Hi cristina, How big is the instance? Is there enough disk space? And is glance running with a filestore backend?

Best regards,

Aihe: Ubuntu Focal Ussuri can't create a snapshot from running instance

Hi all,

I don't have a lot experience with Openstack. I've installed Ussuri on my cloud. I have 1 controller node and 2 compute nodes.

I'm not able to create a snapshot from a running instance, but it works perfectly if the instance is turned off. I checked the logs on controller node about glance-api and POST method executes fine, but suddenly appears a DELETE that seems remove the image:

"POST /v2/images HTTP/1.1" 201 1254 0.045379

"GET /v2/images/c647160b-416d-4c98-bbe2-6302a509f 941 HTTP/1.1" 200 1097 0.014154

I have these versions installed:

- python3-glance-store/focal,now 2.0.0-0ubuntu1 all [instalado, automático]
- python3-glance/focal-updates,now 2:20.0.1-0ubuntu1 all [instalado, automático]

Could anyone help me?

Thanks in advance,

Regards,
