This definitely sounds 'nice'. I cannot say off the hand of how
easy/difficult/reliable it would be to depend on all stat(2) members, but I
too would surely like to schedule based on all of them. It would also be
nice if files could be rescheduled dynamically based on the the stat members
(move file when permission changes, when size changes). This would make
GlusterFS really powerful (in terms of acheiving your dream configuration).
We will consider your suggestion when we work on the switch feature.
