More Puppet Stuff
I’ve been continuing to migrate to my new server setup and Puppetising along the way, the outcome is yet more Puppet modules: The puppetlabs-firewall module performs very poorly with large rulesets, to work around this with my geoip/rirs module, I’ve … Continue reading
First thoughts and tips on EL 7
Generally one RHEL/CentOS/Scientific Linux (aka EL) release isn’t radically different to another, however the introduction of EL 7 is a bit of a shake up, introducing systemd, which means new init system, new ways of reading logs plus dropping some … Continue reading

Installing EL7 onto EL5 Xen hosts
With RedHat recently releasing RHEL 7 (and CentOS promptly getting their rebuild out the door shortly after), I decided to take the opportunity to start upgrading some of my ageing RHEL/CentOS (EL) systems. My personal co-location server is a trusty … Continue reading

Resize ext4 on RHEL/CentOS/EL
I use an ext4 filesystem for a couple large volumes on my virtual machines. I know that btrfs and ZFS are the new cool kids in town for filesystems, but when I’m already running RAID and LVM on the VM … Continue reading

gdisk, oh glorious gdisk
My file server virtual machine passed the 2TB limit a couple months ago, which forced me to get around to upgrading it to RHEL 6 and moving from MSDOS to GPT based partitions, as the MSDOS partitioning table doesn’t support … Continue reading
cifs, ipv6 and rhel 5
Unfortunately with my recent project enabling IPv6 across my entire personal server environment, I’ve bumped into a number of annoying issues – nothing that isn’t fixable, but things that are generally frustrating and which just shouldn’t be an issue. Particular … Continue reading
Largefiles strike again!
With modern Linux systems – hell, even systems from 5+ years ago – there’s usually very little issue with handling large files (> 2GB), in fact files considered large a decade ago are now tiny in comparison. However sometimes poor … Continue reading

mailx contains invalid character
Whilst my network is predominately CentOS 5 hosts, I’ve started moving many of them to CentOS 6, mostly on a basis of doing so whenever a host needs a particularly newer version, since I don’t really want to spend an … Continue reading
