load balancing is checked-in in the latest patch 562, but i have not tested
it for performance. you can give "option read-schedule on/off" in
afr volume, by default it is on. If it is off, reads are done from first
child (the way it was done before)
But we were thinking "option read-node" would be better than
"option read-schedule on/off"
"option read-node <sobvol>" will read from that particular subvol
(this will help when that subvol is local storage)
"option read-node *" will load balance from all children.
So option is either * or one of the subvols.
default is "option read-node *"
What do you think about it?
Thanks
Krishna
PS striped read not done yet.
