Antbird enables Hummingbird to use GlusterFS as storage backend over Libgfapi. This project aims to be Go implementation of SwiftOnFile project.
- Set up the hummingbird environment with SAIO as described here
- Use this branch to install hummingbird. This will make hummingbird pluggable.
- Create GlusterFS volumes and export it over libgfapi
- Install gogfapi:
go get github.com/kshlm/gogfapi - Add GlusterFS volume names to object ring as devices.
- Apply following diff to hummingbird code referred in Step 2:

It's helpful to see a trace of libgfapi calls made by hummingbird:
