[cNFS-Users] using dhcpd

[Philippe A. <phi...@fr...>]

Hello 

I am testing to make a small cluster with open mosix and clusternfs
Is it possible to use dhcp instead of bootpd ?
(I haven't found option in dhcpd doc for root=... option)

bye
thank

Should be. It depends on your kernel configuration. There is an option in
the kernel config where you could choose if it should try bootp, dhcp or
even rarp (IIRC). Check the kernel doco for details.
It's also a question if your network cards can boot with dhcp instead
of bootp.

BTW Why do you insist on bootp? Most recent DHCP servers can respond to
bootp queries as well...

hello
I don't want to use MAC addresses for my cluster so I need dhcp instead
bootp (all doc say that i need all mac addresses I want to put in the
cluster). It work well with dhcp and a range of IP addresses
thank you for your help

I'm not sure if I understand you correctly...

Are you saying that you don't know all MAC addresses of all nodes in the
cluster? That's not a problem - just instruct DHCP to use a range of
addresses and it will automatically distribute them over the nodes
regardless if the nodes ask via DHCP or BOOTP protocol. Usually DHCP
servers are so intelligent that they remember which address they gave to
which client and don't change it unless necesarry.

Antoher option is to use nodes with harddisks and boot from them - this
way you could configure the IP address on each node locally.

I have a feeling that you could use DHCP and the problems you are afraid
of come from a kind misunderstanding only. But I may be wrong ;-)

Anyway if you could come up with more details I'll try to provide further
help.
