NFS 마운트 명령이 서버 재부팅 후 클라이언트에서 무기한 중단됩니다.
이 명령을 실행 중입니다.mount -t nfs -v 10.17.25.27:/DATA/projects/assets-db/log-apache test
내 NFS 서버는 : 10.17.25.27, 클라이언트 IP는10.17.25.152
nfs에 대해 syslog 디버그를 활성화했는데 다음 오류가 표시됩니다.

NFS 버전 3으로 마운트하면 작동하지만 버전 4의 기능이 필요하므로 이 이전 버전의 프로토콜로 다운그레이드할 수 없습니다.
나는 CentOS 7.2커널을 사용 하고 있습니다3.10.0-514.26.2.el7.x86_64
답변1
NFS가 갑자기 다운된 이유를 찾지 못했고 다시 시작한 후 클라이언트가 내보낸 파일 시스템을 마운트할 수 없었습니다. 우리는 모든 서버를 다시 시작하고 시스템 사이의 모든 포트를 열려고 시도했지만 아무 것도 성공하지 못했습니다.
3.10.0-514.26.2.el7.x86_64하지만 커널을 버전에서 다음 버전 으로 업그레이드한 후에 다시 작동하게 만들 수 있었습니다.3.10.0-862.11.6.el7.x86_64
