[Gluster-users] The strange behavior whose common denominator is gluster

[Ted Miller]

Are you sure you have mounted the gluster volume, and are writing to the 
gluster volume, and NOT to the brick?  What you describe can happen when you 
write to the brick instead of the gluster volume. You can see here: 
http://www.gluster.org/community/documentation/index.php/QuickStart in steps 
6 and 7.  If you do not understand the difference, include the output of the 
'mount' command from one of your servers.
