NFSv4 for dummies [SOLVED]

I have just replaced ubumtu 8.10 with archlinux i686 on my server (IBM X345) and now NFS has stopped working between my server and my desktop running Archlinux x86_64 installed amout a month ago.

On the both systems I carried over the working exports file and relevant parts of fstab.

Since installing arch on the server I have been unable to mount exports on either system.

On the server:

[root@fini]# mount /mnt/cave/data
mount.nfs: mount to server 'cave:/data' failed: RPC Error: Program not registered

On the desktop:

[mick@cave ~]$ mount /mnt/fini/data
mount.nfs: an incorrect mount option was specified

fstab snip:

fini:/data    /mnt/fini/data    nfs    rw,user,noauto,exec    0    0
fini:/cave    /mnt/cave/data    nfs    rw,user,noauto,exec    0    0

I've been reading the wiki ( http://wiki.archlinux.org/index.php/NFSv4 ) but  just get more confused with each reading.

Please help me

Re: NFSv4 for dummies [SOLVED]

That RPC Error seems to point to portmap not running or no entry in /etc/hosts.allow.

Re: NFSv4 for dummies [SOLVED]

after several hours of reading the nfs4 wiki and editing numerous files I was able to guess the right combination of options to make it work.


Now how do I flag this as solved?

Just edit your first post and change the title to "[SOLVED] NFSv4 for dummies".

Re: NFSv4 for dummies [SOLVED]

follow http://wiki.archlinux.org/index.php/NFSv4 with the exception of:

rpc_pipefs    /var/lib/nfs/rpc_pipefs rpc_pipefs defaults 0 0

in /etc/fstab, rpc_pipefs errors (not found) at boot

change:

Nobody-Group = nogroup

to

Nobody-Group = nobody

in /etc/imapd.conf

then triple check for tpyos

Here is the setup I have working:
desktop hostname is cave
server hostname is fini

/etc/fstab snip

#NFS exports
nfsd        /proc/fs/nfsd    nfsd    rw,user,nodev,exec,nosuid 0 0

/home        /srv/nfs4/home    none    bind
/srv/http    /srv/nfs4/http    none    bind

#NFS mounts
cave:/data    /mnt/cave/data    nfs4    rw,user,noauto,exec    0    0
cave:/home    /mnt/cave/home    nfs4    rw,user,noauto,exec    0    0
cave:/http    /mnt/cave/http    nfs4    rw,user,noauto,exec    0    0
