Open Stack

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,
