obsolete with Firmware version: DSM 2.0-722

This is a guide on how to enable the NFS capabilities of the Synology product. This procedure is aimed for users who are experienced with Telnet and the Linux Operating System. Please note that improper manipulation or modification of the Synology server may result in machine malfunction or loss of data.

Please make sure that the Synology product has firmware 2.0.3 – 0518 or above, along with the Telnet service or SSH Service enabled. Both files can be found here.

Instructions for the NFS Server

Telnet into the Synology product and perform the following

Enabling Service

cd /usr/syno/etc/rc.d
mv S83nfsd.sh.sample S83****.sh
reboot (or /usr/syno/etc/rc.d/S83****.sh start)
vi /etc/exports

Note: * needs to be replaced with a number

Exports file

In the exports file, add the following line

e.g.: /volume1/upload 192.168.* (ro,root_squash,no_subtree_check)

Save the export file Check if the file /var/lib/nfs/rmtab does exist, if not, then run the following command:

touch /var/lib/nfs/rmtab

Now perform the following command

cd /
/usr/sbin/exportfs -a

Testing

Look at /var/log/messages to check whether the settings are ok with your Synology product

Instructions for Linux NFS Client

On your NFS client, perform the following to mount the NFS Server share

mount IP.of.Synology.NAS.Server:/volume1/upload /mnt

Note: /volume1/local/share/folder must exist locally, otherwise the mount will fail.

Notes

The NFS Service is disabled after every firmware upgrade.

The NFS mount is not shown in the web interface

Files saved on the Synology server are case-insensitive.

Supported versions:

NFS 2.0
NFS 3.0

MTU Jumbo frames

For some NFS clients (eg. TViX 6500/7000), errors are reported if jumbo frames are enabled. Mounting the NFS is possible: try disabling the jumbo frames setting in the Synology Disk Station Manager
