When I use this option, and the file isn't available in "brick", does  
it automatically loads the file from a fileserver?

The glusterfs mounted directory is alwasys called "/srv".

On Fileserver 1:
I copy a file from a local disk ('/root' for exaple) to '/srv/xxx/ 
Doing it on console or per ftp its the same here.
Making a 'ls -lh /srv/xxx/' shows the new file.

On FIleserver 2:
Making a 'ls -lh /srv/xxx/' shows the new file.

On Webserver:
Making a  'ls -lh /srv/xxx/' the first time shows the new file.
Making again 'ls -lh /srv/xxx/' shows the old file :-(

The log on the Webserver says:
afr: self-healing file /www/XXXX/yyyyyyy.gif from subvolume brick to 2  

And now the old file ist now on the Fileserver again ... :-(

I hope this helps ...
