OpenStack volume quota设置

操作环境：

OpenStack Icehouse

在cinder创建volume的时候，提示因为quota限额，无法创建

[root@ceph-osd-1 ~]# cinder create --display-name osd5 150                                                                                                ERROR: VolumeSizeExceedsAvailableQuota: Requested volume or snapshot exceeds allowed Gigabytes quota. Requested 150G, quota is 1000G and 950G has been consumed. (HTTP 413) (Request-ID: req-68783d25-0f66-4071-8b5e-ac69a3108755)
