[openstack-dev] Periodically checking Glance image files

Hi all,

Is there (or was there ever) any plans to implement in Glance a service
that would periodically check that the image files are still available on
the file system (or in whatever storage system being used) and have the
correct checksum?

We had a few issues where an image file was removed from the filesystem and
that can go undetected for a long time until someone tries to access that
image, so we were wondering if it would be possible (and if it would make
sense) to implement some sort of background service to periodically check
if all images found in the database can be retrieved successfully.

Thoughts?

Sergio
