Ocfs2 users - Nov 2009 - ocfs2_encode_fh:152 ERROR: fh buffer is too small for encoding

Hello,

We have one Oracle 10G R2 RAC production system, we installed OCFS2 on
both system and export ocfs2 filesystem via. nfs,  this export is
protected under oracle clusterware.

A few days ago, our system stop work and report corrupted file in nfs
filesystem.
I found below error in /var/log/messages.
-- Nov  7 10:03:24 dbu2pub kernel: (1751,3):ocfs2_encode_fh:152 ERROR:
fh buffer is too small for encoding

Could you help me? 
- What's meaning of this error?
- Does the error will corrupt file system under export ocfs2 via nfs?

I searched web but they are all about NFSv2, but we used NFSv3. So I ask
for your help. Thanks in advance.

Our environment,
      Red Hat Enterprise Linux AS release 4 (Nahant Update 6)
      2.6.9-67.ELsmp

      ocfs2-2.6.9-67.ELsmp-1.2.8-2.el4
      ocfs2-tools-1.2.7-1.el4
      ocfs2console-1.2.7-1.el4

BRs,
Colin

I doubt the two issues are related. I cannot see how unable to encode an 
nfs filehandle
can lead to a file corruption. Having said that, I am puzzled by that 
error. Is this is
one time thing or more often. If so, we could provide you with a debug 
version that will
dump more info.

As far as the corruption goes, I was to confirm that this is a file data 
corruption and not
a file system corruption? Do you know what the corruption is? Has anyone 
analyzed the data?
