From time to time we need to upgrade our Jenkins installation. Usually this requires two restarts due to the fact that first Jenkins core needs to be updated and later on the huge amount of plugins. Of course you can update the plugins first and then core, but more often than not some plugins need a newer core version and therefore you don’t get the latest updates without upgrading core first.
To avoid starting Jobs starting jobs after the core upgrade we wanted to start Jenkins in…

From time to time one needs to count the size of all files matching a certain pattern.

This is just a quick post (merely to have something for myself to remember) on how to get MS SQL running on Linux.
As you might have noticed, there is a developer version of the next MS SQL server available (for now called “vNext Community Preview”) which is also available on Linux and even as a Docker container.

As announced in the previous post, I rebooted the blog in order to write about our experiences with OpenStack and Ceph. For the first topic I picked the Ceph cache tiering, as we have recently struggled quite a bit to keep it up and running ;)

It’s been a long time, but I figured it’s time to restart the blog. In the past two years we started setting up an OpenStack based IaaS for our developers to be able to test our software in a distributed fashion. As storage we’ve chosen Ceph which is quite powerful but also comes with a few unexecpted quirks. So expect quite some OpenStack and Ceph posts in the future.
