openstack cinder:volume:create:找不到有效的主机。没有可用的称重主机

我正试图在我们的一个开发服务器中获得一个工作的openstack自由,这个服务器具有最小的配置并且具有ubuntu 14:04。

所有组件看起来都很好,我也能够创建实例并查看仪表板。

现在,我正在尝试创建一个卷,这是我遇到问题的地方。

我们的节点有一个磁盘' sda' 8GB,我们按照此处列出的步骤准备磁盘。 https://eatpeppershothot.blogspot.sg/2016/04/use-real-block-storage-backend-for.html

输出lsblk

名称FSTYPE LABEL MOUNTPOINT

sda xfs

└─sda1LVM2_member

然后我们遵循标准文档 http://docs.openstack.org/liberty/install-guide-ubuntu/cinder-storage-install.html

在Controller节点上

**root@dev-controller:~/scripts# cinder service-list**
+------------------+----------------+----------+---------+-------+----------------------------+-----------------+

+------------------+----------------+----------+---------+-------+----------------------------+-----------------+

默认情况下,所有卷都列在" nova"区域,但我们在尝试时将其更改为不同的节点。

创建卷的命令 cinder create --volume_type lvm --display_name testvol 1 --availability-zone dev-osd2 cinder create --volume_type lvm --display_name testb 1

' cinder create'命令有效,但是“cinder list'命令显示卷处于错误状态。 这两个命令都以错误状态结束。

我已检查并确保所有数据库连接字符串都正确,并且主机能够连接到控制器。 RabbitMQ也很好。

请帮我解决这个问题:)

我们已经将cinder与ceph集成在一起,我们必须将ceph密钥添加到我们以前没有做过的所有计算节点。一旦我们这样做了,它运作良好
