基于现有storageClass_yaml文件添加新的sc
方法
导出现有sc.yaml,改名，删除不必要项，apply，kg sc验证

    步骤
1.查看现有sc
需要一个新rbd_sc，名字叫csi-rbd-sc，拷贝rook-ceph-block的yaml，删改后apply
# kg sc
NAME              PROVISIONER                     RECLAIMPOLICY   VOLUMEBINDINGMODE   ALLOWVOLUMEEXPANSION   AGE
rook-ceph-block   rook-ceph.rbd.csi.ceph.com      Delete          Immediate           true                   23h
rook-cephfs       rook-ceph.cephfs.csi.ceph.com   Delete          Immediate           true                   23h

2.导出yaml
time,resource字段删掉，名字改掉就可以
# kg sc rook-ceph-block -o yaml >rook-ceph-block.yaml
    time: "2021-12-30T06:50:04Z"
  name: igo-rbd
  resourceVersion: "52083"

3.k apply -f igo-rbd.yaml
4.验证
# kg sc
NAME              PROVISIONER                     RECLAIMPOLICY   VOLUMEBINDINGMODE   ALLOWVOLUMEEXPANSION   AGE
igo-rbd           rook-ceph.rbd.csi.ceph.com      Delete          Immediate           true                   6m5s
rook-ceph-block   rook-ceph.rbd.csi.ceph.com      Delete          Immediate           true                   24h
rook-cephfs       rook-ceph.cephfs.csi.ceph.com   Delete          Immediate           true                   24h

    tips

建议k9s edit 得到的yaml比较干净直观，保存修改一样可以使用
