Greetings. I''ve reviewed the list archives, particularly the posts from Zakk, on this subject, and found results similar to his. drbd provides a block-drbd script, but with full virtualization, at least on RHEL 5, this does not work; by the time the block script is run, the qemu-dm has already been started. Instead I''ve been simply musing the possibility of keeping the drbd

To start I wish to that you for the swift response on this issue. I do not think that I would get such a quick response from a proprietary (closed-source) company. Open Source :-). To respond to one the comments about large file systems ?recommend you split it in several smaller (2-4TB) filesystems ? This is not feasible in many situations. In some situations 2-4TB is not even a reasonable

Hi all, I have upgraded a test machine from OpenSuSE 11.1 to 11.2. I have found following bug: the server is a 2x quadcore intel box also 2x4=8cpu If you limit the dom0 cpu with dom0-cpus= [1-7]: - [xenwatch_cb] is running 100% cpu and makes var log entry every 65 sec BUG: soft lockup - CPU#X stuck for 61s! - xm commands not work - xend is dead if set dom0-cpus to 0 or 8: - everything looks

Hi, I have two KVM hosts (CentOS 7) and would like them to operate as High Availability servers, automatically migrating guests when one of the hosts goes down. My question is: Is this even possible? All the documentation for HA that I've found appears to not do this. Am I missing something? My configuration so fare includes: * SAN Storage Volumes for raw device mappings for guest vms

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

Hi All, We have a somewhat serious issue around NLB on Windows 2012 and Xen. First, let me describe our environment and then I''ll let you know what''s wrong. 2 X Debian-squeeze boxes running the latest provided AMD64 Xen kernel and about 100GB of RAM. These boxes are connected via infiniband and DRBD is running over this(IPoIB). Each VPS runs on a mirrored DRBD devices. Each

Hi, I am working on the diskless booting over Infiniband networks. At the moment we have created and implemented architecture which allow diskless booting of Linux nodes on x86, x86_64 and Itanium platforms. The system works by booting first small custom made Linux kernel of the Infiniband adapter ROM. The kernel has enough of infiniband stack to setup TCP/IP networking over infiniband. Then it

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. ---

I have an Asterisk server that was running fine until Sunday. Monday there was a power outage and the server was off most of the day. This server has a TE110P, two TDM04B and an Astribank 32. Today I noticed that the TE110P started having IRQ missess. Before today it only had about two or three per month. Today, this is the miss count after ten minutes on: IRQ Misses: 1443

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

Hi, I want to upgrade from 8.0 to 8.1 but yum update does not work. Still 8.0 Probably the cause is that I compiled DRBD myself because it was not available for 8.0 when I set up the machine. Now yum update says: Error: ?Problem 1: cannot install the best update candidate for package drbd-pacemaker-9.11.0-1.el8.x86_64 ? - nothing provides pacemaker needed by

Hi, I've upgrade the kernel to the latest version (C5) and after the update the drbd is not being loaded at reboot time. My previous running kernel was 2.6.18-164.el5. I've checked the /lib/modules/ and /lib/modules/2.6.18-164.10.1.el5/weak-updates/drbd82/drbd.ko -> /lib/modules/2.6.18-164.el5/extra/drbd82/drbd.ko And /lib/modules/2.6.18-164.el5/extra/drbd82/drbd.ko exists 2004
