Gluster users - Sep 2010 - strange owners issue? ownership reset by the other gluster node

I have a /shared/www/example.com directory, being set up on a mirrored 
glusterfs filesystem (two servers).

I have a /shared/www/example.com/images/ directory there, owned by 
root:root.


Now, I want the webserver to be able to write to this directory: simple, 
just make the webserver the owner:

server1# chown www-data:www-data images

server1# ls -ld images
drwxr-xr-x 2 www-data www-data 4096 2010-09-14 22:19 images


Let's see what server2 thinks about it:

server2# ls -ld images
drwxr-xr-x 2 root root 4096 2010-09-14 22:19 images


Oops, it's back to root!


Now, what does server1 show?

server1# ls -ld images
drwxr-xr-x 2 root root 4096 2010-09-14 22:19 images

As we can see, it's root again - ownership was reset, although I didn't 
use "chown root:root". As a result, the webserver can't upload
files
(or, any other process which would need a similar operation), although I 
initially did "chown www-data:www-data images" on one of the servers.



I'm using glusterfs 3.0.5 on Ubuntu 10.04.

Did you do the chown operation to the mounted gluster filesystem, or
to the exported by gluster filesystem on one of your storage bricks?

What I mean is, is /shared/www what is exported in your
glusterfsd.vol, or did you do mount -t glusterfs volfile /shared/www ?
