[Lustre-discuss] Lustre 1.8.1 and ISCSI Kernel support

[Shuichi Ihara]

Hi,

I saw that similar problem was posted on ofed list and I got same error before.
http://lists.openfabrics.org/pipermail/general/2009-June/060027.html

I'm also using the lustre with iscsi for just testing, but I built open-iscsi
from the tarball and installed it. http://www.open-iscsi.org/

Hope this helps.

Thanks
-Ihara
