Openstack multiple cinder backend
Multiple pool backend
Ceph backend 사용시 cinder의 기본 backend pool인 volumes외에 추가 pool을 사용하고자 하는 경우 CinderRbdExtraPools 속성을 추가한다.
parameter_defaults: CephClientKey: AQDwDCdiAAAAABAACo5BC/EwTx16sAxTSzyT5Q== CephClusterFSID: 78150b72-0a47-44fd-bea0-c38af1e74077 CephExternalMonHost: 172.16.1.31, 172.16.1.32, 172.16.1.33 CephAnsiblePlaybookVerbosity: 1 CinderRbdExtraPools: hddpool,ssdpool
위와같이 추가하게 되면 hddpool, ssdpool 을 추가 volume backend로 사용할 수 있게 된다.

2가지 볼륨 서비스가 추가로 기동된것을 확인 할 수 있다.
이후 볼륨 타입을 추가해준다.
