Nova 实例在启动时抛出错误 - “无法对实例执行请求的操作”

Question

Nova instance throws an error on launch - "failed to perform requested operation on instance….the server has either erred or is incapable of performing the requested operation (HTTP 500)". See screenshot below.

InstanceCraetion Error

Surprisingly it works well when attaching volume separately after instance launch. You need set "Create New Volume” to “No” during creation of instance.

We restarted cinder service, but it did not solve the issue.

From the API logs we figured out that there is HTTP 500 error during API interactions in service endpoints (Nova & Cinder). Logs pasted below.

Can someone help to resolve this issue ?

Thanks in advance.

Answer 1

I got the fix for this issue. I have observed there were few projects in Openstack where volume deletion stuck in error state with "Error deleting". I changed the volume state explicitly from cinder db using the "cinder reset-state --state available volume-id".

This allowed me to delete the volume successfully. I restarted the cinder service then after and everything stated working as usual
