GlusterFS Tips and Tricks CentOS

by on February 10, 2013 at 4:39 pm

I’ve been playing around with the latest stable release of GlusterFS, currently 3.3.1, for the last couple of weeks.  GlusterFS is a scale-out cluster storage system that is extremely easy to setup and get running.  However, during my short time working with it, I’ve stumble across a few items that were a little tricky to solve, and not well documented in the FAQ or elsewhere (that I found).

Problem: Attaching a Peer

The first problem I ran into was the inability to successfully attach a peer.  After running gluster peer attach gluster-node2 I would receive “Probe unsuccessful” “Probe returned with unknown errno 107″  Suffice to say that when an application gives you an “unknown error” it is very demoralizing.  Especially if you read Gluster’s documentation about how easy it is to setup.  If you check in /var/log/glusterfs/etc-glusterfs-glusterd.vol.log you can generally find some text that points to the problem.

Fedora 18 Review

by on February 7, 2013 at 6:37 pm

Fedora FreedomFedora 18 was released in the middle of last month without too much fanfare.  I suspect this is likely because the beta was extremely buggy; many people had trouble installing Fedora 18 Beta using the new Anaconda installer interface, and I myself even filed a bug report for GRUB2 not loading after installation (which is still outstanding).

Why should you be interested in Fedora 18?  Well, aside from the fact that it’s already a very popular desktop distro, according to this article from ServerWatch.com, Fedora 17 and Fedora 18 will debut some of the features slated for release in RHEL 7, which is due out within the next year or so.

Fedora 18 Beta Screen Shots and Review

by on December 1, 2012 at 10:14 pm

Fedora 18 beta has finally been released, after much delay.  If you’re a follower of the Red Hat world, then you know Fedora 18 is likely going to serve as part of the upstream base for Red Hat Enterprise Linux 7, which is reportedly supposed to be released in beta form sometime next year.  Also, I feel Fedora is now really offering a great user experience and deserves to be explored as a primary desktop distro.

Debian 7 Wheezy testing

by on September 7, 2012 at 9:58 pm

Well, I had been putting it off for some time, but I finally installed Debian testing, aka “Wheezy.”

There are rumors on the internet about this shipping with Xfce to fit on a single CD, however I downloaded and installed the latest weekly build, and it indeed came with Gnome 3.  In my case, I installed the OS into Virtual Box.  Gnome 3 failed to launch, and I only had the fail safe mode.  On Fedora 17, I get the full Gnome 3 desktop with the same settings in Virtual Box, which leads me to believe Fedora might be using a newer package or better VM video drivers.

I think Gnome 3 is a step in the wrong direction for Linux, and I’ll be majorly happy if Debian indeed switches to Xfce for desktop use.

As far as the installation of the OS goes, it’s pretty straight forward, much the same as Squeeze.  A few minor changes, and a very ugly pink loading bar.  It’s not ugly strictly because it’s pink, just that it doesn’t fit with the other colors of the screen.  I know this is fickle, but just my opinion ;)


Anyway, if you actually read this and found it helpful, I’m glad :)

Fun With Debian Linux

Fun With Debian

What’s fun about Debian Linux?  Everything.  The amount of packages available for Debian Stable, currently Sqeeze, is astounding.  Stability is second to none, in my opinion, and uptime is measured in months and years.  In fact, in most production Debian systems I help manage, the number 1 cause of server downtime is hardware related.  In fact, I’d say that’s the only cause of downtime for quite a few production environments.  If you keep Debian patched and secure, your administration experience will be blissful.
