QNAP TS-509 & NetGear GS716T Port Trunk

I don't particularly need a 2GB trunk from the NAS but a recent switch upgrade to a NetGear managed switch, GS716T (which for £120 is bloody good value) gave me the option.

Set the NAS for bonded 802.3ad & created the LAG group on the switch.  Easy.

Two days later I noticed my Windows machines had lost their SMB mounts, Linux boxes all fine. Disabling one of the NAS bonded ports brought it all back.

I suspected some kind of ARP timeout.  Switched the LAG port from STATIC to LACP and all was well.  And has remained so.  No idea why Windows was FUBAR and not Linux and without cracking open Wireshark I can only guess.

Add a static route to QNAP NAS

Can't be done via the GUI so you need to use some CLI foo.  You can set a route temporarily via the shell but in order for it to remain persistent you need to edit the startup script.

1 - Connect via ssh to your device
2 - Mount the QNAP Configuration

The name of the actual device to mount depends on your model number. In general for x86-based systems this should be /dev/sdx6. For Marvell ARM based models it should be /dev/mtdblock5 or /dev/mtdblock4.

[~] # mount -t ext2 /dev/sdx6 /tmp/config

2 - Create or adapt autorun.sh

A shell script called “autorun.sh” will be executed by your QNAP storage system on every startup. It might be possible that file currently does not exist so just go ahead and create it with your favorite text editor, or the whatever is installed.

#!/bin/sh
route add -net <subnet> netmask <mask> gw <gw_ip_addr>

3 - Make sure that autorun.sh is executable
In order to be executable during startup, we will have to set the executable flag for “autorun.sh”:

[~] # ls -al /tmp/config/autorun.sh
-rw-r--r--    1 admin    administ       60 May 11 17:43 /tmp/config/autorun.sh*
[~] #
[~] # chmod +x /tmp/config/autorun.sh
[~] #
[~] # ls -al /tmp/config/autorun.sh
-rwxr-xr-x    1 admin    administ       60 May 11 17:43 /tmp/config/autorun.sh*
[~] #

4 - Unmount the config

[~]# Unmount /tmp/config
