I copied the whole hard disk using dd from the old drive to the new drive. I still had to change the partition layout to use the new space. So I downloaded the gparted ... http://lisas.de/~adrian/?p=722 If I remember it correctly my server at home (file-server, print-server, router, ...) has been installed a long time ago using Red Hat Linux 8.0. Since the initial installation I have done live upgrades using rpm, apt-get or yum to its current version (Fedora 11). Now I just started doing ... http://lisas.de/~adrian/?p=717 The hardware of our cluster is finally installed and ready. All 180 compute nodes (almost) are ready, Infiniband is working and the lustre is mounted. First Infiniband benchmarks gave us results of about 23 GBit/s which is the expected bandwidth with our QDR network. As a mirror admin I am bit frustrated ... http://lisas.de/~adrian/?p=707 Starting tomorrow (2010-03-15), I will be at the 28th Open Grid Forum (OGF28) in Munich for four days. http://lisas.de/~adrian/?p=705 80 compute nodes from our cluster are up and running.

I should have used LVM for / for easy resizing, but I forgot and so I ... http://lisas.de/~adrian/?p=689 Yesterday (2010-02-06) Benjamin and myself were again in Lech/Zürs snowboarding; just like three weeks ago. Last time (2010-01-17) Pattrick and Torsten were also able to join. This time it was only Benjamin and me. The weather was similar to our last visit. Mostly cloudy with a few peeks of sunshine. This ... http://lisas.de/~adrian/?p=681 Since Monday I am at the High Performance Computing Center Stuttgart (HLRS) and I have started the initial installation of our cluster.The people from the HLRS have offered to support us with the initial installation, which we gladly accepted because they know how to do clusters. On Monday I installed the ... http://lisas.de/~adrian/?p=676 Last week I have finally updated our mirror server to Fedora 12. It was still running Fedora 10 which has reached its end of life. The server was running Fedora 10 for a long time and it was always running with a CentOS kernel. The Fedora kernels were, at the ... http://lisas.de/~adrian/?p=671 I am running one of the RPM Fusion builders in a VM using CentOS and after I saw that the newly created VMs on my notebook are using virtio for network and disk access I thought that I will try this also for my builder VM. It was pretty easy ... http://lisas.de/~adrian/?p=655
