Hello all,
I have a kernel crash when I mount an NFS volume using RDMA transport.
On client and server is installed Centos 6.6 kernel 2.6.32
-504.8.1.el6.x86_64
I use nfs v4
The client hangs if I execute
mount -t nfs -o rdma ib-server:/data /data
Server and client are connected throw Infiniband network and Qlogic
adapters.
Can you help me?

Please send out the dmesg at least.
You should try to report bug to distribution, or update to some new
stable kernel.

I assume you mean that the mount command hangs, not that
the whole client deadlocks.
Add "port=20049" to the mount options.

File a bug with your distributor. They should be able to
help you with triage steps.
