我在控制器和计算节点上完成 nova 安装后，按照产品文档“https://docs.openstack.org/nova/2023.1/install/verify.html”操作，在验证安装并执行命令“nova-status upgrade check”时看到“没有这样的表：cell_mappings”。
~# nova-status upgrade check

Error:

但是当我使用 su 命令执行时，它起作用了。
:~# su -s /bin/sh -c "nova-status upgrade check" nova

不确定这是否真的是个问题。我正在 Ubuntu 22.04 jammy 上安装 OpenStack zed。
我提到了 bughttps://bugs.launchpad.net/nova/+bug/1781573但这个问题在 zed 版本中得到了解决。不确定它是否相同或不同
