Are you using the tools and kernel modules from 2.0-865? Or the iscsi kernel modules from 2.6.25.6-27.fc8 and tools from the rpm? If you did a make and make install with open-iscsi 2.0-865 from open-iscsi.org then you are using the tools and kernel modules from the open-iscsi.org. > Target is Wasabi Storage Builder. > > Any ideas? Is there anything on the target logs? With a 100 mbs link we might have been sending too much IO, but I would have expected to see some messages about scsi commands timing out and host resets firing. You can try setting these in iscsid.conf: node.session.cmds_max = 16 node.session.queue_depth = 8 Again, set them then rerun discovery and relogin. But if that does not work, and I think if it does it might just be a bandaid, then you should remove the iscsi-initiator-utils rpm by doing rpm -q iscsi-initiator-utils Then run these tools and kernel modules frmom http://www.open-iscsi.org/bits/open-iscsi-2.0-869.2.tar.gz and build it with make DEBUG_SCSI=1 DEBUG_TCP=1 make DEBUG_SCSI=1 DEBUG_TCP=1 install then rerun your test. You might have to reboot or manually unload the old iscsi modules too. > > Thanks, > Ken > > Jun 25 14:16:24 testserver kernel: connection3:0: detected conn error > (1011) > Jun 25 14:16:24 testserver kernel: sd 4:0:0:0: [sde] Result: > hostbyte=DID_BUS_BUSY driverbyte=DRIVER_OK,SUGGEST_OK > Jun 25 14:16:24 testserver kernel: end_request: I/O error, dev sde, > sector 1838511 > Jun 25 14:16:24 testserver kernel: printk: 474 messages suppressed. > Jun 25 14:16:24 testserver kernel: Buffer I/O error on device sde1, > logical block 919224 > Jun 25 14:16:24 testserver kernel: lost page write due to I/O error on sde1 > Jun 25 14:16:24 testserver kernel: Buffer I/O error on device sde1, > logical block 919225 > Jun 25 14:16:24 testserver kernel: lost page write due to I/O error on sde1 > Jun 25 14:16:24 testserver kernel: Buffer I/O error on device sde1, > logical block 919226 > Jun 25 14:16:24 testserver kernel: lost page write due to I/O error on sde1 > Jun 25 14:16:24 testserver kernel: sd 4:0:0:0: [sde] Result: > hostbyte=DID_BUS_BUSY driverbyte=DRIVER_OK,SUGGEST_OK > Jun 25 14:16:24 testserver kernel: end_request: I/O error, dev sde, > sector 1314223 > Jun 25 14:16:25 testserver iscsid: Kernel reported iSCSI connection 3:0 > error (1011) state (3) > Jun 25 14:16:28 testserver iscsid: connection3:0 is operational after > recovery (2 attempts) > > > > > > > --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "open-iscsi" group.
