I don't know anything about systemd timers, but there should be no reason for this. What distro are you using? What iscsi service files are there, and which ones are enabled? In SUSE we have iscsid.socket, iscsid.service, and iscsi.service. The first two are for the iscsid daemon, and the last is for iscsi logins/logouts. Then, if you're using broadcom, you might also have iscsiuio.socket and iscsiuio.service. I investigated a bug once where a customer was unhappy the iscsi service was taking so long to startup, according the systemd "blame", but it really wasn't taking a long time, but the dependencies made it look that way. You can always completely disable iscsi serivces and compare the actual boot time to when it is enabled to see if it really impacting your boot time. -- You received this message because you are subscribed to the Google Groups "open-iscsi" group.
