我正在尝试将卷附加到图像。我的尝试总是失败。
我正在使用以下命令来创建附件：
openstack server add volume test_instance testvol
其中 test_instance 是我的实例，testvol 是我使用 Cinder 创建的 20G 卷。
尝试此附件时，我没有收到任何错误消息，但是当我检查我的音量时，我没有看到附件：
cinder list
+--------------------------------------+-----------+-------------+------+-------------+----------+-------------+
| ID | Status | Name | Size | Volume Type | Bootable | Attached to |
+--------------------------------------+-----------+-------------+------+-------------+----------+-------------+

+--------------------------------------+-----------+-------------+------+-------------+----------+-------------+
我看没有附件。以上是我尝试附加 testvol 或 volume1 时得到的结果。
查看 nova-compute 日志，我收到以下消息：
