openstack--Build of instance aborted: Volume resource quota exceeded
前言
创建虚拟机出错，报错日志如下
2020-02-17 14:30:04.667 17107 WARNING nova.compute.manager [req-c2eab55a-7588-4191-9a97-eaac21b16553 ee34dd53da7b4ceaa62f0c2667edb4d6 921ac80ffd364fc0b347ecc4e68ba5c5 - - -] [instance: 5f02407d-c620-45f4-9015-54c0ebc13393] Failed to create block device for instance due to being over volume resource quota

这是由于卷volume的数量超过配额引起的，之前创建了不少volume作为存储端的虚拟机，删除了虚拟机，但是volume没有删除。

用命令行查看确实有很多僵尸卷。
解决的办法是从volume启动虚拟机时，加上shutdown=remove的参数，这样删除虚拟机时，默认也删除卷。

可以看到"delete_on_termination": true，删除虚拟机时，卷也会删除。
