Restart NFS on Synology Diskstation DSM 6.2

I was having trouble mounting an NFS share from my Synology DS411j:

gareth: ~
$ showmount -e diskstation
showmount: Cannot retrieve info from host: diskstation: RPC failed:: RPC: Unable to send; errno = Bad file descriptor

I can access the NAS, so lets have a look at what it’s exporting:

gareth@diskstation:/$ showmount -e localhost
clnt_create: RPC: Port mapper failure - Unable to receive: errno 111 (Connection refused)

Strange. I tried rpcinfo:

gareth@diskstation:/$ sudo rpcinfo
rpcinfo: can't contact rpcbind: RPC: Remote system error - Connection refused

I’m wondering if an automatic update has borked NFS, so I’ll try restarting it:

gareth@diskstation:/$ sudo service --status-all
sudo: service: command not found

Okay, so I can’t restart using service. Nothing in the usual /etc/init.d either.

gareth@diskstation:/$ sudo ls -al /etc/init.d/
total 8
drwxr-xr-x  2 root root 4096 Feb 15  2012 .
drwxr-xr-x 48 root root 4096 Aug 20 21:24 ..

Wonder where the startup script is…

gareth@diskstation:/$ sudo find . -name *nfsd* -type f
# Loads of files…

/usr/syno/etc.defaults/rc.sysv/ looks promising; cating it confirms it looks like an init script.

gareth@diskstation:/$ sudo ./usr/syno/etc.defaults/rc.sysv/ restart
statd: no process found
mountd: no process found
idmapd: no process found
svcgssd: no process found
rpcbind: no process found

It worked!

gareth@diskstation:/$ showmount -e localhost
