6. RAID on the storage drives is not required and not recommended, use a single partition per drive

On Swift Proxy Server:

7. please check http://rackerlabs.github.io/swift-ppc/, you should have at least 3 disks for the ring (my thought :))
cd /etc/swift
swift-ring-builder account.builder create 8 3 1
swift-ring-builder container.builder create 8 3 1
swift-ring-builder object.builder create 8 3 1
you should run above commands only once, so take care of the part_power value
Notes: checkhttps://swiftstack.com/blog/2012/04/09/swift-capacity-management/ for more info on weight, you can use disk capacity in GB for weight value during first initilization
swift-ring-builder account.builder add r1z1-192.168.20.40:6002/sdb1 25
swift-ring-builder container.builder add r1z1-192.168.20.40:6001/sdb1 25
swift-ring-builder object.builder add r1z1-192.168.20.40:6000/sdb1 25
swift-ring-builder account.builder add r1z1-192.168.20.40:6002/sdc1 25
swift-ring-builder container.builder add r1z1-192.168.20.40:6001/sdc1 25
swift-ring-builder object.builder add r1z1-192.168.20.140:6000/sdc1 25
swift-ring-builder account.builder add r1z1-192.168.20.40:6002/sdd1 25
swift-ring-builder container.builder add r1z1-192.168.20.40:6001/sdd1 25
swift-ring-builder object.builder add r1z1-192.168.20.140:6000/sdd1 25
Verify the ring contents for each ring (cd /etc/swift to run below commands):
swift-ring-builder account.builder
swift-ring-builder container.builder
swift-ring-builder object.builder
swift-ring-builder account.builder rebalance
swift-ring-builder container.builder rebalance
swift-ring-builder object.builder rebalance
