Not exactly. iscsid.conf is used as the default settings for the node/portal records. When you run the iscsiadm discovery/new command then iscsiadm will create records in /etc/iscsi/nodes or /var/lib/iscsi/nodes (depends on the version) for each portal found/setup. When you run iscsiadm -m node -o show you are seeing those values in the db. When the iscsi service starts (when we login to a target), iscsiadm reads the db and uses those settings for each session. So some of those settings might be what we ask the target to use but we might end up negotiating some other value with the target. >> On the F16 system is iscsid running? > > Apparently (systemctl reports the service as running): > root 795 0.0 0.0 12908 656 ?

Note that if the connection is lost for longer than node.session.timeo.replacement_timeout then you are basically out of luck. IO errors will get to the root fs and it will panic. For F16 you would want to set that to -1 instead of 9999999. -- You received this message because you are subscribed to the Google Groups "open-iscsi" group.
