Hi, i trhink you have the same problem like me -> #242

can you show us the output from:

# rados lspools

# cat /etc/ceph/iscsi-gateway.cfg

#  gwcli -d  (on booth nodes)

# /var/log/rbd-target-api/rbd-target-api.log (show us te end of the log)

#  cat /etc/ceph/ceph.client.admin.keyring

I am facing a similar issue and I am unable to start the rbd-target-api at all. It exits with an error.

I got same problem, I fixed through:

cp ceph.client.crash.keyring to /etc/ceph/ceph.client.crash.keyring
