and board ip
under the correct circumstances have occurred ERROR:File lookup fail
, that is, find the file failed. How can we solve it?

file among the servers.
Solution
Let Ubuntu compatible V2 version, which is modified /etc/default/nfs-kernel-server

# Runtime priority of server (see nice(1))
RPCNFSDPRIORITY=0
# Options for rpc.mountd.
# If you have a port-based firewall, you might want to set up
# a fixed port here using the --port option. For more information,
# see rpc.mountd(8) or http://wiki.debian.org/SecuringNFS
# To disable NFSv4 on the server, specify '--no-nfs-version 4' here
RPCMOUNTDOPTS="--manage-gids"
# Do you want to start the svcgssd daemon? It is only required for Kerberos
# exports. Valid alternatives are "yes" and "no"; the default is "no".
NEED_SVCGSSD=""
# Options for rpc.svcgssd.
