I just installed GlusterFS 3.1.3 on Arch Linux x86_64 with Kernel 2.6.28.2 and libibverbs 1.1.4. It's a 2 Node replicated setup over rdma: gluster> peer status Number of Peers: 1 Hostname: easyStor-252 Uuid: 6766b083-8a12-41a8-984e-dd3ca2f1c536 State: Peer in Cluster (Connected) gluster> gluster> volume info all Volume Name: Storage-1 Type: Replicate Status: Started Number of Bricks: 2 Transport-type: rdma Bricks: Brick1: easyStor-251:/var/export Brick2: easyStor-252:/var/export Options Reconfigured: auth.allow: 10.1.* gluster> When I try to mount using "mount -t glusterfs easyStor-251:/Storage-1 /mnt" I get no output. When I try to chdir to /mnt or call df the process hangs. Here's my logfile content: [2011-04-06 21:20:50.678395] W [io-stats.c:1644:init] 0-Storage-1: dangling volume. check volfile [2011-04-06 21:20:50.678516] W [dict.c:1205:data_to_str] 0-dict: @data=(nil) [2011-04-06 21:20:50.678545] W [dict.c:1205:data_to_str] 0-dict: @data=(nil) [2011-04-06 21:20:50.682292] C [rdma.c:3953:rdma_init] 0-rpc-transport/rdma: No IB devices found [2011-04-06 21:20:50.682371] E [rdma.c:4826:init] 0-Storage-1-client-1: Failed to initialize IB Device [2011-04-06 21:20:50.682397] E [rpc-transport.c:849:rpc_transport_load] 0-rpc-tr ansport: 'rdma' initialization failed pending frames: patchset: v3.1.3 signal received: 6 So it seems it can't find the IB device.

Would be great if someone can lead me to the right direction.
