I am moving from bellow ring

    swift-ring-builder account.builder
account.builder, build version 23
262144 partitions, 1.000000 replicas, 1 regions, 1 zones, 4 devices, 0.00 balance
The minimum number of hours before a partition can be reassigned is 1
Devices:    id  region  zone      ip address  port      name weight partitions balance meta
             0     1     1       127.0.0.1  6012      sdb1 2000.00      65536    0.00
             1     1     1       127.0.0.1  6012      sdc1 2000.00      65536    0.00
             2     1     1       127.0.0.1  6012      sdd1 2000.00      65536    0.00
             3     1     1       127.0.0.1  6012      sde1 2000.00      65536    0.00

tp the following ring structure as a stepping stone to adding another zone and node. then increassing to 2 replicas, and so forth till i get 3 replicas setup.

Can i use the swift-ring-builder set_info to change my above ring to this ring IE ip addresses.

ready to add an extra node.

also is there away to see when replication has finished of partitions,

Questions is related to how do i tell when the ring replication has completed so i can update the next node in the ring? i think it is via reading the logs and waiting to see each rings replication start and then completed message is this correct?

Note i have done this late last night and it appears to have worked well. looking into this this morning.
