storage: # cluster level storage configuration and selection
#如果为FALSE，可以踢出问题node，否则不行	useAllNodes: true
	useAllDevices: false

nodes:
	# - name: "172.17.4.101"

指定ceph存储路径 lvm可以扩展

nodes:
- name: "hostname1"
directories: # specific directories to use for storage can be specified for each node
- path: "/home/data/ceph"
- name: "hostname2"
directories: # specific directories to use for storage can be specified for each node
- path: "/home/data/ceph"
