ceph) osd 초기화시키_TYPE="ceph_bluestore" 초기화

 

rook-ceph연습하다가 osd 추가 삭제 연습을 하고 있었어요

그런데 osd가 자동 매핑되려면, 비어있어야하는데

기존 데이터와 서명이 남아있어서 문제가 생겼어요

 

skipping device "sdc" because it contains a filesystem "LVM2_member".

초기화 시키고 나서 rook-ceph operator를 초기화시켜주니 알아서 매핑을 했습니다.

$ k rollout restart deployment.apps/rook-ceph-operator -n rook-ceph
