Could that be a problem?

Me again. I have a small cluster with some scientific apps (gaussian, crystal, etc). The version installed in the past are ubuntu 7.04, and me, a smart guy, updated to 7.10, 8.04 and finally 8.10. Are everything is ok at users start to use the cluster again. The configuration of cluster is a one server and eleven clientes with two directories exported via NFS and NIS autentication between they. The options in /etc/export are: /home 192.168.1.0/255.255.255.0(rw) /usr/local/cluster 192.168.1.0/255.255.255.0(ro) And in /etc/fstab in clientes are: ladao:/home /home nfs tcp,sync,noatime,nodiratime,rw 0 0 ladao:/usr/local/cluster /usr/local/cluster nfs tcp,sync,noatime,nodiratime,ro 0 0 But, when i have a existent arch created inside /home directory in server and try edit this arch in exported /home directory in client occour a permission error. Extrange, cos, if i try only create a arch in client, the arch are created. Thinking that, the permission to write in this directory are correct. look: server: erik@ladao:~$ ls -lnad . drwxrwxrwx 9 1000 0 824 2009-04-08 10:30 . client: erik@diomedes:~$ ls -lnad . drwxrwxrwx 9 1000 0 824 2009-04-08 10:30 But, this is the problem: erik@diomedes:~$ touch teste1 erik@diomedes:~$ echo "aa" >> teste1 erik@diomedes:~$ more teste1 aa erik@diomedes:~$ echo "a" > teste1 - -bash: teste1: Invalid argument erik@diomedes:~$ more teste1 erik@diomedes:~$ The archive are recreated, but cleaned. Then, when the programs, that user are using try to edit and acces the archies, this programs, don't work correctly. PLEASE, SOME LIGHT HERE.
