• 部署Rook Operator

cd cluster/examples/kubernetes/ceph
kubectl create -f common.yaml
kubectl create -f operator.yaml
kubectl -n rook-ceph get pod   #验证rook-ceph-operator, rook-ceph-agent, and rook-discover是否在running

• 创建集群

kubectl create -f cluster.yaml

cluster.yaml最后nodes指定节点的相关设备

    useAllNodes: false
    useAllDevices: false
   
    - name: "192-168-60-14"
      devices: # specific devices to use for storage can be specified for each node
      - name: "sdb"
      - name: "sdc"

• 但是集群osd无法在相关设备创建，如下图

• 执行以下命令查看错误

kubectl -n rook-ceph get pod -l app=rook-ceph-osd-prepare
kubectl -n rook-ceph logs rook-ceph-osd-prepare-192-168-60-14-v7st6 provision

• **登陆到192-168-60-14去除gpt header

DISK="/dev/sdb"
sgdisk --zap-all $DISK
DISK="/dev/sdc"
sgdisk --zap-all $DISK

• 重启operator

kubectl -n rook-ceph delete pod -l app=rook-ceph-operator
这里operator会自动起一个pod，不需要担心operator

• 可见osd自动创建成功了

kubectl -n rook-ceph logs rook-ceph-osd-prepare-192-168-60-14-shkf6 provision

kubectl -n rook-ceph get pod -o wide
