Hi guys,

I am implementing a two node cluster sharing via NFS, their local 
storage to one client.
At the moment, i am simulating a failover during a copy from the NFS 
server to the local client disk.

The first time i got a NFS file handle error. I tried to use a 
Filesystem ID (fsid) on the mount parameter of the client but now here 
is my issue:

[root@**** ****]# time cp 1Go.t* /usr
cp: reading `1Go.tyt': Input/output error


My cluster.conf :
<?xml version="1.0"?>
<cluster alias="mig_nfs" config_version="128" name="mig_nfs">
      <fence_daemon post_fail_delay="0" post_join_delay="3"/>

If you have any ideas or remarks, i would love to hear them. Thanks a lot.
