systemd에 "networking.service failed"라고 표시되지만 네트워킹이 작동 중입니다.

평소에는 openrc init을 이용해서 젠투를 실행하는데, 데비안 10 서버를 설치하다 보니 시스템을 이해하는 데 다소 어려움을 겪습니다. 서버는 결합된 네트워크 인터페이스를 생성한 다음 iscsi 루트에서 시작하는 사용자 정의 dracut initrd로 시작됩니다. 그 부분에서는 모든 것이 잘 작동합니다. 시작 시 세 개의 인터페이스와 해당 네트워크(192.168.1.0/24, 10.0.0.0/24 및 172.16.0.0/24)가 있습니다.

내 (사소한) 문제는 systemd가 다음을 제공한다는 것입니다.

# systemctl --failed
  UNIT               LOAD   ACTIVE SUB    DESCRIPTION
● networking.service loaded failed failed Raise network interfaces

이는 주로 초기화 중에 네트워크 중 하나가 활성화되었기 때문인 것 같습니다. 젠투에서는 네트워크 서비스를 제공하지 않는 인터페이스를 표시할 수 있습니다. systemd에도 비슷한 개념이 있나요? 아니면 제가 놓친 설정이 있나요? 다시 말하지만, 모든 인터페이스가 실제로 작동하고 있습니다(브리지 2개, 본드 1개). 본드와 브리지에서 로컬 인터페이스와 NICS를 잘라냈습니다.

답변1

해결되었습니다!

/etc/network/interfaces에 두 개의 게이트웨이가 정의되어 있습니다. 하나만 빼고 모두 삭제하면 오류가 수정되었습니다.

# systemctl --failed
0 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.
