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"/>
              <clusternode name="ha1" votes="1">
                              <method name="1">
                                      <device name="barriere" 
              <clusternode name="ha2" votes="1">
                              <method name="1">
                                      <device name="barriere" 
      <cman expected_votes="1" two_node="1"/>
              <fencedevice agent="fence_manual" name="barriere"/>
                      <failoverdomain name="mig_fod" ordered="1" 
                              <failoverdomainnode name="ha1" priority="2"/>
                              <failoverdomainnode name="ha2" priority="1"/>
                      <ip address="" monitor_link="1"/>
                      <nfsexport name="/usr/local/genome"/>
                      <nfsclient name="mig" options="ro,fsid=20" 
path="/usr/local/genome" target=""/>
                      <nfsclient name="mig213" options="fsid=213,ro" 
path="/usr/local/genome" target=""/>
                      <nfsclient name="mig217" options="ro,fsid=217" 
path="/usr/local/genome" target=""/>
              <service autostart="1" domain="mig_fod" name="nfs">
                      <ip ref=""/>
                      <nfsexport ref="/usr/local/genome"/>
                      <nfsclient ref="mig"/>

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