Gluster users - Apr 2011 - Editing text files on NFS mounted volumes

Hello list-
I have a strange problem opening text files on NFS mounted volumes with 
certain text editors.  With nedit and gedit I get the error "Could not 
open file" or similar, and kwrite just show an empty file.  Other 
editors such as emacs, vi, mousepad (XFCE4 desktop) and kedit (simple 
KDE editor) work fine.  The problem is that nedit, gedit and kwrite are 
the ones most people want to use.  None of the editors have any problems 
opening files on native GlusterFS mounts, but I only use the GlusterFS 
client on our compute servers and I don't want to have to install it on 
all the office PCs.  Does anybody know why this problem occurs with NFS 
or how to stop it?

-Dan.

Do you know if the nedit, gedit and kwrite editors use extended file system
attributes? Could it be some kind of collision with GlusterFS using the same
ones?

Just a shot in the dark.

i have also seen this too.  even with vi!  and nothing in the log.  i'm in a
crunch period right now - so have not had a change to investigate further.
 anyone else out there seeing this?  it's scary...

i'm running:  3.1.3 glusterfs on 4x opensuse bricks.  dist-repl.  nfs &
glusterfs fuse clients.

Try catting a file from the shell. I'd like to see the error message 
printed by a shell tool to see whats going on. Thanks.
