I did some more testing today. I created a target with discoveryd enabled. First, I verified it was working normally by setting startup to automatic, logging out of the target, and letting the discovery daemon recreate the session for me. All was working normally. Then I logged out of my session from the command line, and deleted the "node" record. When the discovery daemon next ran for that target, it re-logged in, though it did not create the "node" entry in the database. So it looks like it worked correct after a node deletion. -- You received this message because you are subscribed to the Google Groups "open-iscsi" group.
