Hmmm, not quite. Users of gluster are actually faced with two options;
- install the oVirt management framework, just to configure gluster
- configure gluster by hand with the CLI and parallel ssh
To para-phrase the great Obi-Wan, "these aren't the tools, you're looking for"
So in true open source fashion, I sat down to see if I could write something that could help simplify this initial configuration step. One of the cool things about the gluster project these days is the gluster forge. This provides a melting pot for all manner of projects relating to open source storage and gluster, so it seemed a natural place for my project to find a home.
These were my goals;
- make a 'wizard' to guide the user through the initial configuration steps
- design the wizard as a web interface
- make the tool light-weight, with little or, ideally no external dependencies
- give it a modern look and feel, exploiting css3 or html5 features where it makes sense
- ensure configurations are consistent from the start
The project can be found on the gluster forge here
The features that have been implemented so far include;
- detection of glusterd nodes (to use to build the cluster)
- formation of the cluster
- distribution of ssh keys from a 'master' node to the other nodes
- detect eligible, unused disks on each node
- user selection of disks to use for gluster 'bricks'
- format and mount the disks across each node
I've created a screencast on youtube to show the interface being used to create a cluster.
There's still a fair amount to do, but for now it's in a state that others can poke a stick at and see if it helps them.
