I see, thanks for the feedback guys! It is interesting that Ceph Manager does not allow us to export iSCSI blocks without selecting 2 or more iSCSI portals. Therefore, we will always use at least two, and as a consequence that feature is not going to be supported. Can I export an RBD image via iSCSI gateway using only one portal via GwCli? @Maged Mokhtar, I am not sure I follow. Do you guys have an iSCSI implementation that we can use to somehow replace the default iSCSI server in the default Ceph iSCSI Gateway? I didn't quite understand what the petasan project is, and if it is an OpenSource solution that we can somehow just pick/select/use one of its modules (e.g. just the iSCSI implementation) that you guys have.
