Barcamp Manchester

I’ve been meaning to write this post for some time, but things have been a little hectic recently. That said I really wanted to write something, even if it is a little short, about Barcamp Manchester. The event took place over the weekend of 18th & 19th October and was just a fantastic weekend. After a fairly decent break from the… Read more →

Gluster, CIFS, ZFS – kind of part 2

A while ago I put together a post detailing the installation and configuration of 2 hosts running glusterfs, which was then presented as CIFS based storage. http://jonarcher.info/2014/06/windows-cifs-fileshares-using-glusterfs-ctdb-highly-available-data/ This post gained a bit of interest through the comments and social networks, one of the comments I got was from John Mark Walker suggesting I look at the samba-gluster vfs method instead of… Read more →

Upgrade CentOS 6 to 7 with Upgrade Tools

I decided to try the upgrade process from EL 6 to 7 on the servers I used in my previous blog post “Windows (CIFS) fileshares using GlusterFS and CTDB for Highly available data” Following the instructions here I found the process fairly painless. However there were 1 or two little niggles which caused various issues which I will detail here. The… Read more →

Windows (CIFS) fileshares using GlusterFS and CTDB for Highly available data

This tutorial will walk through the setup and configuration of GlusterFS and CTDB to provide highly available file storage via CIFS. GlusterFS is used to replicate data between multiple servers. CTDB provides highly available CIFS/Samba functionality. Prerequisites: 2 servers (virtual or physical) with RHEL 6 or derivative (CentOS, Scientific Linux). When installing create a partition for root of around 16Gb,… Read more →

Normally I cover most of my projects on here but this one has been a little different as it was featured in this months Linux Voice magazine. For this very reason I won’t feature a write-up here, just a few images and videos… Read more →

Installing dig on a CentOS or Red Hat machine

Gone are the days where we install nslookup for DNS resolution testing, the new(ish) kid on the block is dig. Although maybe not installed by default, it can be installed quite easily from yum, however it comes bundled with a number of tools so the package name isn’t all that obvious. [root@server ~]# yum install bind-utils Will do the trick, now… Read more →

Import regular kvm image to oVirt or RHEV

I recently replaced a couple of servers within a friends business with an oVirt virtualisation setup, I’m really pleased with the whole configuration which consists of a single engine host and 2 hypervisor nodes, the storage is shared over the 2 hosts with glusterfs. The guests which run on the platform replace the services that ran separately on a couple… Read more →

2013 – A good year

I thought I’d finish off the year with a bit of reflection, overall it’s been a pretty good year in both camps of my life – the geek/tech and the family side. Obvious highs of the year include: Birth of my second child, Alfie. OggCamp 13 LinuxCon Europe Barcamp Blackpool RossLUGs 3rd year – some fantastic meetings this year. It… Read more →
