在OpenStack中创建实例时遇到'实例处于错误状态'的问题，错误信息显示卷组未找到。通过查看nova和cinder的日志，定位到错误源在于卷组 'cinder-volumes' 不存在。解决方案包括检查磁盘分区和卷组，修改cinder配置文件中的volume_group名称，以及更新LVM过滤器。在调整后，实例创建成功。

openstack创建实例的时候出现报错：实例 “test-1” 执行所请求操作失败，实例处于错误状态。: 请稍后再试 [错误: Build of instance 6ec6e8b1-9300-4be4-95fe-20434ea041f5 aborted: Volume e3dcad3d-dd22-4947-99d8-b8d0ad4b1025 did not finish being created even after we waited 3 seconds or 2 attempts. And its status is error.].

第一反应以为是nova的创建实例超时时间过短导致，但是报错的时间并没有超过默认的配置。以防万一，先更改nova的配置：
[root@cinder ~]#vi /etc/nova/nova.conf
block_device_allocate_retries=300
block_device_allocate_retries_interval=5
block_device_creation_timeout=600

重启nova服务。果然还是有报错。查看nova-compute的日志：
[root@cinder ~]#tail -100f /var/log/nova/nova-compute.log

发现实例状态错误，没有完成创建。这一报错实际在页面已经显示出来了。我们继续查看cinder节点的日志：
