Hi,
im trying to get a client boot from my server via nfs. but it fails
with:
Root-NFS: Server returned error -93 while
mounting /nfs-exports/pxeclient
the client uses a vanilla 2.6.24.7 kernel with these settings:
<*> NFS file system support
[*] Provide NFSv3 client support
[*] Provide client support for the NFSv3 ACL protocol extension
[*] Root file system on NFS
[*] Support for rpcbind versions 3 & 4 (EXPERIMENTAL)
full config:
http://metalfan2.me.funpic.de/.config
kernel append line:
append root=/dev/nfs nfsroot=192.168.11.3:/nfs-exports/pxeclient ip=dhcp
the system successfully boots the kernel via syslinux and requests its
ip via dhcp
server:
rpcinfo -p localhost

well, some grepping in /usr/include/ came up with:
./asm-generic/errno.h:#define EPROTONOSUPPORT 93 /* Protocol not supported */
what's the server setup in this picture? and is that negative
error value getting propagated into userland, or is that just from a
kernel log?

The system doesnt start at all, it stops just before the root fs gets
mounted. before init runs.
what do you mean by server setup?

Error 93 is EPROTONOSUPPORT. Is there a firewall between client and
server? tcpwrappers on either end? Are you using a motherboard NIC
that silently hijacks a reserved UDP port?
Try capturing a network trace with "tcpdump -s0 -w /tmp/dump" on your
server while your client boots. Take a look at it with wireshark or
tethereal.

I believe that the default is to try mounting NFSv2, unless you
explicitly add the 'v3' option. Try something like
append root=/dev/nfs nfsroot=192.168.11.3:/nfs-exports/pxeclient,v3 ip=dhcp
Cheers

Okay, ive used the append line above and now it mounts the root
filesystem. But it takes ages, looks like the requests time out.
Theres no firewall between the server/client.
Heres a tshark capture(330Kbyte) from power on to mount root and some of
the following timeouts:
http://metalfan2.me.funpic.de/nfsd.capture2
ive used the filter !tftp and saved it

Got it running, finally. Thx to all, saved me a lot of trouble.
Ive changed the machine that serves the nfs-root and some other small
adjustments.
