Xilinx Zynq Linux – Mount NFS Volume, Connection Refused, failed to register lockdv1 RPC service (errno 111)

/2 Comments/in /by

You may have been having problems mounting an NFS volume on a Xilinx Zynq kernel build, perhaps mount fails with a ‘Connection Refused’ error message. If you check the /var/log/messages

cat /var/log/messages

Then you may see some entries like this:

Jan 10 21:22:34 zynq-zx3-starter user.warn kernel: svc: failed to register lockdv1 RPC service (errno 111).

If this is the case, then you may have to provide some extra option arguments to mount to get things working as follows:

 
mount -o port=2049,nolock,proto=tcp 192.168.0.11:/export /mnt/mymountpoint

I was having huge problems getting mount to work but this fixed things for me, thanks to all here for the tip!.
