Rebalance has been immensely useful to us. When adding new storage
nodes, we are able to mitigate the damage from HD failures, are able
to add nodes more sparingly, and just generally balances out load
across storage nodes.
( 12 storage nodes, 6 drives each if it helps )

Hey,
Are there any of you out there who active use the existing
"rebalance"
feature and have measureable benefits from it? Please confirm that
you
aren't just running it because it felt like a good idea, and that you
actually get results from it?
I have a larger plan for rewriting rebalance by wiring it over the
new
drain code, but I can also just get the new drain code out very
quickly
which will fix many problems for many people.
However in the process I might disable/destroy the existing rebalance
code, and it'll stay that way until we can finish writing the
rebalance
stuff on top of it.
If there're enough complainers I'll try to not break the old code, or
just
wait until I can replace all of it at once...
Thanks,
