Description Rajat Dhasmana 2022-02-01 15:16:30 UTC
When trying to create a glance image we see the following error.
The configuration is glance is using cinder as a backend.

2022-02-01 12:22:04.020 25 ERROR glance.common.wsgi TypeError: temporary_chown() got an unexpected keyword argument 'backend'

Looking good, 


I happened to have the same version deployed on a second environment this time Glance over Cinder over Netapp NFS.
Lets retest again: 

(overcloud) [stack@undercloud-0 ~]$ glance image-create --name rhel7.9 --disk-format qcow2 --container-format bare --file rhel-server-7.9-update-9-x86_64-kvm.qcow2

While Glance is backed by Cinder, which itself is backed by either Netapp iSCSI or NFS.
