Hello everyone I have a strange problem and I haven't found the solution yet. Following a certificate update I had to do a "kolla-ansible -t multinode reconfigure ». Well, after several attempts (it is not easy to use certificates with Kolla-ansible, and from my advice, not documented enough for beginners), I have my new functional certificates. Perfect ... well almost. I am trying to create a new instance to check general operation. ERROR. Okay, I look in the logs and I see that Cinder is having problems creating volumes with an error that I never had ("TypeError: 'NoneType' object is not iterable). I dig and then I wonder if it is not the Glance images which cannot be used, while they are present (openstack image list is OK). I create an empty volume: it works. I am creating a volume from an image: Failed. However, I have my list of ten images in glance. I create a new image and create a volume with this new image: it works. I create an instance with this new image: OK. What is the problem ? The images present before the "reconfigure" are listed, visible in horizon for example, but unusable. Is there a way to fix this, or do we have to reinstall them all? Thanks in advance for your help if this problem speaks to you. Franck VEDEL Dép.
