Greetings!
I'm testing a failover solution for NFSv4 on RHEL6 with latest updates.
My script umounts (umount -lf /share) the faulty NFS share if it sees that's hanging on the client (the NFS daemon is down on the NFS server) and it mounts the share from another healthy NFS server.

NAME
rping - RDMA CM connection and RDMA ping-pong test.
SYNOPSIS
rping -s [-v] [-V] [-d] [-P] [-a address] [-p port]
[-C message_count] [-S message_size]
rping -c [-v] [-V] [-d] -a address [-p port]
[-C message_count] [-S message_size]
DESCRIPTION
Establishes a reliable RDMA connection between two nodes using the librdmacm, optionally performs RDMA transfers between the nodes, then
disconnects.
OPTIONS
-s Run as the server.
-c Run as the client.
-a address
On the server, specifies the network address to bind the connection to. On the client, specifies the server address to connect to.
-p Port number for listening server.
-v Display ping data.
-V Validate ping data.
-d Display debug information.
-C message_count
The number of messages to transfer over each connection. (default infinite)
-S message_size
The size of each message transferred, in bytes. (default 100)
-P Run the server in persistent mode. This allows multiple rping clients to connect to a single server instance. The server will run
until killed.
NOTES
Because this test maps RDMA resources to userspace, users must ensure that they have available system resources and permissions. See the
libibverbs README file for additional details.
