While we’re still converting our puppet controlled infra to Ansible, we still have some nodes “controlled” by puppet, as converting some roles isn’t something that can be done in just one or two days. Add to that other items in your backlog that all have priority set to #1 and then time is flying, until you realize this for your existing legacy puppet environment (assuming false FQDN here, but you’ll get the idea):

So, as long as your PKI setup for puppet is still valid, you can act in advance, resign/extend CA and puppetmasterd and distribute newer CA certs to agents, and go forward with other items in your backlog, while still converting from puppet to Ansible (at least for us)

Mise en place d’une organisation DevOps Cyrille Le Clerc Comme le mouvement Agile a rapproché donneurs d’ordre et équipes de réalisation autour d’une vision commune orientée « produit », le mouvement DevOps rapproche aujourd’hui les équipes de développement (DEV) et d’exploitation (OPS) autour d’une vision commune orientée « service », afin de mieux concilier réactivité et qualité de service. DevOps aborde le paradoxe entre des équipes projets qui cherchent à livrer toujours plus fréquemment des nouvelles fonctionnalités d’une part et d’autre part des équipes d’exploitation qui cherchent à stabiliser et fiabiliser les systèmes tout en maitrisant leur coût.

J’utilise Backuppc depuis maintenant plus de 5 ans. Et je dois dire que je l’apprécie énormément… Difficile à mettre en place certes. Mais quelle liberté 😉 On peut lui faire faire ce que l’on veut. Le prix à payer est une prise en main parfois délicate, surtout pour ceux qui ne sont à l’aise avec le PERL.

Tech Recipe for Backuppc I will explain briefly how to move the Backuppc __TOP_DIR__ to another disk. The main reason of this long data processing is the performance improvement. I’ve tried several Filesystems and different under layer block device ( RAID5, RAID10) alwaysover LVM. For the moment the best seems to be RAID10 with 32K chunksize and a reiserfs filesystem mounted with (notail,noatime) options. The backup speed is not that much faster than on ext3 filesystem, but the main advantage of Reiserfs is that compare to ext3 the disk usage is reduced from 34G in ext3 to 27G in Reiserfs. The next step will be to test Btrfs performance but for that I first need to migrate from kernel 2.6.18 to 2.6.28 or higher 😉 So let start the recipe

Usefull vimdiff commands to view diff and merge October 15, 2008 @ 8:20 am · Filed under Linux Diffing the files and merging them is one of the very common task we do everyday.
