I am building a 4 node raspberry pi cluster,so one head node, and 3 compute nodes, following this tutorial: http://makezine.com/projects/build-a-compact-4-node-raspberry-pi-cluster/

And I am trying to use the NFS protocol to share data from a usb stick, what I found is that when I shutdown the pi's and start them the next day, I have to go to the head node and run:

   sudo systemctl restart nfs-kernel-server 

before I can mount the drive on the other nodes. Similarly, from the tutorial it was recommended to update the /etc/fstab file so that the drive is mounted when the node is started. But I'm finding that because I need to run the command above before I can mount the drive, it doesn't work. Does anyone have any suggestions about how to fix this problem?

As an update, I was asked to show the status after I had rebooted the system. I did find a warning that the portmapper was not running.

  • Post the result of running systemctl status nfs-kernel-server on the server. Note it's possible to check for any other failed services using systemctl status / systemctl (look for red highlighting in the latter).

  • before the manual restart of the service, obviouslly.

  • is rpcbind running? it needs to be, so if not that could be part of the problem. Jun 5, 2016 at 23:56

Google suggests this is a problem with some raspbian update.

if you look in dmesg / journalctl? This would be something to check for. I think you should have seen a similar indication if you thought to check the status of portmapper... if you knew that relevant service had been renamed to rpcbind :). (Although it should have shown up in the overall list of failed services which I suggested to check).

[    3.494252] systemd[1]: Found ordering cycle on basic.target/start

[    3.594361] systemd[1]: Job rpcbind.service/start deleted to break ordering cycle starting with basic.target/start

The last post in the thread is a nice hacky workaround.

It looks like another workaround would be to remove dhcpcd, if you don't need a dhcp client.

It looks the same as this Debian bug (believed fixed): https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=788191
