Yes I know I have been a bit quiet recently, the reason? I was working on a new version of the website. More than four years after my migration from Wordpress to Octopress I decided to move away from Octopress. Today the site has a new design with a brand new landing page and not so new but very similar design for the blog. In this article, I will quickly explain some of the reasons.
Ceph Jewel Preview: map RBD devices on NBD
Another feature preview for Jewel. NBD driver for RBD that allows librbd to present a kernel-level block device
Ceph Jewel Preview: Ceph RBD mirroring
The RBD mirroring feature will be available for the next stable Ceph release: Jewel.
Your first Ceph OSD backed by BlueStore with ceph-ansible
Jewel is just around the corner and the first release candidate just came out yesterday (tagged: v10.1.0). If you are not familiar with BlueStore yet, checkout my recent article: Ceph Jewel Preview: A New Store Is Coming, BlueStore.
Ceph Jewel Preview: a new store is coming, BlueStore
A new way to efficiently store objects using BlueStore.
Use Ceph Ansible to build and deploy Ceph from master branch
It is really easy with ceph-ansible to deploy a Ceph cluster from its bleeding edge version (github master branch).
Migrate Ceph cluster from one distro to another
One of the recent use case I had was to migrate an Ubuntu based Ceph cluster to RHEL. We had strict requirements and did not want to have any data being migrated. It is yet another beauty from Ceph and particularly OSDs, where they basically have the ability to run on any machines. Let’s say you have an OSD, you can pull out the disk and plug in on another machine seamlessly. The approach taken here was a bit different, but relies on this capability.
See you at the Open Compute summit
Next week I will be heading to San Jose to attend the OCP (Open Compute) Summit. I will be presenting and demoing my work on containerizing Ceph on OCP hardware :D. This event is really exciting as most (to not say all) of the biggest Open Compute representatives (Facebook, Quanta etc) will be there. So if you come by the Red Hat booth, don’t forget to say hi ;)
Ceph Ansible first release
Ceph Ansible started as a personnal project, the reason was simple I wanted to have an in-depth look at Ansible. Thus I immediatly thought, why not try to deploy Ceph with Ansible. Moreover, I have never been a huge of Puppet and ceph-deploy was a couple of months old, so to me Ansible was the right answer.
