QNAP - Changing the NFS UDP "rsize" variable to 32K

[Drebin]

For the best performance, you can change the Mede8er NFS options to use "protocol = UDP" and "rsize = 32768".
Unfortunately, QNAP will ignore this and connect using "rsize = 8192".

This is easily fixed. There is a file on the QNAP called "udp_payload_size". It contains a single number "8192".
You will need to edit this file and change the number to "32768".

To do this, first download a program called "putty.exe" from here:-

http://www.putty.org/

It's a standalone exe file that doesn't need installing. Start the program and you will see this:-



Enter the ip address of your QNAP and click OPEN.
(The first time you may get a warning message. It's OK to continue.)

A terminal window will open and prompt you for your username and password.

To see the contents of the "udp_payload_size" file, enter this command:-

cat /proc/net/rpc/udp_payload_size
(right click if you want to paste things into the terminal window)

To change the contents of the "udp_payload_size" file to "32768", enter this command:-

echo 32768 >/proc/net/rpc/udp_payload_size

Type "exit" to close the terminal window.



Reboot the mede8er and it will now use the new block size for NFS/UDP connections.

after restart the qnap, the setting is gone.
Is it possible to change it when the qnap is booting ?

[Drebin]

Yes, I noticed it reverts back to 8192 when you re-boot the qnap.

To make it permanent, you can edit the following file:-

/etc/config/uLinux.conf

and add the UDP_PAYLOAD_SIZE to the NFS section so it looks like this:-

[NFS]
Enable = TRUE
UDP_PAYLOAD_SIZE = 32768

oh thx :-)

is there a manual to do this ?
unix isn`t my world.

I used the built in text editor "vi" to edit the file. It's not easy to use though.

I found this website helpful:-

thx now it works 

open terminal

type vi /etc/config/uLinux.conf

this opens the conf file

search for the [nfs] section

press "i" for insert
type UDP_PAYLOAD_SIZE = 32768
under the  "Enable = TRUE"

Hi guys
I'm Enrico From Italy

I have Qnap Ts 212
and i will buy MED600X3D (next Wednesday arrive )

I have entered in the file to make the changes suggested but could not find the section NFS
I also tried to enter command lines but I could not save the file

What should I do?

Thank you
Enrico

Turn on the NFS server so it creates its section in the config file.

I have new QNAP TS-451 and it has NFS enabled and everything works flawlessly but I still want to use 32k but this guide doesn't work for me.
I edited conf file and saved it and rebooted my nas.
Any idea how to make this work? See screenshots:

I have a QNAP 219p II and I can't seem to find the built in editor. Can someone point me in the right direction?

Did you start by running terminal?

open terminal

type vi /etc/config/uLinux.conf

this opens the conf file

search for the [nfs] section

press "i" for insert
type UDP_PAYLOAD_SIZE = 32768
under the  "Enable = TRUE"

press esc

type ZZ

The only thing here that I am unclear about is "open terminal". I don't know where to find it. I have looked all over the admin control panel and can't find a way to open a terminal.
