Part one, take the first full backup. At the present time, this code is still under development and should not be used on a production machine. However, I am posting it here for reference.

Eventually, this code is going to be included in a backup client I am developing that will interface with glusterfs and Amazon S3 storage.

Currently, this code is tested to run on Python v2.7.4 on a Fedora 18 machine. With all three python files, and any number of properly defined job xml files in the jobs.d/ directory, these scripts are currently functional.

I’ve been playing around with the latest stable release of GlusterFS, currently 3.3.1, for the last couple of weeks.  GlusterFS is a scale-out cluster storage system that is extremely easy to setup and get running.  However, during my short time working with it, I’ve stumble across a few items that were a little tricky to solve, and not well documented in the FAQ or elsewhere (that I found).

Problem: Attaching a Peer

The first problem I ran into was the inability to successfully attach a peer.  After running gluster peer attach gluster-node2 I would receive “Probe unsuccessful” “Probe returned with unknown errno 107″  Suffice to say that when an application gives you an “unknown error” it is very demoralizing.  Especially if you read Gluster’s documentation about how easy it is to setup.  If you check in /var/log/glusterfs/etc-glusterfs-glusterd.vol.log you can generally find some text that points to the problem.
