我正在尝试在4节点堆栈上安装和配置OpenStack Mitaka。1个控制器、1个计算、1个块存储、1个对象存储。当尝试创建块存储节点时，我无法通过仪表板创建卷。基础操作系统是Ubuntu 14.04，就像我之前说的，是Mitaka发布的OpenStack。
这是控制节点上的cinder.conf

创建卷后状态为"error"。这里是我在cinder-scheduler.log文件中得到的错误行Controller Node
2016-09-07 17:14:22.291 10607 ERROR cinder.scheduler.flows.create_volume [req-272c5387-a2e3-4371-8a14-8330831910d0 a43909277cbb418fa12fab4d22e0586c 64d180e39e2345ac9bbcd0c389b0a7c4 - - -] Failed to run task cinder.scheduler.flows.create_volume.ScheduleCreateVolumeTask;volume:create: No valid host was found. No weighed hosts available
我认为这是错误信息中最重要的部分:
volume:create: No valid host was found。没有主机可用
当我从控制节点运行命令"cinder service-list"时，我得到以下输出:
+------------------+------------+------+---------+-------+----------------------------+-----------------+

有趣的是，主机名为cinder。在Mitaka安装指南中，主机名是block1@lvm。不知道为什么我的不一样，或者这是否相关。发现它很有趣，也许是我问题的线索。
这让我相信Cinder Node和Controller Node能够"看到"或相互通信。我相信我已经在Cinder节点中正确配置了lvm。为了以防万一，下面是lvm.com .conf文件中的过滤器部分:
filter = [ "a/sda/", "a ...
说了这么多。我认为这是一个分区/硬盘格式的问题。或者，rabbitmq(消息服务)问题。我确实有rabbitmq-server安装在Cinder Node上，我知道这不是指南设置的方式，这意味着它可能是错误的。我现在要做的是从Cinder Node中删除rabbitmq-server。我相信我会遇到的问题是，Cinder Node和Controller Node不会"看到"对方。如果是这样的话，那么我现在运行的3个节点中的任何一个上的cons文件可能有问题?当前运行的3个节点分别是Controller、Compute和Cinder。
让我知道你们的想法。如果你看到我的文件有问题，请告诉我。最后一段是解释我的想法，以及项目的现状。如果你看到我的逻辑错误，或者认为可能有更好的方法来解决问题，我洗耳恭听!
谢谢大家!
首先检查vgs命令的输出。如果你安装了openstack(和我一样)通过packstack。默认的卷大小是20GB左右。您可以查看packstack应答文件来确认或查看卷组大小
CONFIG_CINDER_VOLUMES_SIZE = 20 g
如果你想扩展这个卷组的大小，使用这个链接:-
希望这将解决您的问题。
您将enabled_backends键放在了错误的部分。它将在控制器和存储节点的[Default]部分中定义。
