Busybox encountered input/output error while mounting NFS to TMP file system

Error is as follows
< 4> svc: failed to register lockdv1 RPC service (errno 111).
< 4> lockd_up: makesock failed, error=-111

If I add nolock it will just return. But later copy file card dead. But it’s a little too much.

The mount -t NFS
& lt; 4> SVC: failed to register lockdv1 RPC service (110) errno.
the mount: mounting on/TMP/WRR failed: Connection timed out

Maybe this error is related to Nfs server permissions, so add the no_root_squard parameter to the server. To continue. There’s still a mistake.

Because the NFS server factor is excluded, then mount is fine (because it’s a little copier). So this is a story that has nothing to do with servers and mounts.

See on the English post (http://forums.xilinx.com/t5/Embedded-Linux/nfs-mount-problem-on-microblaze/td-p/153272)
Something is not running on the Busybox file system. Some additional parameters need to be added.
The mount -o port = 2049, nolock, proto = TCP -t NFS
It worked. The magic parameters are in port and proto= TCP. The exact cause is unknown.
