Question

我尝试在Ubuntu 12.04上使用devstack连接Hyper-V中的nova-compute，但出现此错误：

数据库中的实例表中缺少一列。

代码可能已过时;此命令将更新DB：

nova-manage db sync

如果代码超级过时，该命令可能无法正常运行，您可以向后同步，然后向前同步：

首先找到最早的版本：

ls nova / db / sqlalchemy / migrate_repo / versions | sort -n |头
然后同步到该版本：

nova-manage db sync 112＃如果112是列表中最早的
然后再次向前同步到最后：

nova-manage db sync

如果这不起作用，您可以进入mysql并手动添加列：

alter table instances add column server_name varchar;

最后你可以删除数据库，重新创建它，然后执行同步（在mysql中）：

drop database nova;
create database nova;
grant all on nova.* to openstack@localhost identified by 'openstack';

假设您的nova db用户名+密码是openstack和openstack。（你可以从devstack localrc）

当我扩展到更多计算主机时，我遇到了完全相同的问题，而我正在排除问题我发现我有不同的nova服务版本，我添加了正确的存储库并删除了当前的Openstack计算和网络服务，安装并重新配置它们，一切都很顺利。

我正在使用哈瓦那并添加了以下存储库。（我在所有机器上都使用Centos）

yum install http://repos.fedorapeople.org/repos/openstack/openstack-havana/rdo-release-havana-6.noarch.rpm

yum install http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
