ceph的块存储太简单了。所以不做演示

查看集群

创建一个 CephFS 文件系统
# ceph fs volume create cephfs01
需要创建一个子卷# ceph fs subvolume create cephfs01 my-subvol
-----------------#以下全部自动创建好
# ceph fs ls       
name: cephfs01, metadata pool: cephfs.cephfs01.meta, data pools: [cephfs.cephfs01.data ]# ceph osd pool ls
.mgr
cephfs.cephfs01.meta
cephfs.cephfs01.data

最后配置K8S yaml即可

helm repo add ceph-csi https://ceph.github.io/csi-charts
helm install -n ceph-csi ceph-csi-cephfs ceph-csi-cephfs-3.13.1.tgz -f values.yaml

以下我的yaml参考

# egrep -v "^[[:space:]]*#|^$" values.yaml
