Hi,

Adding [swift] to Subject line (not really sure if it is needed, but is 
supposed to make it easier for the right people to see the question)!


The question about handoff nodes is a good one - use the swift-get-nodes 
binary to see what the set of handoffs are (the output is quite verbose, 
but should be reasonably self explanatory). However swift is not 
limiteds to *just* the ones shown there - if they are unavailable (or if 
you have write affinity enabled) you may get objects placed on *any* 
available device not already holding a replica.


regards


Mark
