Openstack dashboard Error: Unable to retrieve usage information, instances
Openstack dashboard Error: Unable to retrieve usage information, instances
我在 Ubuntu 16.04 LTS（安装在 VirtualBox 中）上安装了 devStack
当我登录仪表板时出现此错误（在概览 选项卡中）：
Error: Unable to retrieve usage information
我尝试了我在网上找到的解决方案，但没有一个有效（其中很多已被弃用，没有 解决方案中提出的 ./rejoin-stack）
同样的问题，当我按 Instances 我得到：
Error: Unable to retrieve instances.
对于卷选项卡：
Error: Unable to retrieve volume list.
Error: Unable to retrieve snapshot list.
对于图片 选项卡：
Error: Unable to retrieve images.
在图像 选项卡中：
Error: Unable to retrieve security groups.
Error: Unable to retrieve key pair list.
Error: Unable to retrieve floating IP addresses.
Error: Unable to retrieve floating IP pools.
这是我第一次安装devStack，我不知道去哪里查看！
我编辑了存在于 devstack/samples 中的 local.conf 文件，这里是文件的内容：
# Sample ``local.conf`` for user-configurable variables in ``stack.sh``
# NOTE: Copy this file to the root DevStack directory for it to work properly.
# ``local.conf`` is a user-maintained settings file that is sourced from ``stackrc``.
# This gives it the ability to override any variables set in ``stackrc``.
# Also, most of the settings in ``stack.sh`` are written to only be set if no
# value has already been set; this lets ``local.conf`` effectively override the
# default values.
# This is a collection of some of the settings we have found to be useful
# in our DevStack development environments. Additional settings are described
# in http://devstack.org/local.conf.html
# These should be considered as samples and are unsupported DevStack code.
# The ``localrc`` section replaces the old ``localrc`` configuration file.

No rejoin-stack.sh script in my setup
这意味着 devstack 在重启后不应该工作
在新版本的devstack中，rejoin-stack.sh已被删除。
您可以使用 screen -c stack-screenrc.
