Ken,
There are basically two reasons why the root file system can fail to
NFS mount.
1) NFS isn't running correctly on the server. imho, NFS on Linux is
real flaky. The fact that you can do a ps and show that nfsd is running is
no indication as to whether NFS is actually working (which is unfortunate,
cause that should work). So, I would try to mount the /tftpboot directory
on the server itself, just to make sure NFS is happy, as in:
mount localhost:/tftpboot /mnt
If that fails, you need to restart NFS, as in: service NFS stop;service NFS
start ( I would recommend restarting, but stopping and starting seems to
work better when NFS is being flaky).
2) the network boot kernel fails to configure the ethernet device for
tcp/ip. Now, the bios on your client recognized the ethernet card and
configured it or the kernel would not have tftp'ed over. However, one of
the first things the kernel does is configure the ethernet device for
tcp/ip so you can do things like NFS mount the root file system. If NFS
is working, then the network boot kernel is not configuring your tulip
card, ethernet is not configured, and the NFS mount fails. So, where did
you get your network boot kernel, which one are you using? We might have
to rebuild the kernel for the latest tulip driver.

Subject: [Oscar-users] network installation
I am trying to get Linux Redhat 7.1 installed on my client nodes. I have
tried multiple possible configurations, from defining the clients, to using
an identical machine as the server and skipping steps 4&5. After step 6, I
insert my network boot floppy and boot up my first client machine.
Everything starts okay until the NFS tries to get going. I had a similar
problem when I used the kickstart file until I set up an NFS file system
myself. Any suggestions on what I'm missing?
Ken
My network devices are LNE100TX. The tulip drivers work on the server and
to network boot.
The following is a portion of my ouput where the installation stops:
scsi: 0 hosts
scsi: detected total.
3c59x.c 16Aug00 Donald Becker and others http://www.scyld.com/network/
pcnet32.c: PCI bios is present, checking for devices...
0 3c515 cards found.
cs89x0: no cs8900 or cs8920 detected. Be sure to disable nP with SETUP
IP-Config: No network devices available
Partition check:
hda: hda1 hda2 hda 3
Root-NFS: No NFS server available, giving up.
VFS: Unable to mount root fs via NFS, trying floppy.
