Description

Currently, the dashboard does not check if a given IQN is actually in use when it's deleted.

However, it is possible to get an idea of connected initiators via configFS on the iSCSI gateway nodes.

The number of sessions for a given target IQN can be determined via the contents of:

/sys/kernel/config/target/iscsi/$TARGET_IQN/fabric_statistics/iscsi_instance/sessions

If the ceph-iscsi configuration generates initiator ACLs (e.g. CHAP auth is enabled), then you can see whether an initiator is logged in via:

/sys/kernel/config/target/iscsi/$TARGET_IQN/$TPGT/acls/$INITIATOR_IQN/info

If initiator ACLs are not used, then initiator IQNs for active sessions can be dumped via:

/sys/kernel/config/target/iscsi/$TARGET_IQN/$TPGT/dynamic_sessions
