안녕하세요. Openstack을 학교 서버에 수동으로 설치 중인데, Cinder 관련 해서 문제가 발생해서 도움 요청 합니다.
Queens 버전 최소 설치 가이드 (
https://docs.openstack.org/cinder/queens/install/index-ubuntu.html)를 참고 해서
설치 중인데, 인스턴스를 생성 할 때, 해당 인스턴스가 사용할 volume을 storage server에서 못받아 오는 것 처럼
보입니다.
iSCSI를 위한 tgt 서비스를 보면, 뭔가 커널 모듈이 추가적으로 로드 되어야 하는거 같은데, 이게 스토리지 서버에 있는 RAID
controller 와 관련이 있을까요?
아래는 tgt 서비스의 상태입니다.

그리고 아래는 cinder 서비스의 상태 입니다.

Cinder-volume의 로그는 계속해서 cinder-volume 서비스가 통신을 못하고 있는 것 처럼 보이는데, 아래와 같이
volume에 접근 하려고 할 때 (e.g. instance 생성), 에러 메시지가 출력 되고, 그 이후에는 계속해서 동일한 메시지가
매초 반복되고 있습니다.

위의 로그에서 'Manage for service cinder -volume node0 at lvm is ...' 이 부분이 계속 반복 되는
부분 입니다.
혹시, 이에 대해서 경험 해 보신 분 있으시면, 조언 부탁 드립니다.
감사합니다.
