Are you sure this is reproducible in pure nova code? Because this looks
like forked nova code for starlingx:
Traceback (most recent call last):
File
"/usr/lib64/python2.7/site-packages/nfv_plugins/nfvi_plugins/nfvi_compute_api.py",
line 2127, in resize_instance
future.result = (yield)
Looking at this code in the compute API in pure nova, it looks like that
error only gets raised here:
https://github.com/openstack/nova/blob/e25d59078e61fe9f925dbef53dfe88e575d34dab/nova/compute/api.py#L655
Which is being called from resize now:
https://github.com/openstack/nova/blob/e25d59078e61fe9f925dbef53dfe88e575d34dab/nova/compute/api.py#L3652
As a result of this change in stein:
https://review.openstack.org/#/c/620706/
Note that root_bdm=None there so that's how we get into the else block
of _validate_flavor_image_nostatus because it's not considering the
instance as volume-backed.

Bug description:
Brief Description
-----------------
resize of instance, that was booted from volume, trigger image size check
then fails resize
Severity
--------
standard
Steps to Reproduce
------------------
1. Create two flavors based on originating flavor and destination
flavor
| 15566866-06d7-487a-b087-9fe928ec8c00 | flavor | 1024
| 4 | 0 | | 1 | 1.0 | True
flavor:extra_specs | {"stx_storage": "remote",
"hw:mem_page_size": "2048"}
flavor:ram | 1024
|
| flavor:swap | 0
|
| flavor:vcpus | 1
| flavor:disk | 4
|
| flavor:ephemeral | 0
| 20ebe3fe-c1a3-4e62-8c34-10c435f27112 | flavor-2 | 1024 | 1 | 1
| 512 | 1 | 1.0 | True
| extra_specs | {"stx_storage": "remote", "hw:mem_page_size":
"2048"}
name | flavor-2
| ram | 1024
| swap | 512
| vcpus | 1
| disk | 1
2. Boot instance from volume with an originating flavor
OS-EXT-SRV-ATTR:hostname | tenant2-vm-13
id | 04f43c9e-d3fa-46c4-9605-c0d1cf8dda71
os-extended-volumes:volumes_attached | [{"id":
"672aaa60-1086-45ce-8650-8195aa8dd0da", "delete_on_termination": false}
OS-EXT-SRV-ATTR:hypervisor_hostname | compute-0
OS-EXT-SRV-ATTR:instance_name | instance-000000a4
3. Resize instance to destination flavor that has smaller disk size.
Confirm resize.

20ebe3fe-c1a3-4e62-8c34-10c435f27112'
Expected Behavior
------------------
Did not expect resize of instance, that was booted from volume, to trigger
image size check
Actual Behavior
----------------
[2019-04-14 10:05:06,427]
Resize of instance booted from volume inadvertently triggered the image size
check and results in a ClientExpection related to FlavorDiskSmalerThanMinDisk
ERROR (ClientException): Unexpected API Error. Please report this at
http://bugs.launchpad.net/nova/ and attach the Nova API log if possible.
