[Liu, ZhipengS]

Hi Boxiang and all,

In fetch_to_raw(),
After force convert image from qcow2 to raw,  the format is still not raw,  then throw below error.
It seems qemu-image convert image failed.

Hi Boxiang,

It should be an issue in nova train.
Error log is below:
build of instance 363dddce-7af6-4701-8cea-52630b91ebcf aborted: Image 70f74018-24f6-4d7d-8f99-2194a4449cfd is unacceptable: Converted to raw, but format is now qcow2'

You tried to fix this issue before in nova LP:
https://bugs.launchpad.net/nova/+bug/1816686
In your patch: https://review.opendev.org/#/c/640271 (This patch is already in train release now)
You added below commit message in the patch.

“When we import image into rbd, check the format of cache
images. If the format is not raw, remove it first and
fetch it again. It will be raw format now.”

However, it seems not work!  Below code will throw error when image format is not raw and block the VM creation.

In nova/virt/images.py
def fetch_to_raw()  ==>
if data.file_format != "raw":
                      raise exception.ImageUnacceptable(image_id=image_href,
                        reason=_("Converted to raw, but format is now %s")

Not sure if your patch fixed this issue or is there any regression introduced in nova code later.
Any comment from you?
I will check nova code further tomorrow and sync with you.
We may need a patch for nova☹

Thanks!

Hi Zhipeng,

The results are OK for Simplex, Duplex and Standard Local Storage, all Test Cases PASSED.

For Standard External Storage (2+2+2) there is a high quantity of Test Cases failing because we cannot launch instances. Here’s a sample output: http://paste.openstack.org/show/785641/ with the error that matches what is described on the launchpad.

Sanity summary for this specific configuration: http://paste.openstack.org/show/785655/

Please, let us know if you need additional details.

Thanks & Regards,

Cristopher Lemus
