Aggregated news from external sources
We spent some time this week working on our technical roadmap for the next few months. It’s all been mostly translated into issues and priorities in the tracker (here’s a sorted priority list), but from that level of gory detail it’s hard to see the forest for the trees. At a high level, the basic […]

I can’t decide whether Linus is amused or annoyed by the extent to which people hang on his every word, or go nuts over his random rants about this or that. People still talk about his pronouncement about O_DIRECT and tripping monkeys (which has now found a home on the open(2) man page). The latest […]

We’ve released 0.29.1 with a few fixes. The main thing is a fix for a
race condition in librbd that was biting people using rbd with qemu/kvm.
There was also a fixed memory leak in the OSD. The shortlog is below.

I tagged and uploaded v0.28 a week ago but forgot to blog and email about it. That may be just as well, as there were a number of issues that got fixed last week. I’ll separate out the main items. Changes for v0.28: osd: peering code refactor osd: long object name support osd: removed fragile […]
