谢谢各位赐教，我们可以一起讨论

两个报的同一个错误 /etc/sudoers is owned by uid 1000
uid 0是用户根uid。
uid 1000应该是你自己的用户的uid。

你试一下下面的命令

%su
%"root pass"
%chown -R root:wheel /etc/sudoers
复制代码

你可以看一下sudoers文件的作用。
sudo为系统管理员提供配置文件，允许系统管理员集中地管理用户的使用权限和使用的主机。它默认的存放位置是/etc/sudoers。 你尝试给他们授权，让你当前的用户，能够读取sudoers文件

chown root:root /etc/sudoers 
chmod 440 /etc/sudoers
chown -R root:root /etc/sudoers.d
chmod  755 /etc/sudoers.d 
chmod  440 /etc/sudoers.d/*
复制代码

恩恩，我试试

试一下下面两种方法，用其中一种就可以：
创建一个名字为 nova-volumes 的卷组，方法有两种：
(1).服务器上没有单独的分区的时候，使用img文件来做卷组
dd if=/dev/zero of=/opt/nova-volumes.img bs=1M seek=100000 count=0
losetup -f nova-volumes.img
vgcreate nova-volumes /dev/loop0
(2).服务器上有单独的分区，如：/dev/sdb2
vgcreate nova-volumes/dev/sdb2

虽然问题还是哪个。但是，还是感谢楼主把我的问题看做是自己的问题来认真、细心的整。感谢楼主了。
有时间，再问看吧

第一个问题应该解决了吧

没有呢，还是有那两个问题。

第一个是没有错的，你检查是不是自己的方法或则实现方面有没有问题。
