[Cbe-oss-dev] Using nfs server to netboot PS3

[Dmitry N. Mikushin]

Hello,

My goal is to setup Playstation to run 2.6.25-14.108 custom BSC kernel
with pdt and other Cell server related modules included. With simple
installing this kernel on PS3 running Fedora, system won't boot due to
errors in loading ps3disk.ko, I think it's broken. I decided to
workaround this problem by performing netboot. I've setup tftp server
whose root contains vmlinuz-bsc and initrd-bsc from the BSC kernel
distro. Then, from petitboot I chose netboot and set its options to:

image= tftp://192.168.0.100/vmlinuz-bsc
initrd= tftp://192.168.0.100/initrd-bsc

then, what we have to provide in arguments?

root=/dev/nfs ip=any netroot=:

I tried to set ip=192.168.0.101 (ip, where nfs server is located) and
netroot=:/mnt (/mnt folder of server is mounted to nfs server).
After executing this option, kernel is able to start (i.e. tftp works
fine), but if fails to mount any kind of filesystem. I'm wondering, if
it is a problem of wrong options specified or misconfigured nfs
server.

When I try instructions from here
http://www.kernel.org/pub/linux/kernel/people/geoff/cell/ps3-howto/ps3-nfs-root-howto.txt
mount -o nolock 192.168.0.101:/mnt /remote
gives "mount: RPC: Unable to receive; errno = Connection refused",
however NFS seems to be working if I mount it to itself.

Kind regards,

D.
