Raspbian + NFS

Raspberry

Install:

apt-get install nfs-kernel-server
nano /etc/exports

Once there, let's add:

/mnt/flash *(rw,sync)

Dont' forget to run exportfs!

Add New Services:

Here's the deal: rpcbind must run before nfs-server. But due to a bug... that's not the case. What happens if the sequence is not that?... simple! NFS is inaccessible.

In order to fix this, let's do the following:

cat >/etc/systemd/system/nfs-common.service <<\EOF 
[Unit]
Description=NFS Common daemons 
Wants=remote-fs-pre.target 
DefaultDependencies=no 

[Service] 
Type=oneshot 
RemainAfterExit=yes 
ExecStart=/etc/init.d/nfs-common start 
ExecStop=/etc/init.d/nfs-common stop 

[Install] 
WantedBy=sysinit.target 
EOF
cat >/etc/systemd/system/rpcbind.service <<\EOF 
[Unit] 
Description=RPC bind portmap service 
After=systemd-tmpfiles-setup.service 
Wants=remote-fs-pre.target 
Before=remote-fs-pre.target 
DefaultDependencies=no 

[Service]
ExecStart=/sbin/rpcbind -f -w 
KillMode=process 
Restart=on-failure 

[Install]
WantedBy=sysinit.target 
Alias=portmap 
EOF
