[vox-tech] NFS Mounting Error

[Chris Jenks]

   Hello,

   I am trying to mount a NFS volume where both machines are on the same 
home network, but I get the following errors. From the client:

[root at pinky mnt]# mount -t nfs 192.168.0.14:/tmp /mnt/tmp
mount: 192.168.0.14:/tmp failed, reason given by server: Permission denied

On the server:

cruncher:/# tail /var/log/syslog
[...]
Dec  4 10:30:31 cruncher rpc.mountd: authenticated mount request from 
192.168.0.2:773 for /tmp (/tmp)
Dec  4 10:30:31 cruncher rpc.mountd: getfh failed: No such device

I haven't been able to find a single report of this type of syslog error. 
The server has a custom kernel, version 2.6.8, with the NFS server as a 
loadable module, and runs debian testing. Two different clients, with 
different kernels and different distros, gave the same error. Exports 
looks like:

cruncher:/# more /etc/exports
# /etc/exports: the access control list for filesystems which may be exported
#               to NFS clients.  See exports(5).
/var/cache/apt/archives 192.168.0.0/255.255.255.0(ro)
/tmp 192.168.0.2(sync,no_root_squash)

but exportfs -ra gives:

cruncher:/# exportfs -ra
exportfs: /etc/exports [3]: No 'sync' or 'async' option specified for 
export "192.168.0.0/255.255.255.0:/var/cache/apt/archives".
   Assuming default behaviour ('sync').
   NOTE: this default has changed from previous versions
192.168.0.2:/var/cache/apt/archives: No such device
192.168.0.2:/tmp: No such device

Restarting portmap, rpc.mountd, rpc.nfsd, rpc.statd and rpc.lockd don't 
correct the error. rpcinfo gives:

cruncher:/# rpcinfo -p
    program vers proto   port
     100000    2   tcp    111  portmapper
     100000    2   udp    111  portmapper
     100005    1   udp    820  mountd
     100005    1   tcp    823  mountd
     100005    2   udp    820  mountd
     100005    2   tcp    823  mountd
     100005    3   udp    820  mountd
     100005    3   tcp    823  mountd
     100024    1   udp    826  status
     100024    1   tcp    829  status

I don't know why nfsd doesn't show up. nfs-common and nfs-kernel-server 
are both installed on the server. Any ideas or suggestions would be most 
welcome.

   Thanks,

     Chris
