我在 CentOS 8 中使用 openstack-victoria (packstack) 来完成学校作业。我正在尝试使用我制作的 qcow2 图像创建一个实例，图像大小约为 1.9GB（CentOS 7 - 模板）。我用 30GB 的卷制作了这张图片。
创建实例后大约需要 4-5 分钟，然后我在 openstack 仪表板中收到此错误消息：
Error: Failed to perform requested operation on instance "test", the instance has an error status: Please try again later [Error: Build of instance 2b5bf737-dbd3-4173-afd0-3cb95c7d236b aborted: Volume e87171f3-99bc-4ef1-bdcc-eed55461cd18 did not finish being created even after we waited 188 seconds or 61 attempts. And its status is downloading.].
/var/log/cinder/volume.log 文件包含：
2021-03-26 15:11:35.972 3029 ERROR oslo_messaging.rpc.server cinder.exception.ImageCopyFailure: Failed to copy image to volume: qemu-img: error while writing at byte 20401094656: No space left on device
这很奇怪，因为我还有很多存储空间
控制器/计算节点 packstack.openstack.local:

注意：我也在运行 1 个计算节点，我不知道这是否重要，但这是该 VM 的 df：

我正在尝试在控制器/计算节点上创建实例。会不会是我做的qcow2图片不对？我可以毫无问题地从 cirros 图像创建一个实例，但我认为这与我尝试制作的卷的大小有关。
我尝试更改 cinder.config 文件中的“image_conversion_dir”，但这没有帮助。我还查看了iotop中发生的情况，您可以看到有一个文件写入loop1，大小约为19GB。而且我还在 iotop 中看到了一些煤渣线程：
