동일한 환경이라면 네트워크 설정의 문제는 아닐 것으로 보입니다. 우선, 직접 PN 정보를 입력하여 static하게 peer 연결을 시도해 보는 것도 한 방법입니다.

아래 링크를 참조해서 특정 PN에게 직접 연결을 시도해보시는 것도 좋을 것 같습니다.

아 네네. peer 의 문제였네요. addPeer로 해결했습니다. 감사합니다.
