Rock the Vote needed a way to manage the fast growth of the data handled by its Web-based voter registration application. The organization turned to GlusterFS replicated volumes to allow for filesystem size upgrades on its virtualized hosting infrastructure without incurring downtime. Over its twenty-one year history, Rock the Vote has registered more than five […]

The sprint is meant for anyone who wants to create apps leveraging the Swift API – which means anyone who’s ever wanted or needed …Read more

This started as a response to a twitter conversation with @DuncanYB and @joshobrien77  re: converged infrastructure. Duncan recently posted a great blog post about Converged compute and storage. Go read that first. I’ll wait here. Welcome back! Ok, to start I agree with Duncan’s comments that Nutanix is certainly in the leader group for what’s… Read more »

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 […]

All good sysadmins know about using tail -f to follow a log file. I use this all the time to follow /var/log/messages and my gluster logs in particular. Maybe everyone already knows this, but it deserves a PSA: after a … Continue reading →

GlusterFS is a distributed file system implemented in user space. It is strictly not a native file system in itself but is an aggregator of different file systems. GlusterFS can aggregate individual file system mount points or directories (called bricks in gluster terminology) to provide a single unified file system namespace. In addition to NFS […]

A little while back, I tested out the Unified File and Object feature in Gluster 3.3, which taps OpenStack’s Swift component to handle the object half of the file and object combo. It took me kind of a long time to get it all running, so I was pleased to find this blog post promising a […]

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 […]

I’ve been working on a puppet module for gluster. Both this, my puppet-gfs2 module, and other puppet clustering modules all share a common problem: How does one make sure that only certain operations happen on one node at a time? … Continue reading →

The thoughtful bodepd has been kind enough to help me get my puppet-gluster module off the ground and publicized a bit too. My first few commits have been all clean up to get my initial hacking up to snuff with … Continue reading →

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…

I am an avid cobbler+puppet user. This allows me to rely on my cobbler server and puppet manifests to describe how servers/workstations are setup. I only backup my configs and data, and I regenerate failed machines PRN. I’ll be publishing … Continue reading →

Many thanks to johnmark in #gluster for syndicating my “gluster” tagged blog posts on http://www.gluster.org/blog/ I aim to keep these posts technical and informative, aimed mostly at other sysadmins and gluster users. Please don’t  be shy to comment on my … Continue reading →

I’ve been having some strange networking issues with gluster. “Eco__” from #gluster suggested I try an up to date Intel nic driver. Here are the steps I followed to make that happen. No news yet on if that solved the … Continue reading →

For the last ~two or so years I’ve played and tested gluster on and off and hanging out in the awesome #gluster channel on Freenode. In case you haven’t heard, gluster was acquired by RedHat back in October 2011. This post … Continue reading →

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…
