Ready-to-use NFS kernel

Attention: What ever you do, you do it on your own risk

Do not use this kernel for firmwares > 1.24!


You have to have firmware 1.20 already installed and opened for telnet access, because the kernel is build from the Buffalo sources of firmware 1.20. If not, you can find a guide here: Open Stock Firmware LS-XHL

You have to have optware already installed, because you will need the package portmap and the package e2fslibs from the current optware feed. If not, you can find a guide here: Ipkg on the Linkstation (for end-users)

How to install the NFS kernel

Download this files into a directory of your Linkstation:

If you want to use JFS as filesystem, load this file into the same directory:

Connect to your Linkstation.


Switch to user root (and do not forget to load the profile (that's the reason for the "-")!)

 su -

Switch to the directory where you stored the files (for this example share "share" is assumed).

 cd /mnt/disk1/share

Start the script like this:


If no errors occur, cross your fingers and reboot.


If you want to double check, look for the kernel in /boot and for the modules in /lib/modules/ You should find this:

How to check the success?

After the reboot you can check your success.

Type this:

 uname -a

It should return this: #20 Fri Jan 1 12:53:39 CET 2010 armv5tejl unknown

Type this:

 rpcinfo -p

It should return something like this:

  program vers proto   port
   100000    2   tcp    111  portmapper
   100000    2   udp    111  portmapper
   100003    2   tcp   2049  nfs
   100003    3   tcp   2049  nfs
   100021    1   tcp  52992  nlockmgr
   100021    3   tcp  52992  nlockmgr
   100021    4   tcp  52992  nlockmgr
   100003    2   udp   2049  nfs
   100003    3   udp   2049  nfs
   100021    1   udp  32780  nlockmgr
   100021    3   udp  32780  nlockmgr
   100021    4   udp  32780  nlockmgr
   100024    1   udp  32782  status
   100024    1   tcp  59705  status
   100005    1   udp    369  mountd
   100005    1   tcp    369  mountd
   100005    2   udp    369  mountd
   100005    2   tcp    369  mountd
   100005    3   udp    369  mountd
   100005    3   tcp    369  mountd

Type this:

 /etc/init.d/ status

It should return this:

 portmap is running.
 mountd is running.
 nfsd is running.
 statd is running.
 lockd is running.
 All kernel NFS services running.

What is left to do for you?

You have to configure the exports. Look here for a guide: NFS for Beginners.

Is this kernel also available for the LS-CHLv2?

The LS-CHLv2 has the same kind of CPU but slower clock frequency and less RAM. The kernel source is identical and therefore this kernel should work for the LS-CHLv2 as it is for the LS-XHL. Unfortunately I do not know anyone who has a LS-CHLv2 to verify this. If you tried it successfully, report your success in the forum please.


2010.02.04: Missing "uname" result added to case statement in file /etc/init.d/ If you downloaded the tar before or on February 4th, please download again and extract /etc/init.d/ to /etc/init.d/ or patch line 8 of the script to look like this (use an Unix editor): ""|""|"")

2010.02.08: Unfortunately some script in INITRD restores the original at bootup. I wrote a small script which gets called in sysinit.d and patches the on bootup if necessary. If you downloaded the tar before or on February 8th, please download again and extract /etc/rc.d/sysinit.d/ to /etc/rc.d/sysinit.d/.
