[Linux-cluster] strange GFS problem



I've a two node linux cluster.  Need to share 1 HD to
read/write simultaneously, from either box.  Should
either fail, I need the other to keep functioning.

I created 1 lvm on each server (changed lvm.conf as
per instructions).  Did gfs_mkfs -- no errors.  Ran
this (on each server)

> ccsd  
> cman_tool join 
> fence_tool join 
> clvmd           
> vgchange -aly   
> mount -t gfs /dev/gfs_vg/lvol0 /data

No problem.  Now, when I create a file on each server,
it doesn't appear on the other.  What's the deal?

(this is my cluster.conf:)
<?xml version="1.0"?>
<cluster name="acme_cluster" config_version="1">

  <cman two_node="1" expected_votes="1">
  </cman>

  <clusternodes>
    <clusternode name="10.1.1.1" votes="1">
      <fence>
        <method name="single">
          <device name="human" ipaddr="10.1.1.1"/>
        </method>
      </fence>
    </clusternode>
    <clusternode name="10.1.1.2" votes="1">
      <fence>
        <method name="single">
          <device name="human" ipaddr="10.1.1.2"/>
        </method>
      </fence>
    </clusternode>
  </clusternodes>

  <fence_devices>
    <fence_device name="human" agent="fence_manual"/>
  </fence_devices>

</cluster>

[root acmegrid1 data]# cat /proc/cluster/status 
Protocol version: 5.0.1

I'd really appreciate any help with this.  Thank you.
