다음같은 에러로그가 찍히며 prometheus 실행이 안될 경우
에러문에 찍힌 말처럼 "opening storage failed: found unsequential head chunk files /data/prometheus/prometheus/chunks_head/000009 (index: 9) "
./prometheus/data 디렉토리 안에 lock 파일이 동시성 문제가 발생하지 않게 하기위한 파일인데 비정상 종료로 인해 삭제되지 않고 남아있게됨으로써 발생하는 문제입니다.

이 경우 prometheus를 내린다음 ./prometheus/data 디렉토리 안에 lock파일을 삭제 후 prometheus를 재실행 하면 됩니다.
