As reported yesterday I am still having problems with nfs on my cluster<br>
when I have never had nfs problems in the past. I have added the<br>
/etc/exports file and put all the nodes into the hosts file and added a<br>
line for portmap in the hosts.allow file and I still get errors on both<br>
sides of the equation.<br>
<br>
On the master portmap reports this when a node tries to mount the /home<br>
directory:<br>
<br>
portmap[3185]: connect from 192.168.1.12 to dump(): request from<br>
unauthorized host<br>
<br>
and in the /var/log/beowulf/node.# file I see:<br>
<br>
node_modprobe: installing kernel module: sunrpc<br>
node_modprobe: installing kernel module: lockd<br>
node_modprobe: installing kernel module: nfs<br>
mount: RPC: Unable to receive; errno = Connection refused<br>
Failed to mount 192.168.1.10:/home on /home.<br>
<br>
Now in my hosts.allow file I have "ALL: 192.168." and I have "PORTMAP:<br>
192.168." and in /etc/exports I have "/home node*(rw)" I also have an<br>
nfs line in the /etc/beowulf/fstab that says:<br>
<br>
$MASTER:/home /home nfs defaults 0 0<br>
<br>
<br>
What is wrong here? I have each node listed in the /etc/hosts file too<br>
and still nothing. Any ideas what might be causing this?<br>
