Hi, yes, I have read https://docs.ceph.com/docs/octopus/cephadm/stability/ and know that the iSCSI support is still under development.
But why is the command "ceph orch apply iscsi" available
when cephadmin is the orchestrator backend?
I am at the stage that I successfully rolled out an iSCSI gateway
which is visible in the Ceph dashboard.
But when trying to setup a target an error occurs:
Sep 04 15:15:58 ceph02 rbd-target-api[124040]: Unable to create the Target
definition - Could not load module: iscsi_target_mod

Solution:
"modprobe iscsi_target_mod" on the host itself,
the container is not allowed to do that.
