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.

Verbosity를 5로 높혀 찍으니

이런 로그가 나오는데, 어떻게 해결을 해야하나요?

ken binary 버전이 어떻게 되시나요?

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

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

다른쪽 더 봐야할 부분은 없을까요? 노드가 계속 멈춰있는 상태라서요…

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.

> 방화벽 등에서 32323, 32324 포트를 막거나 하는 변경은 없으셨던거죠? 저희쪽에서 이슈가 재현되지 않아 당장 원인을 파악하는데는 시간이 조금 걸릴거 같네요. 우선은 직면한 이슈를 해결하기 위해 아래 명령어를 통해 static 하게 PN과 연결하는 방안을 권장드립니다. // statically connect to a PN admin.addPeer("kni://772b3b5ed369641d5812ff0872785e2decd9161cf168855c16805b87bfc4bca7872f597dc1ca7c17f69dcbe6aaa84e48353e9c1a48b60af5440606298df5fdf9@52.79.95.186:32323?ntype=pn") // statically connect to another PN admin.addPeer("kni://81c44374fe0ff0ab1193b05bea30ffcb36bd976cf4e251b209ccf198e1436c90894f4e8e69…

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