Hi!

Have a small gluster system (4 nodes), which was specified to use rdma.
I would like to have it only use tcp instead. Is there a preferred way
of doing this? Either by some kind of reconfigure, or, by reinstalling
gluster, BUT while still retainig the files on the bricks and then
"reload" them into the updated gluster (no rdma) - is this possible?

1. Stop and delete the rdma volume. Deletion of a volume just removes the configuration information - bricks and data therein would remain intact.

2. Create a new volume with the same bricks. Before that, you will need to clear extended attributes on the brick directories as Joe mentions here:
