Ready-to-use NFS kernel
Attention: What ever you do, you do it on your own risk
Contents
Prerequisite
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:
http://downloads.buffalo.nas-central.org/Users/kenatonline/NFSKernel/install-nfs-kernel.sh http://downloads.buffalo.nas-central.org/Users/kenatonline/NFSKernel/nfs-kernel-feroceon-kw.tgz
If you want to use JFS as filesystem, load this file into the same directory:
http://downloads.buffalo.nas-central.org/Users/kenatonline/NFSKernel/jfsprogs.tgz
Connect to your Linkstation.
telnet 192.168.1.100
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 install-nfs-kernel.sh like this:
./install-nfs-kernel.sh
If no errors occur, cross your fingers and reboot.
reboot
If you want to double check, look for the kernel in /boot and for the modules in /lib/modules/2.6.22.18kenatonline. You should find this:
/boot: 2186080 Jan 31 13:28 uImage.buffalo
/lib/modules/2.6.22.18kenatonline:
4096 Jan 5 19:42 kernel
13959 Jan 5 19:42 modules.alias
69 Jan 5 19:42 modules.ccwmap
3921 Jan 5 19:42 modules.dep
73 Jan 5 19:42 modules.ieee1394map
141 Jan 5 19:42 modules.inputmap
81 Jan 5 19:42 modules.isapnpmap
74 Jan 5 19:42 modules.ofmap
372 Jan 5 19:42 modules.pcimap
43 Jan 5 19:42 modules.seriomap
3432 Jan 5 19:42 modules.symbols
36027 Jan 5 19:42 modules.usbmap
How to check the success?
After the reboot you can check your success.
Type this:
uname -a
It should return this:
2.6.22.18kenatonline #20 Fri Jan 1 12:53:39 CET 2010 armv5tejl unknown
Type this:
rpcinfo -p 127.0.0.1
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/nfs.sh 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.
Changes
2010.02.04: Missing "uname" result added to case statement in file /etc/init.d/usb.sh. If you downloaded the tar before or on February 4th, please download again and extract /etc/init.d/usb.sh to /etc/init.d/usb.sh or patch line 8 of the script to look like this (use an Unix editor): "2.6.22.7"|"2.6.22.18"|"2.6.22.18kenatonline")
2010.02.08: Unfortunately some script in INITRD restores the original usb.sh at bootup. I wrote a small script which gets called in sysinit.d and patches the usb.sh on bootup if necessary. If you downloaded the tar before or on February 8th, please download again and extract /etc/rc.d/sysinit.d/S88patch_usb.sh to /etc/rc.d/sysinit.d/.
