Error when deleting Image in glance with rbd backend
Hi,
i'm trying to delete images from glance but this failes with an error, that the backend does not have the capabilities to delete images.
I'm using the same configuration for creating images within rbd backend and this works. Cinder does also has the capabilities to create and delete volumes on the backend.
This is the config I use for the rbd backend.
Ceph auth on ceph mon host:
# ceph auth list
client.glance
key: AQDvyE9eU2+FFhAAaQRc4IAif/DJkqWnx6FmEQ==
caps: [mon] allow r
caps: [osd] allow class-read object_prefix rbd_children, allow rwx pool=images,allow rx pool=volumes
Now the ceph.conf on the glance host:
# cat /etc/ceph/ceph.conf
[client]
rbd cache = true
rbd cache writethrough until flush = true
admin socket = /var/run/ceph/guests/$cluster-$type.$id.$pid.$cctid.asok
log file = /var/log/qemu/qemu-guest-$pid.log
rbd concurrent management ops = 20
[client.cinder]
keyring = /etc/ceph/ceph.client.cinder.keyring
[client.glance]
keyring = /etc/ceph/ceph.client.glance.keyring
[client.nova]
keyring = /etc/ceph/ceph.client.nova.keyring
This is the glance-api.conf

Can you please run delete command with debug option and provide log
openstack image delete 5aafce2a-5a32-4764-9820-11cb2ee8aaef --debug
Hi, I posted the logs in a new answer as the comment section is limited in characters.
Has this worked before or are you dealing with it since the beginning? I would try to create and delete an image with the rbd command to rule out the ceph layer. Try
rbd --id glance -k <KEYRING_PATH> -p images create --image test -s 1Gand then delete it with the same parameters.Also check if the image has snapshots that weren't cleaned up:
rbd -p images snap ls 5aafce2a-5a32-4764-9820-11cb2ee8aaef. If there's more than the one regular glance snapshot I would check if they can be deleted.Hi, there is only one regular snapshot. Creating and deleting images works flawlessly
