In the documentation, http://www.gluster.com/community/documentation/index.php/Gluster_3.1:_gluster_Command it says there is a "set-transport" command: Transport Commands volume set-transport VOLNAME TRANSPORT-TYPE [TRANSPORT-TYPE] ... Set the transport type for the specified volume. I wanted to try converting from RDMA to TCP, so this seemed like what I wanted. However, when I try it on my 3.1.1 installation, I get: # gluster volume set-transport RaidData tcp unrecognized word: set-transport (position 1) It does not seem to be listed by "gluster volume help", either. I'm not sure whether this is a documentation bug or a bug in the "gluster" command. .. Lana (lana.deere at gmail.com)
