Direct NFS problem in 11g

I have an unsupported environment running:
CentOS 4.4 in VMWare Server 1.x (2 of these)
RAC 11.1.0.6.0 (production release, not beta)
OpenFiler 2.2 serving NFS (running in a 3rd VM)

These VMs are all running on the same server (it has 16Gb of RAM and plenty of 
CPU) and they're all running fine. 

So, many have done this and it is working just fine. I'm trying to play with 
the Direct NFS features and I know a few of you have tried this as well. 

I've created an $OH/dbs/oranfstab with:
server: openfiler1
path: 172.16.163.200
export: /mnt/danrac/of1/all1 mount: /mnt/all1

server: openfiler1
path: 172.16.163.200
export: /mnt/danrac/of2/all2 mount: /mnt/all2

and they're mounted fine:
Filesystem           1K-blocks      Used Available Use% Mounted on
172.16.163.200:/mnt/danrac/of1/all1
                      10321216    256768   9540160   3% /mnt/all1
172.16.163.200:/mnt/danrac/of2/all2
                       5039616    141248   4642368   3% /mnt/all2

I also changed the libodm11.so pointer to reference the NFS library per the 
instructions. 

I created a tablespace using this new filesystem by placing a file on /mnt/all1 
and now I see this message in the alert logs of each instance:
Direct NFS: mount complete dir /mnt/danrac/of1/all1 on openfiler1 path 
172.16.163.200 mntport 741 nfsport 2049
Direct NFS: mount barrier to server openfiler1 failed

Have any of you seen this before or have any suggestions? Obviously, Metalink 
isn't quite ready to return search results for this new feature.
