[Gluster-devel] Disk power-saving friendliness

Does GlusterFS issue forced disk flushes? I find that if I put the 
server into "laptop mode" to conserve power by spinning down the disk 
writes still tend to wake them up. Are the any particular 
paramters/options that should be used in this mode to minimize disk 
wake-ups? Disable direct I/O? Does write-behind work for local disks? 
Any suggestions on this?
