개요

개별 동작에 따라 발생하는 일련의 로그 패턴들에 대해 분석하고 설명합니다.

동작

Info

windwos bsr 1.6.1 설치 및 1:1 연결의 주요 동작 로그로 작성되었습니다.

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

동작

커널 로드

windows 에서 bsr 커널 드라이버는 시스템 시작 시 로드되며 로드 시 출력 되는 로그입니다.

...

버전의 로그를 기준으로 합니다.

드라이버 기동

다음은 windows 에서 bsr 커널 드라이버가 기동할 때의 로그 입니다.

드라이버 버전과 드라이버에서 사용하는 port 정보등을 출력합니다.
- 시스템 로그가 없는 상황에서는 커널 로드 로그 출력 시간을 통해 시스템 시작 시간을 짐작하기도 합니다윈도우즈 커널 드라이버는 시스템이 시작하는 시점에 기동합니다. 기동 시점의 로그 시간을 보면 시스템이 시작한 시간을 유추할 수 있습니다.

명령 실행

bsradm.exe, bsrsetup.exe, bsrmeta.exe, bsrcon.exe 으로 명령 실행 시 bsr 커널에서 실행되는 명령의 경우 bsr 커널 명령 실행 전 실행 후 로그를 출력합니다.
- 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 작성했으며 다른 주요 동작 로그에서 작성하고 설명합니다.

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.

Netlink 를 통한 유틸리티 명령은 커널로그로 기록되며 명령의 시작과 끝은 인식할 수 있도록 아래의 로그와 같이 기록하고 있습니다.
- 명령의 시작은 command has been received. Execute the command. 로 기록됩니다.
- 명령의 끝은 command execution terminated. 로 기록됩니다.
- 명령의 시작과 끝을 하나의 쌍으로 보고 하나의 명령단위로 간주하면 됩니다.
다음의 로그 예는 Netlink 명령의 시작과 끝 로그 만을 중점으로 기록한 내용입니다. 시작과 끝 사이에 명령을 수행한 내역의 로그들은 가독성을 위해 생략하였습니다.

상태 변경

bsr 커널은 disk, peer disk, replication, connection, role 상태 변경 시 로그를 출력합니다.
- 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.

connect 명령 실행

bsradm, bsrsetup 으로 connect 명령 실행 시 연결되는 과정의 로그를 출력합니다.
- connect 명령은 연결 가능한 상태로 변경 후 완료됩니다.
- 시스템 또는 네트워크 상황등으로 연결 종료 시 자동으로 연결되며 이때도 connect 명령 실행과 동일한 과정의 로그가 출력됩니다.
