Hello

Today I was struggling whole day with making uboot load software via NFS. As it turned out it was Gentoo issue. Uboot uses NFSv2 over UDP so I added appropriate settings to config file

Code:
/etc/init.d/nfs
OPTS_RPC_NFSD="8 -V 2 -V 3 -V 4 -V 4.1 -u"
RPCNFSDARGS="8 -V 2 -V 3 -V 4 -V 4.1 -u"


I am using systemd so following gentoo wiki RPCNFSDARGS should be enough. However uboot was still displaying timeout message. Turned out nfs server is still runnning only vers 3 and 4 over TCP:

Code:
root@serwer /etc # rpcinfo -p
   program vers proto   port  service
    100000    4   tcp    111  portmapper
    100000    3   tcp    111  portmapper
    100000    2   tcp    111  portmapper
    100000    4   udp    111  portmapper
    100000    3   udp    111  portmapper
    100000    2   udp    111  portmapper
    100024    1   udp  47950  status
    100024    1   tcp  37547  status
    100005    1   udp  41994  mountd
    100005    1   tcp  50039  mountd
    100005    2   udp  46054  mountd
    100005    2   tcp  56253  mountd
    100005    3   udp  43955  mountd
    100005    3   tcp  35697  mountd

    100021    1   tcp  34331  nlockmgr
    100021    3   tcp  34331  nlockmgr

Manual update of service solved issue:

I also tried something better but didnt work:

Code:
root@serwer /etc # cat /lib/systemd/system/nfs-server.service
[Unit]
Description=NFS server and services
DefaultDependencies=no
Requires= network.target proc-fs-nfsd.mount
Requires= nfs-mountd.service
Wants=rpcbind.socket network-online.target
Wants=rpc-statd.service nfs-idmapd.service
Wants=rpc-statd-notify.service

After= network-online.target local-fs.target
After= proc-fs-nfsd.mount rpcbind.socket nfs-mountd.service
After= nfs-idmapd.service rpc-statd.service
Before= rpc-statd-notify.service

# GSS services dependencies and ordering
Wants=auth-rpcgss-module.service
After=rpc-gssd.service gssproxy.service rpc-svcgssd.service

[Service]
Type=oneshot
RemainAfterExit=yes
EnvironmentFile=/etc/conf.d/nfs <------------------------------------
ExecStartPre=/usr/sbin/exportfs -r
ExecStart=/usr/sbin/rpc.nfsd ${OPTS_RPC_NFSD} <------------------------------------
ExecStop=/usr/sbin/rpc.nfsd 0
ExecStopPost=/usr/sbin/exportfs -au
ExecStopPost=/usr/sbin/exportfs -f

ExecReload=/usr/sbin/exportfs -r

[Install]
WantedBy=multi-user.target


Anyway I think nfs-utils package need fix. Isnt it?

pablocool,

there's no need to change init scripts or Systemd configuration files. You can configure NFS server parameters in /etc/nfs.conf:

man nfsd wrote:
Many of the options that can be set on the command line can also be controlled through values set in the [nfsd] section of the /etc/nfs.conf configuration file.

man nfs.conf wrote:
nfsd: Recognized values: threads, host, port, grace-time, lease-time, udp, tcp, vers2, vers3, vers4, vers4.0, vers4.1, vers4.2, rdma.
