Today's Topics:
1. NFS-boot on PS3, kboot can't mount nfs-dir.s (gt bradley)
2. Re: nfs booting PS3, mount failed. (Geoff Levand)
3. Re: nfs booting PS3, mount failed. (Geoff Levand)
I'm trying to set up my PS3 to netboot (with an nfsroot).
I'm using instructions at
http://www.kernel.org/pub/linux/kernel/people/geoff/cell/ps3-howto/ps3-nfs-root-howto.txt
I've
passed section 3 (using tftp) to verify network /dhcp etc. (i.e. I'm
able to tftp-get a file to ps3 from kboot's ash shell (busybox).
i'm trying to mount the nfs server as per section 4. with
~# mount -t nfs -o nolock 192.168.99.1:/target /mnt/remote
I get the following error message:
mount: mounting 192.168.99.1:/target on /mnt/remote failed
if I boot the PS3 from the HD, then I am able to mount the nfs directory.
Using wireshark, I can see the initial dhcp traffic, (and when present the tftp
traffic).
the mount command doesn't open a network connection to the server,
So I have pretty much ruled out server
configuration.
running "strings" on the decompressed kboot image yeilds serveral nfs symbols,
so it
appears to still support nfs mounting. (using version kboot-20080609.bld from
geoff's dir at kernel.org)
I have tried googling, and searching the various mailing lists, but am stuck.
any help would be
appreciated

I forgot to mention an important point when using a rescue disk.
Most will mount all the runtime directories like /sys, /dev, /proc,
etc. onto the HD file system. Those directories should not be
mounted the when you make the HD root FS copy.
Either choose the rescue option to not mount the HD file system,
and mount it yourself later, or unmount all those directories.
Just use the 'mount' command to see what has been mounted on the
HD's root FS.

I have sometimes seen nfs problems with kboot. You could you
try petitboot. Get the latest 'experimental' one from here:
http://www.kernel.org/pub/linux/kernel/people/geoff/cell/ps3-petitboot/
Another thing to try is to use a 'rescue' disk/mode to copy the files.
Most distros have them. Fedora has a rescue mode in their installer:
http://download.fedora.redhat.com/pub/fedora/linux/releases/10/Fedora/ppc/iso/Fedora-10-ppc-netinst.iso
Just select 'rescue' instead of 'install', or you can add
these to the boot options: 'text rescue video=720p'.
You don't need kboot/petitboot to do nfs. To load the kernel
they just need to do tftp.

I'll try this this week-end, and let you know how it goes,
Thank-you for the quick response.
