Title:
glance rbd store fill zero to the hole of a rbd
Status in Glance:
New
Bug description:
Right now, glance_store use python binding to do some thing with rbd.
When upload rbd image. Because most of all rbd images are sparse. The
glance_store does not distinguish hole and will fill zero into hole to
rbd.
So, if you use openstack cli to upload a raw image to glance rbd
store, you will find it is too slow.Because it will fill zero to all
the sparse space of raw image to rbd.
I think, we should add check logic into glance_store.
Because glance send the image
to store, glance needs to keep the sparse of the image.
The user can specify the check size of sparse.
