Hi, 
I have installed glusterfs 1.3.8.pre1 (repository revision glusterfs--mainline--2.5--patch--676) on three severs under VMware.
This configuration (shown bellow) works just fine (HA, self-heal,...), but if I want to enable writeback and readahead options,  this configuration refuses to be loaded?! What is wrong in that case!?

Could someone, please, explain it to me, why is that so? I need this writeback and readahead options up and running so I can test the GlusterFS High Availability whith non-default parameters.

Oh! One more thing. Wahat is exactly the
option remote-host roundrobin.gluster.local for? How does it actually work?
It does not work as it is, so I had to comment it. :(
I have a feeling that my system would be much more faster if I manage to enable roundrobing on client side.

Best regards, 
Predrag BajiÄ?
