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

Hi,
I have read that if a primary node is unavailable for an
object PUT, the proxy will ask the ring for a handoff node and route
there instead. I am very interested to know the working of handoff nodes.
I would like to know the logic behind determining the location
of a handoff node. Does a ring have have a fixed set of handoff nodes
throughout its lifetime ? Is it a dedicated node used only for handoff
purposes ? If not how to determine whether a particular node can be
used for hand off purposes or not/
It would be very helpful if you could either elaborate or
provide links to articles explaining everything about hand off nodes.
Thank you.
