Recently, I had a chance to think about an outage that I debugged and fixed a few years ago that involves Jenkins and systemd (or in this case lack thereof!). Generally, if you want to run a task at the end of every Jenkins job whether the job has passed or failed, you have two …Read more

We occasionally find leaks in Gluster via bugs filed by users and customers. We definitely have benefits from checking for memory leaks and address corruption ourselves.

There will most likely be a good reason why something is done in the way it is. This is just how things …Read more

Gluster has been taking big …Read more
