Hi, I'm running GlusterFS 3.3.1-ubuntu1~precise9 and I'm having some problems with the "rdma" and "tcp,rdma" options I hope someone can help me with. 1. What does "tcp,rdma" actually do - does it let you mix both types of client? (I did a few tests with iozone and found it gave identical performance to the "tcp".) 2. I can't get "rdma" to work, even in the simplest case with a single node. volume create storage transport transport rdma my_server:/data/area volume start storage mount -t glusterfs my_server:storage /mnt/storage The last line hangs. Looking in /var/log/glusterfs I can see the log for the volume: [2013-05-30 06:24:19.605315] E [rdma.c:4604:tcp_connect_finish] 0-storage-client-0: tcp connect to failed (Connection refused) [2013-05-30 06:24:19.605713] W [rdma.c:4187:gf_rdma_disconnect] (-->/usr/sbin/glusterfs(main+0x34d) [0x7f374d38a3ed] (-->/usr/lib/libglusterfs.so.0(+0x3bd17) [0x7f374cf23d17] (-->/usr/lib/glusterfs/3.3.1/rpc-transport/rdma.so(+0x5231) [0x7f3743398231]))) 0-storage-client-0: disconnect called (peer:) [2013-05-30 06:24:19.605763] W [rdma.c:4521:gf_rdma_handshake_pollerr] (-->/usr/sbin/glusterfs(main+0x34d) [0x7f374d38a3ed] (-->/usr/lib/libglusterfs.so.0(+0x3bd17) [0x7f374cf23d17] (-->/usr/lib/glusterfs/3.3.1/rpc-transport/rdma.so(+0x5150) [0x7f3743398150]))) 0-rpc-transport/rdma: storage-client-0: peer () disconnected, cleaning up This block repeats every few seconds - the line "tcp connect to failed" looks like it has lost the server name somehow?
