I'm seeing an odd behaviour from sendtargets discovery in open-iscsi on one of our systems. We're running open-iscsi 2.0-871 against a remote linux tgt 0.9.7. discovery.sendtargets.iscsi.MaxRecvDataSegmentLength is set to 262144 to avoid the target list being prematurely truncated.
When I run iscsiadm -m discovery -t sendtargets against the remote target, sometimes it is returning warning messages and aborting halfway through the target list: # iscsiadm -m discovery -t sendtargets -p 0a2bc790-aab9-45bd-ad58-6fd7d9b2aae7.storage.elastichosts.com | wc -l iscsiadm: Cannot resolve host 172.16.226.12. getaddrinfo error: [Servname not supported for ai_socktype] iscsiadm: cannot resolve 172.16.226.12 iscsiadm: failed to add default portal, ignoring target iqn.2008-03.com.elastichosts:ad0b32d2-c220-4be5-a609-5ea063f0a4cc:daaa6df9-0d5d-4d31-b5d7-e3799c9efd4f iscsiadm: failed to add target record iscsiadm: This command will remove the record [iface: default, target: iqn.2008-03.com.elastichosts:ad0b32d2-c220-4be5-a609-5ea063f0a4cc:32367157-899b-4e75-ad4f-2c23d828a92a, portal: 172.16.226.12,3260], but a session is using it. Logout session then rerun command to remove record. iscsiadm: This command will remove the record [iface: default, target: iqn.2008-03.com.elastichosts:ad0b32d2-c220-4be5-a609-5ea063f0a4cc:d79f2d28-8bd0-43d3-b44f-41e863afddda, portal: 172.16.226.12,3260], but a session is using it. Logout session then rerun command to remove record. 55 whereas sometimes it works fine: # iscsiadm -m discovery -t sendtargets -p 0a2bc790-aab9-45bd-ad58-6fd7d9b2aae7.storage.elastichosts.com | wc -l 113 Which of these it does appears to vary from second to second: I can get a couple of failures then a few successes then some failures again, which is very strange! It is entirely possible that this is actually a bug in the tgt target rather than in open-iscsi, of course. Is there an easy way to pinpoint what's going on here? The getaddrinfo error is particularly puzzling.
