Rebalancing two nodes simultaneously

[Lindsay Mathieson <lindsay.mathieson@xxxxxxxxx>]

If I have two nodes with identical drive/osd setups

Drive 1 = 3TB

Drive 2 = 1TB

Drive 3 = 1TB

All with equal weights of (1)

I now decide to reweight Drive 1 to (3).

Would it be best to do one node at a time, or do both nodes simultaneously?

I would presume that all the data shuffling would be internal to the nodes, so they would not effect each other.

NB. Drive 1 is rather slower than drives 2 & 3 which is why I did not reweight at the start, but we are running out of space (up to 84% on the 1TB drives)

p,s Is there a way to speed up the rebalance? the cluster is unused overnight, so I can thrash the IO
