Hi, I am trying to build lustre 2.5.0 against MLNX_OFED_LINUX-2.2-1.0.1-rhel6.4-x86_64 on CentOS6.4 with kernel version 2.6.32-358. But I am not able to set lnet config settings properly. I used settings suggested in lustre 2.x manual. But then not able to get network up using lctl. Details: I have two server machines, one for mgs+mdt and second for oss and one client machine. I want to setup Infiniband on all these machines. I could run below steps successfully for all the three machines: 1. Run script mlnxofedinstall # ./mlnxofedinstall -vvv --add-kernel-support --without-32bit --without-fw-update --hpc 2. Restart openibd service # /etc/init.d/openibd restart 3. configure ib0 interface. 4. configure lustre with o2ib # ./configure --with-linux=Path_to_linux-2.6.32-358.18.1.el6 --with-o2ib=/usr/src/ofa_kernel/default/ 5. make lustre rpms: # make rpms This gave me below compilation error I looked online for this error and found bug registered on the same: https://jira.hpdd.intel.com/browse/LU-4266 Below patch from above link solved the problem and hence I could build lustre rpms: http://review.whamcloud.com/#/c/8451/1 Now first I want to do the Infiniband setup for mgs and mdt on single machine which also has Ethernet IP. Then I want to format and mount mgs and mdt. So I installed above created lustre rpms and then added below line in /etc/modprobe.d/lustre.conf options lnet networks=o2ib(ib0) Then I rebooted the machine to remove all lustre related modules including lnet and then ranmodprobe lnet command to add above parameters and the ran lctl network up which is giving me below error: LNET configure error 100: Network is down I looked online and found below discussion on same error: http://lists.lustre.org/pipermail/lustre-discuss/2010-June/013510.html As per suggestion in above mail I tried with below line in /etc/modprobe.d/lustre.conf. In below command for IB_IP, I have given infiniband IP. options lnet *networks=o2ib(ib0)* routes="tcp0 IB_IP@o2ib" This command hangs for around 2 to 3 minutes and then gives error: Write failed: Broken pipe. Same is the case for "options lnet *networks=o2ib(ib0)*" But if I set: options lnet *networks=tcp0(eth0),o2ib(ib0)* routes="tcp1 IB_IP@o2ib" then it gives LNET configure error 100: Network is down. It seems that for network=o2ib(ibo) I am getting error Write failed: Broken pipe. Am I missing anything while following above steps? Or how do I resolve above error? Thanks, Aayush. _______________________________________________ Lustre-discuss mailing list Lustre-discuss-aLEFhgZF4x6X6Mz3xDxJMA@public.gmane.org http://lists.lustre.org/mailman/listinfo/lustre-discuss
