Mounting drives [rpcbind]

Sat May 21, 2016 8:16 pm


i am building a cluster of pi's,

i am using "sudo service rpcbind start" and "sudo update-rc.d rpcbind enable" , to set mount drives and auto update on reboot. but this commands are not working.
the tutorial i am following is for prior version of rpi-2 i believe.

Nobody uses NFS these days it seems :)

I just had to install nfs-kernel-server on a Pi 3 and got into the issue where mounts from remote hosts fail until you've restarted nfs-common (and perhaps nfs-kernel-server ?) meaning there is a freaking boot order problem in systemd.

Turns out that 2 years ago a nice guy had it all sorted out but his solution is still not applied to standard installs.
The mailing-list post is spot-on except for the temporary files business "Created my own /etc/tmpfiles.d/rpcbind.conf"; This dir doesn't exist on my Pi. I disregarded this part and it seems to work perfectly fine.

If you want to stay on this forum, this is what I just tried:
1) Boot (raspbian-lite, current) and try to mount an export from another host: no joy.
2) On the Pi, add:
2.a) /etc/systemd/system/nfs-common.services

Code: Select all

Description=NFS Common daemons

ExecStart=/etc/init.d/nfs-common start
ExecStop=/etc/init.d/nfs-common stop

2.b) /etc/systemd/system/rpcbind.service

Code: Select all

Description=RPC bind portmap service

ExecStart=/sbin/rpcbind -f -w

3) Run "systemctl enable nfs-common" and "systemctl enable rpcbind"
4) Reboot and try to mount an export from another host: works.

You have to only have the Boot Loader on the SD card, and the OS on the USB pocket drive. It will never work with just using thr SD card.
