Hello!
I'm working with Openstack Wallaby (1 controller, 2 compute nodes)
connected to Ceph Pacific cluster in a devel environment.
With Openstack Victoria and Ceph Pacific (before last friday update)
everything was running like a charm.
Then, I upgraded Openstack to Wallaby and Ceph to version 16.2.1.
(Because of auth_allow_insecure_global_id_reclaim I had to upgrade many
clients... but that's another story...)
After upgrade, when I try to create a volume from image,
openstack volume create --image
f1df058d-be99-4401-82d9-4af9410744bc debian10_volume1 --size 5
with "show_image_direct_url = True", I get "No valid backend" in
/var/log/cinder/cinder-scheduler.log
2021-04-26 20:35:24.957 41348 ERROR cinder.scheduler.flows.create_volume

[errno 22] RBD invalid argument (error creating clone)
in /var/log/cinder/cinder-volume.log
If I disable "show_image_direct_url = False", volume creation from image
works fine.
I have spent the last four days googling and reading lots of docs, old
and new ones, unlucly...
Does anybody have a clue, (please)?
Thanks in advance!
Javier.-
