We need an easy way to alter client configs without breaking DVM

It would be tricky in this version to achieve your requirements. Even though the filesystem supports different read-subvolumes for different clients, the CLI still does not have an interface to express this configuration to the filesystem yet.
With GlusterFS 3.1, I know how you can configure an environment with 3 replicas of files, but what is not clear to me is what the proper way is to configure GlusterFS clients to use this. I know you can use mount –t glusterfs server:/volname /mntpoint to mount the volume, but what happens when you have different clients that need to mount it in a different way. For example,
1. I have 3 replicas with 1 server on each rack in a datacenter.
2. I want to have the clients in a rack read data from a server in the rack and not from the other racks.
3. Since there is no ‘vol’ file, using the above mount command all servers in all racks will read from all racks.
In 3.0.x, you would specify the read-subvolume in the mirror volume definition on the client and then mount using the vol file. Is there a way of having multiple client configurations in 3.1.x? Or do I have to copy the vol file(/etc/glusterd/vols/volname/volname-fuse.vol) to the clients and mount things that way? If I do that, will it break DVM?

Planing to keep 3.4.x branch as "internal enhancements" release without any features. So moving these bugs to 3.4.0 target milestone.
makes sense mainly in community product... in RHS, this will be outside the supportable configuration... hence making it 'notabug'...
