This problem where files/dirs are deleted is fixed in http://www.open-iscsi.org/bits/open-iscsi-2.0-870-rc3.tar.gz Alternatively, with older tools you could run iscsiadm with the portal argument: "/sbin/iscsiadm -m node -T TARGET -p ip:port,tpgt -o update -n node.session.timeo.replacement_timeout -v 2400" So you need to pass the portal info.

What open-iscsi version? In the current version on open-iscsi.org if a record in /etc/iscsi/nodes is not found, when iscsid starts up it will re-setup the session with a combination of iscsid.conf settings and values that are currently being used. The replacement timeout shuold be one of these that is taken from iscsid.conf. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "open-iscsi" group.
