did you cat the file through the gluster mount point or on the 
underlying filesystem.
the auto-heal is automatically "activated"  but it only "heal's" on 
file access, so if you access the file through the gluster mountpoint 
it should find that it's out of date and update from one of the other servers.

check your gluster log. grep for your filename and see what it might 
say (on both servers)
