Please excuse the garbled proverb, I don’t mean to say that people in Rome shouldn’t use GitHub. Instead, I’m talking about using the right tool for the job and the community. Sometimes the “right” tool is completely wrong, because the audience is wrong for the tool. Collaboration works well when you use the right tools. For developers, […]

I’m here in New Orleans at Linux Con, hacking on puppet-gluster and talking to lots of interesting folks. I’ve met gluster hacker Theron Conrey, and my host John Mark Walker, Fedora and Raspberry Pi experts Spot and Ruth Suehle, and many … Continue reading →

After quite some delay, I have been able to try out a work-in-progress kernel-tree (3.7) from Sascha Hauer for the Genesi EFIKA MX Smartbook. The Fedora Remix image I have created uses the barebox bootloader to load the device-tree and the kernel (a…

Recently I bought a new keyboard, which I intend to use when my laptop is placed in its docking station. There are two external monitors connected, making the display of the laptop rather useless (only two outputs are supported at the same time). In no…

Automatic network configuration with DHCP is great. But if you need to use multiple separated networks at once, it gets more difficult pretty quickly. For example, my RHEL-6 laptopconnects through wifi to the network at home, which provides i…

Not all projects I am regularly working on use the same CodingStyle. This is very unfortunate, and sometimes makes it time consuming to provide acceptable patches. One common example is that some project indent with a <tab>, where others expect <4-spaces>/>.

I could not find a vim plugin or other extension that lets me pick vim-settings per git repository. The idea that I came up with, is to set the project specific vim-settings in the git-config itself. For example:

$ git config --add vim.settings 'tabstop=4 expandtab'

Now, in my ~/.vimrc, I have the following snippet:

let git_settings = system("git config --get vim.settings")
if strlen(git_settings)
    exe "set" git_settings
endif

Editing a file in the git repository that contains the above vim.settings, now replaces my <tab> by <4-spaces>. Other repositories that do not have the vim.settings will fall-back to my vim defaults. If you can think of any improvements or suggestions, please share them.

The Fedora Project’s infrastructure team needed a way to ensure the reliability of its Fedora Hosted service, while making the most of their available hardware resources. The team tapped GlusterFS replicated volumes to convert what had been a two-node, active/passive, eventually consistent hosting configuration into a well-synchronized setup in which both nodes could take on […]

Back in February 2011, when I joined what ultimately became part of the GlusterFS development team at Red Hat, I had already been interested in low power — as in low power consumption — computing for a long time. For most of my earlier explorations I had used a Linksys WRT54G[1] router — which uses …Read more

This sets up a GlusterFS Unified File and Object (UFO) server on a single node (single brick) Gluster server using the RPMs contained in my YUM repo at http://repos.fedorapeople.org/repos/kkeithle/glusterfs/. This repo contains RPMs for Fedora 16, Fedora 17, and RHEL 6. Alternatively you may use the glusterfs-3.4.0beta1 RPMs from the GlusterFS YUM repo at http://download.gluster.org/pub/gluster/glusterfs/qa-releases/3.4.0beta1/ …Read more

One of the cooler new features in oVirt 3.1 is the platform’s support for creating and managing Gluster volumes. oVirt’s web admin console now includes a graphical tool for configuring these volumes, and vdsm, the service for responsible for controlling oVirt’s virtualization nodes, has a new sibling, vdsm-gluster, for handling the back end work. Gluster and […]

It seems that the maintainer of the wireshark package in Fedora has updated to version 1.8.1 in the current Fedora Rawhide, which will become Fedora 18. The schedule tells us that Fedora 18 is planned to be released on 2012-11-06 (the latest schedule m…

Within the past couple weeks, Fedora and Gluster rolled out new versions, packed with too many features to discuss in a single blog post. However, a couple of the stand-out updates in each release overlap neatly enough to tackle them together–namely, the inclusion of OpenStack Essex in Fedora 17 and support for using Gluster 3.3 as a […]

A lot of changes were committed recently to the gluster-wireshark repository. A lot of effort was put into the details (click on the image to enlarge):UUIDs and GFIDs are now displayed as 4-2-2-2-6 bytesflags for OPEN, CREATE etc are now shown in detai…

[From an email to the gluster-devel mailinglist]  today I have merged support for GlusterFS 3.2 and 3.3 into one Wireshark ‘dissector’. The packages with date 20120516 in the version support both the current stable 3.2.x version, and the latest 3….

My Fedora 17 Beefy Miracle alpha1 ARM system does not any contents in /var/log/messages. This is very impractical for troubleshooting. The command systemd-journalctl –no-tail shows that rsyslog.service fails to start correctly. Bummer!Starting the dae…

Slow but steadily I am improving the packet dissector for Gluster. Once it is in a more complete state, it’ll be submitted for inclusion in Wireshark. Until that time (which will likely take some more months), updated versions of Wireshark for RHEL6 an…
