Description of problem:
I have setup a 4 node cluster with gfs (AS4, Cluster Suite4, GFS 6.1).  I have 
3 gfs partitions that I am trying to export via nfs. This has been done and I 
can mount them on another redhat AS3 box. When I move the nfs shares to other 
nodes to simulate a failover I get stale nfs handle errors on the client 
machine

Upon investigation I found a article for cluster suite 3, about setting FS for 
nfs shares as these need to be the same for each node.  This seems to have 
been removed (the ability to set options, through the gui), but the 
documentation states that clurmtabd should handle this.

I have run cat /var/lib/nfs/rmtab on all the nodes when it is working (before 
the move and after, when I am getting the stale nfs handles) and the numbers 
are  not similiar or consistant across the nodes. NOTE- I am making assumption 
the numbers in these files are the FS numbers.

I have checked the major minor numbers for all the base devices (lvm 
partitions) and they are the same on all the machines!

here is an example output pre move

forall cat /var/lib/nfs/rmtab \; echo 
172.20.0.0/16:/mnt/gfs/lv1:0x00000014

Version-Release number of selected component (if applicable):
rgmanager-1.9.34-1

How reproducible:
everytime

Steps to Reproduce:
1.start cluster
2. mount nfs exports
3. move nfs export to new node
 
  
Actual results:
I get nfs stale locks on the client machine

Expected results:
the nfs shafre should seemlessly failover to new node
