개요

개별 동작에 따라 발생하는 일련의 로그 패턴들에 대해 분석하고 설명합니다.

동작

예로 든 로그 메시지들은 windwos bsr 1.6.1 버전을 기준으로 합니다.

드라이버 기동

다음은 windows 에서 bsr 커널 드라이버가 기동할 때의 로그 입니다.

  • 드라이버 버전과 드라이버에서 사용하는 port 정보등을 출력합니다.

  • 윈도우즈 커널 드라이버는 시스템이 시작하는 시점에 기동합니다. 해당 시간을 통해 시스템이 시작한 시간을 대략적으로 유추할 수 있습니다.

상태 변경

다음은 bsr 커널의 disk, peer disk, replication, connection, role의 상태가 변경될 때 발생하는 로그 입니다.

  • 복수의 상태 변경이 하나의 로그에 출력 될 수 있습니다.

  • 연결 상태가 connected 에서 connecting 또는 standalone 으로 변경 될 경우, 연결 상태 변경 로그를 중심으로 분석합니다.

  • 로그에는 해당 상태 변경을 수행한 호출자 함수의 이름이 같이 출력됩니다. 함수의 호출 흐름을 추적하여 디버깅 정보로 활용할 수 있습니다.

    • 다음 로그에서 상태 변경을 수행한 호출자는 change_disk_state, recevie_state, change_role, connect_work 가 됩니다.

Netlink 명령

다음은 bsr 유틸리티로 명령을 수행했을 때의 로그와 설명입니다.

  • 명령 실행 시 “"실행 명령" command has been received. Execute the command.”, 명령 실행 후 “"실행 명령" command execution terminated. (pending command:0)” 로그를 출력하며 실행되는 명령은 “실행 명령”으로 표시됩니다.

    • 예를들어 명령 실행 시 “"실행 명령" command has been received. Execute the command.” 은 있으나 매칭되는 “"실행 명령" command execution terminated. (pending command:0)” 이 없다면 명령이 완료되지 않은 상황임을 알 수 있습니다.

  • 명령에따라 실행 완료까지 대기 또는 대기하지 않을 수 있습니다.

  • 명령 실행으로 출력되는 로그는 “...” 으로 작성했습니다.
