Hi,
rbd list --pool erasure42 return a empty list.
that's because the rbd metadata is stored in a replicated pool. You
need to look into your replicated pool to delete the test image. If
you don't find it with:
rbd list --pool <replicated_pool>
you can inspect the rbd_data prefix of the EC chunks and then find the
corresponding rbd image:
# retrieve the rbd_data prefix:
rados -p openstack-ec ls | head -1
rbd_data.2.c142ac217af172.0000000000000120
# myrbdprefix="c142ac217af172"; for i in $(rbd -p images ls); do if [
$(rbd info --format json images/$i | jq -r '.block_name_prefix' | grep
-c "$myrbdprefix") -eq 1 ]; then echo "your image is: " $(rbd info
--format json images/$i | jq -r '.name'); break; fi; done
your image is: volume-6cc34ae0-910f-475e-a097-7f374f4a8d57
To remove the image, you would need to issue that command for the
replicated pool, not the EC pool:
rbd rm <replicated_pool>/<image>
Then check your EC object list again.

Hi,
I got two pool one replica 3 and another with EC 4+2 for rbd.
During my test to access from a KVM hyperviseur I create a image with meta
data in the replica 3 pool and the data in the EC 4+2.
After I end the test (where everything works) I can't see anything in
erasure42 pool.
rbd list --pool erasure42
return a empty list. But

it still use 336GiB.
How can I find where those 336Gib are and delete the image or whatever.
