Hello,<br><br>Thank you for your answer.

<br>I use open-scsi instead of iscsi-initiator but the problem still there.<br>Have you any suggestions? Why don't you have the problem if you have the same config? do you have crc32c as a module?<br><br>Thanx you<br>

Yes, it's now working well on my test environment. I built a rpm for<br>
the patched kernel by myself. Well, you also need to stop default iscsi-initiator<br>
service which is enabled by iscsi-initiator-utils. (/etc/init.d/iscsi stop)<br>
<br>
Try attached my simple rpm spec file and here is a quick procedure.<br>
1. download tarball open-iscsi-2.0-871.tar.gz from <a href="http://www.open-iscsi.org" target="_blank">www.open-iscsi.org</a><br>
2. build open-scsi rpm package with attached spec file<br>
3. uninstall iscsi-initiator-utils package<br>
4. install open-iscsi-2.0-871_xxxx and start initiator by /etc/init.d/open-iscsi start<br>

Hi,<br>
<br>
Thank you for your answer.<br>
I've tried compiling open-isicsi, but it seems to be the same :<br>
Aug 26 10:40:45 lfs1 kernel: connection1:0: Could not create connection due to crc32c loading error. Make sure the crc32c module is built as a module or into the kernel<br>
<br>
I've just compiled open-iscsi like that :<br>
make KSRC=/usr/src/kernels/2.6.18-128.1.14.el5_lustre.1.8.1-x86_64<br>
Evrything seemed to be OK. But it's impossible to mount ISCSI target with this way too...<br>
Have ytou compiled it like that? Evrything works fine for you? Could you tell me the rpm you use?<br>
<br>
Someone have another idea?<br>
<br>
Thank you<br>
<br>
Best regards<br>
<br>
Hindisvik<br>

Hi,<br>
<br>
I saw that similar problem was posted on ofed list and I got same<br>
error before.<br>
<a href="http://lists.openfabrics.org/pipermail/general/2009-June/060027.html" target="_blank">http://lists.openfabrics.org/pipermail/general/2009-June/060027.html</a><br>
<br>
I'm also using the lustre with iscsi for just testing, but I built<br>
open-iscsi<br>
from the tarball and installed it. <a href="http://www.open-iscsi.org/" target="_blank">http://www.open-iscsi.org/</a><br>
<br>
Hope this helps.<br>
<br>
Thanks<br>

Hi,<br>
<br>
Thank you for your answer, it was a great idea to install kernel-ib-1.4.1-2.6.18_128.1.14.el5_lustre.1.8.1.x86_64.rpm<br>
since it<br>
provides me the ISCSI modules needed! Thanx for that.<br>
<br>
So now, I can start iscsid service and launch :<br>
iscsiadm -m discovery --type sendtargets --portal 192.168.0.253<br>
... but I still have a problem when I want to connect my target :<br>
iscsiadm -m node -T iqn.2008-07.fr.xxx:xxx.disk1.sys1.xyz -p<br>
192.168.0.253 -l<br>
<br>
It gives me the following error :<br>
iscsiadm: Could not login to [iface: default, target:<br>
iqn.2008-07.fr.xxx:xxx.disk1.sys1.xyz, portal:<br>
192.168.0.253,3260]:<br>
iscsiadm: initiator reported error (9 - internal error)<br>
<br>
Aug 26 09:19:24 lfs1 kernel: session2: couldn't create a new<br>
connection.<6>scsi7 : iSCSI Initiator over TCP/IP<br>
Aug 26 09:19:24 lfs1 kernel: connection3:0: Could not create<br>
connection due to crc32c loading error. Make sure the crc32c<br>
module<br>
is built as a module or into the kernel<br>
Aug 26 09:19:24 lfs1 iscsid: received iferror -12<br>
Aug 26 09:19:24 lfs1 iscsid: can't create connection (115)<br>
<br>
It seems there's a problem with the crc32c module, which is<br>
needed<br>
to mount an ISCSI target. If I use a non lustre patched<br>
kernel like<br>
: 2.6.18-128.1.14.el5 the module is compiled ionto the kernel and<br>
everything works fine.<br>
<br>
What can I do?<br>
Have someone encountered this problem?<br>
<br>
Thank you by advance.<br>
<br>
Best regards,<br>

Hi Hindisvik,<br>
<br>
iSCSI support is switched off in the lustre kernels, but<br>
it should<br>
be available from the kernel-ib package, see this thread:<br>
<br>
<a href="http://lists.lustre.org/pipermail/lustre-discuss/2009-July/011068.html" target="_blank">http://lists.lustre.org/pipermail/lustre-discuss/2009-July/011068.html</a><br>
<br>
I tried that with 1.8.0, but did not succeed: the iSCSI<br>
modules<br>
could not be loaded, so I compiled my own kernel in the end.<br>
<br>
I did not check with 1.8.1, but if you succeed I would be<br>
very<br>
interested to know.<br>
<br>

Hello,<br>
<br>
I've downloaded the last release of Lustre (1.8.1) in<br>

lustre-modules-1.8.1-2.6.18_128.1.14.el5_lustre.1.8.1.x86_64.rpm<br>
<br>
I'd like to use Lustre with a ISCSI storage device,<br>
and it<br>
seems this kernel does not support ISCSI (?!)<br>
(scsi_transport_iscsi.ko). Have someone encouter this<br>
problem? Is there another version with SCSI support? What<br>
can I do?<br>
<br>
Thank you be advance for any suggestion.<br>
<br>
Best regards<br>
