스마일 서브ceph 구성중 osd를 재구성하기 위해 설치하는 중 다음과 같은 오류가 발생할 수 있다.
다음의 오류 배경은 기존에 사용하던 osd의 raid 구성을 초기화 한후 raid 재구성시 나올 수 있는 error 메시지.
결론 부터 말하자면 osd 서버를 리부팅 해주어야 하다.
ceph의 구성 팜에 재구성 하기 이전의 osd 의 디스크 정보로 인하여 새로 재구성된 osd disk 에 대해 충돌을 일이키는 것으로 파악된다.( 오류 메시지중 일부 “You should reboot now before making further changes.”)

해당 osd 리부팅 후 osd 추가 과정인 ceph-deploy disk zpa [hostname]:[장치] 를 다시 한번 진행 해보길 바란다.
