개요

동작 로그는 사용자의 bsr 커널로그 접근성을 높이기 위해 작성 되었습니다. 주요 동작에 대한 bsr 커널로그 출력과 설명을 제공합니다.

동작 로그를 읽기 위해서는 먼저 https://mantech.jira.com/wiki/spaces/BSRUG , 로그을 숙지해주세요.

동작

출력 로그는 windwos bsr 1.6.1 설치 후 1:1 연결 환경에서 수집한 로그로 작성되었습니다.

  • 작성 된 동작 로그는 성공 시 출력되는 로그이며 실패 시 다른 로그가 출력됩니다.

커널 로드

다음은 windows 에서 bsr 커널 드라이버 로드 시 출력 로그와 설명입니다.

  • bsr 드라이버 버전과 bsr 드라이버에서 사용하는 port 정보등을 출력합니다.

  • 시스템 로그가 없는 상황에서는 커널 로드 로그 출력 시간을 통해 시스템 시작 시간을 짐작하기도 합니다.

상태 변경

다음은 bsr 커널은 disk, peer disk, replication, connection, role 상태 변경 시 출력 로그와 설명입니다.

  • 복수의 상태 변경이 하나의 로그에 출력 될 수 있습니다.

  • 예상하지 못한 상태 설정 시 로그를 통해 문제 등을 유추 할 수 있습니다.

    • 예를 들어 연결 상태가 connected 에서 connecting 또는 standalone 으로 변경된다면 연결 상태 변경 로그 중심으로 원인을 분석 할 수 있습니다.

    • 로그에는 상태 변경을 진행한 함수 이름이 같이 출력되며 소스코드 확인이 가능하다면 더 상세한 분석을 할 수 있습니다.

      • 다음 로그에서 상태 변경을 진행한 함수 이름은 “change_disk_state, recevie_state, change_role, connect_work” 입니다.

명령 실행

다음은 bsradm.exe, bsrsetup.exe, bsrmeta.exe, bsrcon.exe 으로 명령 실행 시 출력 로그와 설명입니다..

  • 명령 실행 시 “bsr netlink cmd(~) begin”, 명령 실행 후 “bsr netlink cmd(~) done” 로그를 출력하며 실행되는 명령은 cmd()안에 표시됩니다.

    • 예를들어 명령 실행 시 “cmd(~) begin” 은 있으나 매칭되는 “cmd(~) done” 이 없다면 명령이 완료되지 않은 상황임을 알 수 있습니다.

  • 명령에따라 실행 완료까지 대기 또는 대기하지 않을 수 있습니다.

  • 명령 실행으로 출력되는 로그는 “..” 으로 작성했습니다.
