Title:
Nova is not updating IOPS configuration if you perform a volume resize
on cinder
Status in OpenStack Compute (nova):
Expired
Bug description:
===========
When you use cinder volume-type to limit iops on the frontend work as expected when you create a instance however if you resize the volume the IOPS limit is not updating on the instance.
Steps to reproduce
==================
1.Create a Volume-type with Associated QoS Spec
2.Create a Qos Spec with frontend and specs total_iops_sec_per_gb=3
3.associate this QoS to Volume Type
4.Create a new instance with a 100GB volume these new volume type you will notice in KVM the following configuration.
<iotune>
<total_iops_sec>300</total_iops_sec>
</iotune>
5.stop the instance
6.cinder extend <Volume> 300
7.start the instance
Expected result
===============
After the instance is started KVM should update the total_iops_sec to <total_iops_sec>900</total_iops_sec>
Actual result
=============
the total_iops_sec keeps with the original configuration when the computer was provisioned.
Environment
===========
1.Openstack Train
2.KVM
2. NFS
