Thanks but that is why I am puzzled - the image is there
Can you enable debug logging for the iscsi-gateway-api (add "debug=true" in the config file), restart the daemons, and retry?

Hi, I would appreciate any help/hints to solve this issue iscis (gwcli) cannot see the images anymore
This configuration worked fine for many months What changed was that ceph is "nearly full"
I am in the process of cleaning it up ( by deleting objects from one of the pools) and I do see reads and writes on the cluster as well as images info so not sure what gwcli does not like
( targetcli ls not working either - just froze )
Below some info
ceph version ceph version 13.2.2 (02899bfda814146b021136e9d8e80eba494e1126) mimic (stable)

You will need to re-create that RBD image "vmware01" using the rbd CLI before the iSCSI GW will function.
