Hello,
  I am trying out the referral feature of nfsv4 but I am unable to succeed.

 This is what I did:
1. On fc-6 m/cs installed nfs-utils-1.0.11 and patched it with
nfs-utils-1.0.11-CITI_NFS4_ALL-1.dif.
2. Have 2 fc-6 (kernel- 2.6.18)m/cs out of which one is a server as well as
client(server1). While other is just the server(server2).
3. /etc/exports for server1:
/export
*(rw,fsid=0,insecure,no_subtree_check,sync,anonuid=65534,anongid=65534,nohide)
/export/etc
*(rw,insecure,no_subtree_check,sync,anonuid=65534,anongid=65534,nohide)
/exports/foo  *(fsid=2,insecure,no_subtree_check,nohide,refer=/foo@
server2.in.ibm.com)

4. A /export/foo directory exists in server1. And have mount-binded
/exports/foo on top of itself.

5. /etc/exports for server2:
/exp
*(rw,fsid=0,insecure,no_subtree_check,sync,anonuid=65534,anongid=65534,nohide)

6. On the client /etc/mtab :
/etc /export/etc none rw,bind 0 0
/export/foo /export/foo none rw,bind 0 0
server2:/ /mnt/nfs4 nfs4 rw,addr=9.182.193.96 0 0
server1:/ /mnt/NFS4 nfs4 rw,addr=9.182.193.206 0 0

7. the pseudo- file system on nfsv4 works fine. Only referral thing doesn't
work.

8. I have referred the following doc:
http://www.citi.umich.edu/projects/nfsv4/linux/using-referrals.html
    It mentions that  client 2.6.20. Is this the only concern?
