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

[Lana Deere]

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.
