개요
개별 동작에 따라 발생하는 일련의 로그 패턴들에 대해 분석하고 설명합니다.
동작
| Info |
|---|
windwos bsr 1.6.1 버전의 로그를 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. 기동 시점의 로그 시간을 보면 시스템이 시작한 시간을 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.
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.
