I made a little progress. Glusterfs appears to require /usr/local/etc/glusterfs/glusterfsd.vol. The compiled installation installs a sample file and documentation makes no mention of it. It seems that at least one parameter in the file, the path of the exported share must be given (and exist). This eliminates the errors about volume creation failing, although it doesn't actually succeed. Instead, it gives a different error: [rpcsvc.c:689:rpcsvc_program_actor] rpc-service: RPC program not available [server.c:428:server_rpc_notify] server: disconnected connection from 127.0.0.1:1022 It looks as if glusterfs wants at least parts of NFS to be running. However, turning them on and setting it to share the path I supplied to glusterfsd.vol) did not make a difference.
