nfs error messages and mountd fails

[François Patte]

Bonjour,

I try to have nfs working on a private network to allow some machines to
mount a directory from the server.

my exports file:

/home/guillaume   192.168.1.0/255.255.255.0(rw,no_root_squash,sync)

hosts.deny:

portmap: ALL
lockd : ALL
mountd : ALL
rquotad : ALL
statd : ALL

hosts.allow:

portmap: 127.0.0.1, 192.168.1.0/255.255.255.0 : allow
mountd : 127.0.0.1, 192.168.1.0/255.255.255.0 : allow
nfsd : 127.0.0.1, 192.168.1.0/255.255.255.0 : allow
statd : 127.0.0.1, 192.168.1.0/255.255.255.0 : allow
lockd : 127.0.0.1, 192.168.1.0/255.255.255.0 : allow

At nfs start-up:

kernel: NFSD: recovery directory /var/lib/nfs/v4recovery doesn't exist
kernel: NFSD: starting 90-second grace period
rpc.idmapd: nfsdreopen: Opening '' failed: errno 2 (No such file or
directory)

At nsf stop:

kernel: rpc.mountd: Caught signal 15, un-registering and exiting.
kernel: nfsd: last server has exited
kernel: nfsd: unexporting all filesystems
kernel: RPC: error 5 connecting to server localhost
kernel: RPC: failed to contact portmap (errno -5).

portmap is running

So sometimes (I don't know why!) mountd fails to start and the clients
cannot connect....

Thanks for help.

PS. I have a firewall on the server which allows everything on lo and
private network:

/sbin/iptables -A INPUT -i lo -j ACCEPT
/sbin/iptables -A OUTPUT -o lo -j ACCEPT

/sbin/iptables -A INPUT -i eth1 -s 192.168.1.0/24 -j ACCEPT
/sbin/iptables -A OUTPUT -o eth1 -d 192.168.1.0/24 -j ACCEPT

(eth1 is the private network interface)

I've seen that on all my PCs.  I don't know what the directory is
supposed to be for, but manually creating it got rid of those two
warnings.  I can see no difference in operation with or without it,
though.

Are you trying NFS4? You can only mount the root directory. I have
NFS firewalled (otherwise the following is insecure!!):

/ *.tqmcube.com(anongid=65534,no_subtree_check,no_root_squash,sync,insecure_locks,anonuid=65534,insecure,fsid=0,rw)

This requires nfs,rpcidmapd,  and portmap running

fstab looks like:
smtp:/                  /smtp                   nfs4    rw,rsize=32768,wsize=32768   0 0
