[Gluster-users] hanging "df" (3.1, infiniband)

Lana - 
Can you try to mount locally on one of the servers, if that works please make sure that iptables is turned off on the client or that you have these chains in your firewall config -

It's CentOS 5.4 (the Rocks variant, technically). I have only tried 
installing the client software on one node so far, figuring that once 
I had it working and knew how I got to that state I could then install 
onto the rest. 

I did install all three of glusterfs-core, -rdma, -fuse RPMs on that node.
