Hi list, I've already sent this to the open-iscsi mailing list, but I guess this is more relevant for linux-rdma.
Finally I've got IB/iSER running on Debian Squeeze with Linux kernel 3.0 smoothly. The problem was that we did not have the suitable OFED for our kernel and we did not use the open-iscsi from OFED. Kernel 3.0 is supported since OFED-1.5.4 from 2011-12-05. So, I've taken the 1.5.2-based stuff from Debian/Experimental and I've updated it to 1.5.4 from OFA. Then, I've noticed that Debian doesn't build "ib_iser" in the OFA kernel source and that they don't build the open-iscsi kernel/user-space code - I made it do so. The next problem was that open-iscsi kernel code in OFED-1.5.4 is for <= 2.6.32 based RedHat distributions. I had to port the source from 2.6.30 to 3.0 due to kernel API changes. OFA even forgot libiscsi_tcp.[ch] in OFED-1.5.4. So, I had to import it from 2.6.30 mainline. I did so, because we wanted to compare TCP and iSER speed over InfiniBand. Our Solaris COMSTAR targets provide both. After fixing the kernel, there was still a problem in the open-iscsi 2.0.869 user-space from OFED. Some sysfs magic has changed - so that the iSCSI host number couldn't be found. After fixing that, it worked for me.
