Glusterfs

Volgen-2.0

Designing and prototyping volgen for GD2 I’ve recently begun working on volgen for GD2. This post gives an overview of what I’ve been doing till now.

GlusterD right now has hardcoded graph topologies in its code. This makes it very hard to begin modify graphs.

GlusterD Next Gen

I just presented a talk on GlusterD Next Gen / GlusterD-2.0 at the first ever Gluster Summit at Barcelona. I’m embedding the slide deck here for all to see.

Setting up network encryption in GlusterFS

Introduction GlusterFS has supported network encryption using TLS/SSL since GlusterFS-3.5.

When using network encryption, GlusterFS also uses TLS/SSL for authentication and authorization, in place of the home grown auth framework used for normal connections. Though encryption has been supported for quite some time, the number of users using it has been minimal.
