To be precise enough, you are referring to "Images" table in Glance database. Is this correct? I also see an image_properties table that has a column "deleted" and ID.

As for the physical files on the server (usually /var/lib/glance/images), you need to check that against the Glance database: select UUID where deleted =1 You will retrieve a list of unused UUIDs, and these files can be removed as well Razique On 14 Nov 2013, at 0:06, Narayanan, Krishnaprasad wrote: By removing unused images, I mean here is the extra images in the image store which were supposed to be deleted but they still exist.

I think there is not any API for that unfortunately.... But there is a field into the database that indicates the image ID. So if you select all active instances and select the unique images ID entries, you can compare them against the Glance images. A BASH script should be sufficient.

Can I know are there any APIs in Glance or Nova that can help me in this process? Thanks, Krishnaprasad
