Sharing directories with NFS
 
Hope someone can help me out with this problem I'm having with NFS.

I have a machine running FC4 and for some reason I can't get it to export a filesystem. In my /etc/exports file I have
Code:
/paddy 192.168.0.0/24(rw,sync,nohide,no_root_squash)
I then run
Code:
exportfs -r
but the file doesn't get exported ie it doesn't show up when I run
Code:
exportfs -v
It's really strange because there are no error messages in /var/log/messages and I have it working perfectly on another FC4 machine. Anyone have any ideas what could be causing this?

I'll ask the obvious questions...

Do you have nfsd, portmap, rpcimapd, mountd and so on enabled? Are you sure the network address is correct (and not, say, 192.168.1.0)?

Thanks yes I m sure I have the ip address right because I can share a directory on computer A and mount it on computer B but I can't get it to work in the other direction! I have all the correct services running but I have just noticed this error in the output of dmesg.

nfsd: unexporting all filesystems
RPC: failed to contact portmap (errno -5).
nfsd: last server has exited
nfsd: unexporting all filesystems
RPC: error 5 connecting to server localhost
RPC: failed to contact portmap (errno -5).

Any ideas? The portmap service is defo running

Is a firewall on computer A active? (/sbin/iptables -L)

Have you modified selinux to enable nfs sharing? (man nfs_selinux)

Just got it working myself
 
I just barely got NFSv4 working on Fedora Core 3, two commands are really usefully when troubleshooting

1. rpcinfo -p ( see nfs services )
2. netstat -tupa ( see active connections and listening ports ).
I run these on both sides to make sure the server is listening and that the client sent its connection request when doing a mount command.

This site is a walkthrough for Gentoo, but it worked for my on Fedora ( except for the Firewall part ) - http://gentoo-wiki.com/HOWTO_Share_Directories_via_NFS

Bon Chance!

Thanks for the help, there is no firewall on either computer but I haven't done anything with selinux. I think I might have to have a read up about that. I know on computer b I turned it off completly when I was installing fedora so that would explain why computer b works ok!

Got it working, wohoo! Selinux was enables on machine b.

Thanks for the help again,
Paddy
