Bug: Changing flavor causes "resize loop" on Openstack

[pasettifabio]

Hi, I'm using Crossplane's OpenStack provider to deploy instances and manage them.

Everything works very well but when I change the flavor (flavorName or flavorId) for instance, it loops through infinite resizing between the original flavor and the new one and again to the original (of course, reducing the size if the original flavor is smaller then the newest...).

This is the instanceV2 manifest:

apiVersion: compute.openstack.crossplane.io/v1alpha1
kind: InstanceV2
metadata:
  annotations:
    meta.upbound.io/crossplane01-id: compute/v1alpha1/instancev2
  labels:
    testing.upbound.io/crossplane01-name: node01-test
  name: node01-test
spec:
  providerConfigRef:
    name: openstack-cloudfire-devops
  deletionPolicy: Delete
  forProvider:
    blockDevice:
    - bootIndex: 0
      deleteOnTermination: true
      destinationType: volume
      deviceType:  
      diskBus: ""
      guestFormat: ext4 
      multiattach: false
      sourceType: image 
      uuid: "6f971b3f-7b26-4161-a4a6-9081bbad9667"

      volumeType: Standard
    configDrive: true 
    flavorId: "6c1f1ce7-f356-4dac-b02c-a9b78e9d6d07"

    metadata:

    network:

      fixedIpV4: "" 
      fixedIpV6: ""
      floatingIp: ""
      name: private
      port: "" 
      uuid: "" 
    powerState: "active" # active, shutoff, shelved_offloaded

    tags:
    - "instance"
    vendorOptions:

        ignoreResizeConfirmation: true

Here you can find the resize loop into Openstack:

Does anybody experience the same issue?

Thank you, Fabio

I am also experiencing the same behaviour/bug.

Same here.

Hello guys, I'm glad to read that I'm not the only one who experienced the issue :)

I'm not able to understand which part of the codebase is involved in this behavior, I suppose something related to the duplication of the desired state into ETCD.. do you agree or do you have any hypothesis?

Thanks

Fabio

Hi @pasettifabio try it with ignoreResizeConfirmation

[pasettifabio]

Yes, I tried with ignoreResizeConfirmation and without..
