问题描述
我正在尝试将卷附加到图像。我的尝试始终失败。
我正在使用以下命令创建附件：
openstack server add volume test_instance testvol
其中test_instance是我的实例，而testvol是我用Cinder创建的20G卷。
尝试该附件时没有收到任何错误消息，但是当我检查卷时却看不到附件：
cinder list
+--------------------------------------+-----------+-------------+------+-------------+----------+-------------+
| ID | Status | Name | Size | Volume Type | Bootable | Attached to |
+--------------------------------------+-----------+-------------+------+-------------+----------+-------------+
| 3dce2112-eddc-4d39-b47d-8717b16dd5e9 | available | testvol | 20 | __DEFAULT__ | false | |
| a9aa8845-dd3a-4f47-8b5e-445c6170abbe | available | volume1 | 20 | iscsi | false | |
+--------------------------------------+-----------+-------------+------+-------------+----------+-------------+
我没有看到附件。以上是我尝试连接testvol或volume1时得到的信息。
查看nova-compute日志，我收到以下消息：
