Hello,
I've been working off and on on getting a cluster of 4.2-REL freebsd systems to
netboot, and am back to trying to get it running ..
I've dug through Alfred Perlstein and Matt Simerson's pages, but I'm afraid I'm
still doing something stupid that's preventing me from getting an nfs root to
mount. I know, booting x86 systems is a nightmare, but these systems will be
running in different locked lab environments, and swapping out one disk is MUCH
better than swapping out N (N=16/24/32) system disks ..
Currently I have one test system "crunch", the dhcp/boot server, and a client
system. We're using 3com 3c905c NICs with their latest MBA flash (4.30)..(the
cluster nodes have fxp's, but i'm hoping that pxe is pxe ..).. Pxeboot loads,
reads my loader.conf (where i have it loading nfs,null,mfs,if_xl modules..),
boots the kernel, then panics when it's unable to nfs mount root.. yet.. my
pxeboot is built using NFS to load the kernel (that part works)..
I've tried with a GENERIC kernel, as well as with BOOTP options (which seemed to
just make things worse..) I've popped my laptop on the net, retrieved an IP
from crunches dhcpd, and mounted 192.168.100.1:/d1/newroot to ensure that I
didn't hose up /etc/exports or something... I've also created a rootfs both by
dump/restore of a working system, and by installing from the 4.2R CD with a
different DESTDIR.. same issues. So far I'm ignoring swap until I can boot.
(Is this my stupid mistake?)
Here's what the failure looks like, my config files follow. This was typed, so
I annoted the stuff I skipped ...:

crunch:/d1/newroot/boot/loader.rc is the default loader..
Any ideas?
Thanks!
