Regards Mario Just like any other port you install. you can either chroot into your diskless root filesystem (as I have it laid out, not you), and run the port tools. you can also run the package management tools. All programs are are files on the disk, there's no local registry as in windows to worry about. You can even compile on the diskless client. It just reads and writes files to the nfs server to compile ports. --TJ ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

[solved] Re: Re: Re: diskless - NFS root mount problem
Hi,
it turned out I was stupid enough to misconfigure the kernel...I forgot that I
had left the IPFIREWALL options turned on and as you know it's default to deny
so once the kernel initializes ipfw it blocks everything including NFS so that
was the whole problem...I removed the IPFIREWALL option and all went fine.
thanks again

Hi,
thanks again for your response:
here's what I have, what I do and what I want to happen
1. I have my desktop machine which is running FreeBSD-7.2-STABLE-amd64 from
June.
I created a new distribution like that (as shown in the handbook -
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/network-diskless.html):
mkdir /storage0/diskless
cd /usr/src
export DESTDIR=/storage0/diskless
make buildworld buildkernel installworld distribution installkernel
and created /storage0/diskless/etc/fstab with the following content:
192.168.0.1:/storage0/diskless / nfs ro 0 0
and I put this in /etc/exports (having in mind your advice about the group)
/storage0/diskless -maproot=0:0 -ro -alldirs 192.168.0.3
/usr -ro -alldirs 192.168.0.3
and this is in my dhcpd.conf (I tried with and without the comments - no
difference, same result)
host laptop {
hardware ethernet 00:1E:68:45:0D:98;
#option host-name laptop;
#ddns-hostname laptop;
#next-server 192.168.0.1;
fixed-address 192.168.0.3;
filename pxeboot;
option root-path 192.168.0.1:/storage0/diskless;
}
2. And I do this:
rpcbind
nfsd -u -t -n 4
mountd -r
/etc/rc.d/ineted onestart # I have my TFTP root set to /boot
/usr/local/etc/rc.d/isc-dhcpd onestart
then I start my laptop (which has a 64bit CPU therefore it should be
compatible with my amd64 kernel) enter the boot menu and choose the network
boot option and I can see that it acquires its IP address then fetches
pxeboot over TFTP then pxeboot loads the kernel and the kernel starts
bringing the system up...and these are the last few lines where the system
stops:
...
...
Trying to mount root from nfs:192.168.0.1:/storage0/diskless
NFS ROOT: 192.168.0.1:/storage0/diskless
nfs send error 13 for server 192.168.0.1:/storage0/diskless
bge0: link state changed to DOWN
bge0: link state changed to UP
3. What I want is to have a server that multiple clients can boot from
(diskless-ly as you say). And I want all file systems provided by the server
to be read-only (which means I don't need lockd, do I...)
Do you have an idea what could be my problem? ...obviously my TFTP and DHCP
services are fine, even the NFS as pxeboot is able to download the
kernel...maybe something in my distribution in /storage0/diskless is not OK?
thanks
mgp
Please compare my working configuration to yours to check. I found
lots of odd problems in your post and I thought it'd be best to just
run with this clean slate.
Network config:
One low-power PC Engines ALIX board running as the NFS server, with
a microdrive partitioned off for it's own system, plus a separate
mounted partition for diskless clients. This config works best with
one diskless client, and is not the documented way from FreeBSD
handbook to accomplish diskless workstations. I'll note what I
immediately saw as an error in your config during these snippets.
alix# bsdlabel /dev/ad0s1
# /dev/ad0s1:
8 partitions:
#size offsetfstype [fsize bsize bps/cpg]
a: 1048576 164.2BSD 2048 16384 8
c: 120001770unused0 0 # raw part, don't
edit
h: 10951585 10485924.2BSD 2048 16384 28552
alix# cat /etc/fstab

Ah, one of those moments. I have them too. Good to know it's working for you, and I would just because I'm the perfectionist personality type, change a couple of things that won't make a negative impact. The server's exports has no reason to export the diskless root with -alldirs. The system isn't asking for any mountpoint within / so you can leave off the -alldirs. 2nd, you buildworld and installworld into the diskless root, but never use it. You're using disk space you can reclaim. thanks again mgp snip Glad it's working, enjoy! ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
