Eamonn O'Toole 3afab58fbd Place swift-servers in appropriate zones ... This change is backwards-compatible with existing yaml templates. We divide Swift servers among the number of zones set by the swift.zones metadata. Servers are placed in zones depending on their rank in the scaled-out list of Swift servers in the template used to build the overcloud stack. The scaleout rank N is: SwiftStorage|controller<N>. The appropriate zone is calculated as: zone = N % swift.zones + 1. The devices metadata which will be set in the overcloud yaml templates to enable the placement calculation will look like: r1z%<controller or SwiftStorage><N>%-<IP address>:%PORT%/d1 For example: r1z%SwiftStorage0%-<IP address>:%PORT%/d1 We anticipate that in future the zone placement algorithm itself will evolve.
