Verified on:
python3-glance-store-1.0.2-1.20220110223456.el8ost.noarch
On a deployment with Glance over Cinder over Netapp NFS.
Left Cinder's default raw volumes,
Using this large image:
(overcloud) [stack@undercloud-0 ~]$ qemu-img info windows_server_2012_r2_standard_eval_kvm_20170321.qcow2
image: windows_server_2012_r2_standard_eval_kvm_20170321.qcow2
file format: qcow2
virtual size: 12.2 GiB (13096714240 bytes)
disk size: 11.2 GiB
cluster_size: 65536
Format specific information:
compat: 0.10
compression type: zlib
refcount bits: 16
First attempt, lets upload to glance as a qcow2
(overcloud) [stack@undercloud-0 ~]$ glance image-create --name Windows.qcow2 --disk-format qcow2 --container-format bare --file windows_server_2012_r2_standard_eval_kvm_20170321.qcow2 --progress

Great image uploaded successfully, due to the image's large disk size of 11.2 GiB,
which is way larger than the default 1 GiB initial volume size,
we expected and as shown below on log indeed had to extend/resize the backing Cinder volume several time again and again.
Cinder volume log reports several resize cycles:

I know the bug was about uploading about qcow2,
but I already have this large source image,
lets retest with a raw source image just for fun.
qemu-img convert -f qcow2 -O raw windows_server_2012_r2_standard_eval_kvm_20170321.qcow2 windows_server_2012_r2_standard_eval_kvm_20170321.raw

Again successfully upload to Glance over cinder over netapp nfs.
As we noted above extend is no longer broken and works with both qcow2 as well as raw images, good to verify.
