Hi, I just looked through the rbd driver of OpenStack cinder. It seems there is no additional clear_volume step implemented for rbd driver. In my case, objects of this rbd image were deleted partially, so I doubt it’s related Ceph instead of Cinder driver. br, Xu Yun > 2020年1月15日 下午7:36，EDH - Manuel Rios <mriosfer@xxxxxxxxxxxxxxxx> 写道： > > Hi > > For huge volumes in Openstack and Ceph, setup in your cinder this param: > > volume_clear_size = 50 > > That will wipe only the first 50MB of the file and then ask to ceph to fully delete instead wipe all disk with zeros that sometimes in huge volumes cause timeout. > > In our deploy that was the solution, Openstack Queens here > > > -----Mensaje original----- > De: Eugen Block <eblock@xxxxxx> > Enviado el: miércoles, 15 de enero de 2020 8:51 > Para: ceph-users@xxxxxxx > Asunto: Re: Objects not removed (completely) when removing a rbd image > > Hi, > > this might happen if you try to delete images/instances/volumes in openstack that are somehow linked, e.g. if there are snapshots etc. I have experienced this in Ocata, too. Deleting a base image worked but there were existing clones so basically just the openstack database was updated, but the base image still existed within ceph. > > Try to figure out if that is also the case. If it's something else, check the logs in your openstack environment, maybe they reveal something.
