similar to: mellanox ofed on centos kernel 3.x

Hello, I am having trouble installing the server modules for lustre 2.1.4 and use mellanox''s OFED distribution so we may use infiniband. Would you folks look at my procedure and results below and let me know what you think? Thanks very much! The mellanox ofed installation builds and installs some kernel modules too, so I used this method to ensure OFED compiled against the correct

Greetings Xen user community, I am interested in using Mellanox ConnectX cards with SR-IOV capabilities to passthrough pci-e Virtual Functions (VFs) to Xen guests. The hope is to allow for the use of InfiniBand directly within virtual machines and thereby enable a plethora of high performance computing applications that already leverage InfiniBand interconnects. However, I have run into some

We seemed to have it a stumbling block when building with the above (supported) versions. Our process... 1. Start with stock rhel5 2.6.18-8.1.14 source tree 2. Configure InfiniBand support out of the the kernel (we will build OFED separately). 3. Apply the 1.6.4.2 kernel patches to the kernel source. 4. Build the kernel. 5. Build OFED 1.2 against the patched kernel 6. Build Lustre using

In IRC today, someone who was hitting that same IB performance ceiling that occasionally gets reported had this to say [11:50] <nissim> first, I ran fedora which is not supported by Mellanox OFED distro [11:50] <nissim> so I moved to CentOS 6.3 [11:51] <nissim> next I removed all distibution related infiniband rpms and build the latest OFED package [11:52] <nissim>

Hi All I don't know whether i am asking on a correct list or not i have a query that how to know that what system call are called when packet enters the system or when we send a packet from a system? Thanks

I am trying to compile lustre-1.6.6 against ofed-1.4 using following configure options : ./configure --disable-server --with-o2ib=/usr/src/ofa_kernel-1.4 --with-linux=/usr/src/kernels/2.6.18-92.el5-x86_64 I am getting following errors: configure: error: can''t compile with OpenIB gen2 headers under /usr/src/ofa_kernel-1.4 Is it that lustre-1.6.6 will only work with ofed-1.3. or I am

Hi, I am having problem to bring up the network using lustre 1.6.4.1 (2.6.18-8) with OFED-1.3 (InfiniBand). When I run lctl network up, I''m getting the following: LNET configure error 100: Network is down dmesg shows: LustreError: 21080:0:(api-ni.c:1025:lnet_startup_lndnis()) Can''t load LND o2ib, module ko2iblnd, rc=256 Note that the InfiniBand IPoIB network is working properly

It seems that lustre puts its modules in /lib/modules/2.6.16.21-0.8-default despite the fact that my kernel is 2.6.16.21-0.8-smp ! uname -a Linux n32 2.6.16.21-0.8-smp #4 SMP Sun Sep 24 08:47:30 BST 2006 i686 i686 i386 GNU/Linux make[3]: Nothing to be done for `install-exec-am''. /bin/sh ../../mkinstalldirs /lib/modules/2.6.16.21-0.8-default/kernel/fs/lustre /usr/bin/install -c -m 644

Dear List, We have lots of issues running Glusterfs over Infiniband. The client can mount the share, but when trying to access it by ls, df, touch du or any other kind the client hosts freeze the accessing shell and reboot is hardly possible.

Hi All, I was searching around but was not able to find out. We all know that packet traverses through the Net Filter hooks but how to practically realize that. Please guide Regards Clove

This issue was brought up about a year and a half ago. So I''ll bring it up again and see if anything happens. I''ve got an infiniband network and am attempting to pass the infiniband card through the host and give it to the guest. I''m working with standard CentOS 5.2 on both guest and host with their provided xen (3.0.3 ish). I''ve also attempted to install the

Hello, I see a reproducable panic when doing ibping and aborting it with ^C. My setup is two machines with Mellanox Infinihost III HCAs (one Linux one FreeBSD) connected back-to-back. Details below. I can upload 2 crash dumps, if this is useful. For some reason the port doesn't become ACTIVE, so no packets arrive, but that is probably unrelated. % uname -a FreeBSD cosel.inf.tu-dresden.de
