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- I'm new to Gluster, but am trying to get it set up on a new compute cluster we're building. We picked Gluster for one of our cluster file systems (we're also using Lustre for fast scratch space), but the Gluster performance has been so bad that I think maybe we have a configuration problem -- perhaps we're missing a tuning parameter that would help, but I can't find

Hello, I have installed the Xen 4.1.1 and a working kernel 2.6.32.43 which supports Xen on a Ubuntu Linux 10.04 LTS. However, I have never successfully booted the Hypervisor and Dom0. The screen is always black after some kernel messages rapidly go by. I think that I may pass the wrong parameters to the kernel or Hypervisor with GRUB2. Can any one share his/her working grub.cfg for GRUB2 with

Dear all, I faced a problem with a glusterfs volume (pure distributed, _not_ dispersed) over RDMA transport. One user had a directory with a large number of files (50,000 files) and just doing an "ls" in this directory yields a "Transport endpoint not connected" error. The effect is, that "ls" only shows some files, but not all. The respective log file shows this

Hi all, Does anyone have, or know of a comparison chart of the different network adapters, i.e. 1GB / 10GB, Infiniband, etc. And if possible with a few top brand NIC's and switches listed as well. I would like to see, for example, what the max throughput is of a 1GB NIC (and this could probably differ from PCI to PCIE-x1 to PCIE-x4), and 10GBE. Different switches would probably also have

Hi, is there a way to install aditional drivers or packages to xcp system ? I''m in need to include infiniband card drivers and the ofed stack into it. Thanks in advance! _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

When attempting to boot a system using Infiniband interfaces, ipconfig does not recognize Infiniband NICs as having valid MAC addresses, so they are silently ignored. As I would like to be able to netboot using Infiniband, I have patched ipconfig to support Infiniband interfaces. Fortunately, it's a pretty simple and straightforward patch. Below is the patch for your consideration. ---

We have a new install of CentOS 6.7 with infiniband support installed. We can see the card in hardware and we can see the mlx4 drivers loaded in the kernel but cannot see the card as an ethernet interface, using ifconfig -a. Can you recommend an install procedure to see this as an ethernet interface? Thanks On 05/25/2016 07:32 AM, Fabian Arrotin wrote: > On 25/05/16 03:08, Pat Haley

Hello folks, I am running Xen 2.6 under Centos 5.2 installation, and am trying to port Xen migration abilities to Infiniband. But, the InfiniBand drivers do not work under Xen kernel, only under non-Xen kernels. It looks like I need to install some patches to rectify the situation. Has anyone ever worked with Infiniband and Xen and would be able to give me inputs about the same? I would really

Hi All, We looking for suggestions on dealing with mellanox drivers in CentOS 6.7 We tried installing mellanox drivers (MLNX_OFED_LINUX-3.2-2.0.0.0-rhel6.7-x86_64) on a Quanta Cirrascale server running Centos 6.7 - 2.6.32-573.22.1.el6.x86_64. When we rebooted the machine after installing the drivers, it went into a kernel panic for every installed kernel except for Centos 6.7

Hey guys, I am running gluster over infiniband, and I have a couple of questions. We have four servers, each with 1 disk that I am trying to access over infiniband using gluster. The servers look like they start okay, here are the last 10 or so lines of a client log (they are all identical): 2008-10-07 07:18:40 D [spec.y:196:section_sub] parser: child:stripe0->remote1 2008-10-07 07:18:40 D

I am running XCP 0.5. I have an InfiniBand network in place that I would like to use to connect to my NFS server for VM image storage. Has anybody tried getting IB to work with XCP? Is there a document that outlines the steps for getting IB to work with XCP? Also, I don''t need to expose the IB network to any of the domU. I only want to use the IB network to connecting to NFS based

Hello, I''m trying to get working infiniband device in Xen. I have Xen v3 with 2.6.18 kernel. I export PCI device from Dom0 into DomU. I''ve enabled permisive device in Dom0. However, inserting infiniband module results in the following messages (with little more verbosity which I have added): pcifront pci-0: Installing PCI frontend pcifront pci-0: Creating PCI Frontend Bus

Hi guys, I am testing out some FC storage in my XCP environment but I''m a bit confused on the right way to proceed. XCP actually sees the cards "under hardware in xsconsole". I made a lv available to the XCP box I''m testing on but both fdisk -l and via the XCP cli and ui the lv isn''t there. As I understand it from the documents I''ve read, you

Hello guys, I was wondering if someone could share their glusterfs volume and system settings if you are running glusterfs with infiniband networking. In particular I am interested in using the glusterfs + infiniband + kvm for virtualisation. However, any other implementation would also be useful for me. I've tried various versions of glusterfs (versions 3.2, 3.3 and 3.4beta) over the past

Hello Everyone, I am new with XCP. I''ve setup several hosts with* XCP 1.0* and manage it through XenCenter and command console.

I am trying to setup VMs and VLANs on xenbr3. I created a virtual bridge by
