This is the expected behaviour. The volume lifecycle has nothing to do with the server lifecycle. Volumes contain potentially important data which is totally independent from the servers that process it, and since Nova doesn't know what data you keep on the volume, it doesn't touch it. Imagine - you decommission a physical server, and automatically throw away all the LUNs that were connected to it. I don't think your boss would be happy to lose your company's client database, for example. I believe that volume attachment has a flag to automatically delete the volume when the instance is deleted. But you must set it explicitly. -----Original Message----- From: kjme001@gmail.com <kjme001@gmail.com> Sent: Monday, July 8, 2024 2:28 AM To: openstack-discuss@lists.openstack.org Subject: when deleting an instance, its volume is not deleted I have the following problem, when deleting an instance, its volume is not deleted along with it, the volume remains and I then have to execute the command to detach the volume from the non-existent instance and then delete it. I don't know what could be causing this, the volume should probably be deleted together with the instance being deleted Thank you for your help
