On the other hand, there is some value in thrashing your way through it manually the first time, especially with a small cluster like Duke is putting together. I'm a huge fan of automation and tools, in general, but... when it breaks, you have no clue what's wrong.
You can think of it as a week's worth of lab classes in cluster admin. (I went through a similar set of hassles trying to PXEboot a 4 node cluster over a wireless LAN.. It took me two weeks to figure it all out, but, boy, did I know a LOT more about Debian, NFS mounts, and how the boot process worked after that. ) Jim Lux -----Original Message----- From: beowulf-boun...@beowulf.org [mailto:beowulf-boun...@beowulf.org] On Behalf Of Tru Huynh Sent: Monday, November 19, 2012 5:05 AM To: Duke Nguyen Cc: Beowulf Mailing List Subject: Re: [Beowulf] PXEBoot struggling On Mon, Nov 19, 2012 at 03:43:48PM +0700, Duke Nguyen wrote: > Hi folks, > ... > After few days struggling with the system, here are what I have done: > * install SL6.3 on master node > * install DHCP server (using dhcpd) on master node > * install xinetd and enable tftp > * open firewall for tftp and dhcpd using iptables You could ease your way and try warewulf: http://hpc.admin-magazine.com/Articles/Warewulf-Cluster-Manager-Master-and-Compute-Nodes > > So to summarize: > * boot using liveCD -> OK, logging in fine > * boot using rsync of master node's system -> OK, cant log in SElinux is probably on the way, did you relabel? > * boot using rsync of client node's sytem -> cant boot you need to build/setup the boot from nfs on yur diskless clients. - do you have dracut-network installed (required for nfs booting) - pass the nfsroot flags to your client something like root=nfs:master:/nfsroot/c6 rw - fix /etc/fstab for / - fix /etc/sysconfig/network-scripts/ifcfg-eth0 ONBOOT=no # since you already have network Cheers, Tru -- Dr Tru Huynh | http://www.pasteur.fr/recherche/unites/Binfs/ mailto:t...@pasteur.fr | tel/fax +33 1 45 68 87 37/19 Institut Pasteur, 25-28 rue du Docteur Roux, 75724 Paris CEDEX 15 France _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
