thanks for this final note/recommendation! .. i will do so .. have deployed the golden image though and so far my engineering users have not complained seems like they are happy with their iscsi root on CentoS! - a. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups open-iscsi group.

Re: in /var/log/messages: conn errors and recovery
Hi Mike, using the Wasabi target and the latest open-iscsi git version (as of today) I still get the errors, which are according to the Wasabi log a time out problem. It only happens when logging in, which used to take about one second or less, but now 5-10 seconds. The messages log on the initiator shows this: scsi6 : iSCSI Initiator over TCP/IP connection1:0: detected conn error (1011) connection1:0: detected conn error (1011) connection1:0: detected conn error (1011) connection1:0: detected conn error (1011) scsi scan: 66 byte inquiry failed.

Re: in /var/log/messages: conn errors and recovery
I need more to the log. The parts above this would tell me what happened. OK, I will capture complete console log next time, sorry, but I rebooted the couple of test boxes that had this node.session.timeo.replacement_timeout = 172800 node.conn[0].timeo.noop_out_timeout = 0 node.conn[0].timeo.noop_out_interval = 0 OK! will do and observe - I just updated the /etc/iscsi/iscsi.conf file and rebooted (working on my golden-build server) ... I also downloaded the latest stable release from the open-iscsi.org site, so that it is now on the 869.2 version as opposed to 865 ... will observe and see if any strange behaviours occur. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups open-iscsi group.

in /var/log/messages: conn errors and recovery
Hello all, After seeing the announcement on the regression of the current release, I looked more closely into my /var/log/messages and noticed that once in a while my iscsi connections get the following: May 8 08:55:48 r05s23 kernel: connection1:0: iscsi: detected conn error (1011) May 8 08:55:49 r05s23 iscsid: Kernel reported iSCSI connection 1:0 error (1011) state (3) May 8 08:55:51 r05s23 iscsid: connection1:0 is operational after recovery (2 attempts) Seems like it recovers, but are these critical issues? My iscsi device is being mounted as my root; should I increase some paramater in /etc/iscsi/iscsi.conf? Any recommendation would be greatly appreciated.
