Hello folks,
  I am trying to share my ceph rbd images through iscsi protocol.

I am trying iscsi-gateway
http://docs.ceph.com/docs/master/rbd/iscsi-overview/


now

systemctl start rbd-target-api
is working and I could run gwcli
(at a CentOS 7.4 osd node)

gwcli
/> ls
o- /
.........................................................................................................................
[...]
  o- clusters
........................................................................................................
[Clusters: 1]
  | o- ceph
............................................................................................................
[HEALTH_OK]
  |   o- pools
..........................................................................................................
[Pools: 1]
  |   | o- rbd
...........................................................................
[(x3), Commit: 0b/25.9T (0%), Used: 395M]
  |   o- topology
................................................................................................
[OSDs: 9,MONs: 3]
  o- disks
..........................................................................................................
[0b, Disks: 0]
  o- iscsi-target
.....................................................................................................
[Targets: 0]


but when I created iscsi-target, I got

Local LIO instance already has LIO configured with a target - unable to
continue


/> /iscsi-target create
iqn.2003-01.org.linux-iscsi.ceph-node1.x8664:sn.571e1ab51af2
Local LIO instance already has LIO configured with a target - unable to
continue
/>

and no more progress at all,

is there something I need to check? something missing? or please direct me
for further debugging.

Thanks in advance

Cheers
Joshua
