Wierd problem with current GIT version of open-iscsi
Mike, I decided to try the current repository version (as of 3PM, 7/15). Compiled and installed w/o issue. Rebooted and I couldn't connect to my EQL targets. The login process complained no iSCSI driver.So I installed 2.0-871 from the website tar ball. Rebooted, same problem. Tried an older kernel, 2.6.24-23, came up fine. Installed (stupidly) the git version on that kernel, reboot, couldn't log in either. Again, trying to downgrade failed. Installed an even older kernel, 2.6.24-22 installed 871 from the tar ball, that worked fine. Removed the modified kernels and re-installed one, 2.6.24-24, then installed 871 from tar ball, works fine. I'm running ubuntu 8.04 LTS. 2.6.24-24-generic kernel right from ubuntu. Is this anything you've seen? What I see in the log that's different is, non-working configs had these errors. Jul 15 15:17:56 ietd-tape kernel: [ 73.760376] Loading iSCSI transport class v2.0-871.

Re: Wierd problem with current GIT version of open-iscsi
Thanks. It's working on my test VM after running a #depmod -a However, after a reboot you have to do #depmod -a again. Then relogin your targets. ext3 filesystem, noatime, read ahead set to 8K, Jumbo frames set to 9000. It's a few MB slower with standard frames. A quick 'dt' run with one GbE interface. r...@ubuntu-804-svr:/src/dt.d# ./dt of=/mnt/test/test.dt bs=8k pattern=0x3939393 9393939 disable=compare capacity=5G Write Statistics: Total records processed: 655360 @ 8192 bytes/record (8.000 Kbytes) Total bytes transferred: 5368709120 (5242880.000 Kbytes, 5120.000 Mbytes) Average transfer rates: 101181853 bytes/sec, 98810.403 Kbytes/sec Number I/O's per second: 12351.300 Total passes completed: 0/1 Total errors detected: 0/1 Total elapsed time: 00m53.06s Total system time: 00m16.00s Total user time: 00m00.13s Starting time: Wed Jul 15 17:52:35 2009 Ending time: Wed Jul 15 17:53:28 2009 Read Statistics: Total records processed: 655360 @ 8192 bytes/record (8.000 Kbytes) Total bytes transferred: 5368709120 (5242880.000 Kbytes, 5120.000 Mbytes) Average transfer rates: 109386901 bytes/sec, 106823.146 Kbytes/sec Number I/O's per second: 13352.893 Total passes completed: 1/1 Total errors detected: 0/1 Total elapsed time: 00m49.08s Total system time: 00m05.67s Total user time: 00m00.03s Starting time: Wed Jul 15 17:52:35 2009 Ending time: Wed Jul 15 17:54:17 2009 Total Statistics: Output device/file name: /mnt/test/test.dt (device type=regular) Type of I/O's performed: sequential (forward) Data pattern string used: '0x39393939393939' Data pattern read/written: 0x39337830 (data compare disabled) Total records processed: 1310720 @ 8192 bytes/record (8.000 Kbytes) Total bytes transferred: 10737418240 (10485760.000 Kbytes, 10240.000 Mbytes) Average transfer rates: 105124518 bytes/sec, 102660.662 Kbytes/sec Number I/O's per second: 12832.583 Total passes completed: 1/1 Total errors detected: 0/1 Total elapsed time: 01m42.14s Total system time: 00m21.67s Total user time: 00m00.16s Starting time: Wed Jul 15 17:52:35 2009 Ending time: Wed Jul 15 17:54:17 2009 On Wed, Jul 15, 2009 at 4:40 PM, Donald Williams don.e.willi...@gmail.com wrote: I'll try running depmod and see if that helps.

There is a new iscsi module, so there is now iscsi_tcp libiscsi_tcp libiscsi scsi_transport_iscsi The above error log messages indicated that you are using a newer iscsi_tcp module but the libiscsi_tcp is not getting loaded. I think we have been getting lucky and since the older modules were the same as the distro they got loaded right. Now with the new module we should probably add a depmod in the Makefile somewhere.
