1. 查看ceph版本

bash 复制代码

kubectl exec -it rook-ceph-tools-xxxxx -n rook-ceph /bin/bash
ceph version
# ceph version 17.2.5 (98318ae89f1a893a6ded3a640405cdbb33e08757) quincy (stable)

打开之前下载的rook-ceph文件夹（前提是你的文件夹名字已经标注了版本）在 deploy/examples/cluster.yaml里有

image: quay.io/ceph/ceph:v17.2.5

2. 删除osd

进入tool pod

bash 复制代码

# Step 1: Mark OSD as out
ceph osd out osd.3

# Step 2: Check the cluster status and wait for rebalancing
ceph -s

# Step 3: Once the cluster is balanced, remove the OSD from the CRUSH map and authentication
ceph osd crush remove osd.3
ceph auth del osd.3
ceph osd rm osd.3

# Step 4: Delete the corresponding Rook OSD deployment
kubectl -n rook-ceph delete deployment rook-ceph-osd-3 # 注意这里是deployment

# Optional Step 5: If using PVC, delete the corresponding PVC
kubectl -n rook-ceph delete pvc <pvc-name>

3. 释放出空间

需要删除 pv pvc sc,还有pool 才能释放出来

4. iscsi rook-ceph 在ceph 笔记2 中用ceph 16实现的

进入tool

ceph mgr module enable rook

bash-4.4$ ceph orch ps

Error ENOENT: No orchestrator configured (try ceph orch set backend)

bash-4.4$ ceph orch ls

Error ENOENT: No orchestrator configured (try ceph orch set backend)

bash-4.4$ ceph orch set backend rook

bash-4.4$ ceph orch ls
