Hello,
(My apologies if you've already seen this.. it didn't seem to post..
and no.. I can't seem to shake the crack pipe today :-)
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!
