[Lustre-discuss] Installing Lustre client on 2.6.18-194 kernel
Hi, I have installed lustre client packages on a client node. But it doesn''t mount the lustre file system from lustre server. It gets the following famous error: $ mount -t lustre 192.168.0.1:/lustre /mnt/lustre mount.lustre: mount 172.16.113.232:/lustre at /mnt/lustre failed: No such device Are the lustre modules loaded? Check /etc/modprobe.conf and /proc/filesystems Note ''alias lustre llite'' should be removed from modprobe.conf As I was searching through the mailing list, I have noticed that lustre.ko should be present in this directory: /lib/modules/2.6.18-194.17.4.el5/kernel/fs/lustre/lustre.ko My current kernel is 2.6.18-194.17.4.el5. but lustre.ko is in 2.6.18-164.11.1.el5 instead. So I guessed that this may be the source of problem. Any ideas? Thanks -------------- next part -------------- An HTML attachment was scrubbed...

If one is not available you will have to build it from the source. b. -------------- next part -------------- A non-text attachment was scrubbed...

[Lustre-discuss] Installing Lustre client on 2.6.18-194 kernel
Well, I want to install client module on rocks 5.5 x86_64. there are some packages in source section of lustre download area. I am confused which one to choose? what are the differences between them? lustre-client-source-2.0.0.1-2.6.18_164.11.1.0.1.el5_lustre.2.0.0.1.i686.rpm lustre-client-source-2.0.0.1-2.6.16_60_0.42.8_lustre.2.0.0.1_smp.x86_64.rpm lustre-client-source-2.0.0.1-2.6.27_23_0.1_lustre.2.0.0.1_default.x86_64.rpm lustre-client-source-2.0.0.1-2.6.18_164.11.1.0.1.el5_lustre.2.0.0.1.x86_64.rpm lustre-client-source-2.0.0.1-2.6.16_60_0.42.8_lustre.2.0.0.1_bigsmp.i686.rpm lustre-client-source-2.0.0.1-2.6.27_23_0.1_lustre.2.0.0.1_default.i686.rpm lustre-client-source-2.0.0.1-2.6.18_164.11.1.el5_lustre.2.0.0.1.i686.rpm lustre-client-source-2.0.0.1-2.6.18_164.11.1.el5_lustre.2.0.0.1.x86_64.rpm and one other thing! where is the source for lustre-client-modules?

[Lustre-discuss] Installing Lustre client on 2.6.18-194 kernel
Our kernel is also 2.6.18_194.17.4.el5. We installed OFED 1.5.2 from source, following this guide: https://wiki.rocksclusters.org/wiki/index.php/Install_OFED_1.5.x_on_a_Rocks_5.3_cluster ... which left us, among other things, a folder /usr/src/ofa_kernel. Lustre on the server side is handled by our vendor, so all we needed to worry about is the client. To build a lustre client, we then installed lustre-1.8.5.tar.gz from source, not from rpms. Our first compile produced the error you show below. # ./configure --with-linux=/lib/modules/`uname -r`/build # make rpms To get the lustre installation to use our new OFED, we tried this and it worked. # ./configure --with-o2ib=/usr/src/ofa_kernel --with-linux=/lib/ modules/`uname -r`/build # make rpms RPMs showed up in /usr/src/redhat/RPMS/x86_64, and we are using lustre-1.8.5*.rpm and lustre-modules-*.rpm on our client machines.

[Lustre-discuss] Installing Lustre client on 2.6.18-194 kernel
For lustre client, we did not need to alter our kernel at all. We just made and installed lustre-1.8.5 and lustre-modules-1.8.5 rpms. /etc/ modprobe.conf needs a tweak. For lustre server, I believe you will need to deal with a patched kernel. We have not been down this road yet since our vendor includes lustre server software with their hardware.
