Gluster users - Mar 2009 - Replicating data files is causing issue with postgres

We are attempting to run a postgres cluster which is composed of two  
nodes.
Each mirroring the data on the other. Gluster config is identical on  
each node:

volume posix
  type storage/posix
  option directory /mnt/sdb1
end-volume

volume locks
   type features/locks
   subvolumes posix
end-volume

volume brick
  type performance/io-threads
  subvolumes locks
end-volume

volume server
  type protocol/server
  option transport-type tcp
  option auth.addr.brick.allow *
  subvolumes brick
end-volume

volume gfs01-hq
  type protocol/client
  option transport-type tcp
  option remote-host gfs01-hq
  option remote-subvolume brick
end-volume

volume gfs02-hq
  type protocol/client
  option transport-type tcp
  option remote-host gfs02-hq
  option remote-subvolume brick
end-volume

volume replicate
  type cluster/replicate
  option favorite-child gfs01-hq
  subvolumes gfs01-hq gfs02-hq
end-volume

volume writebehind
   type performance/write-behind
   option page-size 128KB
   option cache-size 1MB
   subvolumes replicate
end-volume

volume cache
   type performance/io-cache
   option cache-size 512MB
   subvolumes writebehind
end-volume

The basic problem is whenever i try to import a database created on a  
different cluster i am running into these errors.

-bash-3.2$ pg_restore -U entitystore -d entitystore --no-owner -n  
public entitystore pg_restore: [archiver (db)] Error while PROCESSING  
TOC:
pg_restore: [archiver (db)] Error from TOC entry 1829; 0 147089 TABLE  
DATA entity_medio-canon-all-0 entitystore
pg_restore: [archiver (db)] COPY failed: ERROR:  unexpected data  
beyond EOF in block 77309 of relation "entity_medio-canon-all-0"
HINT:  This has been seen to occur with buggy kernels; consider

\002ns2.http://schemas.m..."

The issue seems to be related to using gluster, as when i attempt the  
same restore to local (non-replicated disk) it works fine.
Is there something amiss in our gluster config? Should we be doing  
something different?

Thanks for taking the time to read.

What does the client log say?
Which version are you using? If you're using any version < 2.0.0RC7,
could you please try with RC7 or later and see if the problem is still
there?
