You can run your swift cluster with 2 replicas. This is set when the ring is first created. You can use `swift-ring-builder` (ie with no arguments) to get usage help. Note that there is not (yet) an easy way to change your replica count once the ring has been created.
If you have more than one drive for swift in each of your two machines, you can make three replicas. Swift will ensure that the two replicas on one machine are on different drives. --John On Nov 19, 2012, at 10:19 AM, Emilio García <emilio.gar...@cloudreach.co.uk> wrote: > Good day everyone, > > I want to set up a PoC for Swift.
