Create and Configure Object Storage Rings

Rings connect the account, container, and object services. Rings also provide load balancing and failover for services that are running on multiple nodes.

Procedure

1. If you are logged out, log back in to the controller01 node.
   1. Using SSH, log in to the VMware Integrated OpenStack manager.
   2. From the VMware Integrated OpenStack manager, use SSH to log in to the controller01 node.
   3. Switch to root user.

      sudo su -

2. Create the account, container, and object rings.

   cd /etc/swift
   swift-ring-builder account.builder create 18 3 1
   swift-ring-builder container.builder create 18 3 1
   swift-ring-builder object.builder create 18 3 1

3. Add a storage device to each ring.

   swift-ring-builder account.builder add --region 1 --zone 1 --ip controller01_node_IP_address \
        --port 6002 --device sdb --weight 100
   swift-ring-builder account.builder add --region 1 --zone 1 --ip controller01_node_IP_address \
        --port 6002 --device sdc --weight 100
   swift-ring-builder account.builder add --region 1 --zone 1 --ip controller01_node_IP_address \
        --port 6002 --device sdd --weight 100
   swift-ring-builder container.builder add --region 1 --zone 1 --ip controller01_node_IP_address \
        --port 6001 --device sdb --weight 100
   swift-ring-builder container.builder add --region 1 --zone 1 --ip controller01_node_IP_address \
        --port 6001 --device sdc --weight 100
   swift-ring-builder container.builder add --region 1 --zone 1 --ip controller01_node_IP_address \
        --port 6001 --device sdd --weight 100
   swift-ring-builder object.builder add --region 1 --zone 1 --ip controller01_node_IP_address \
        --port 6000 --device sdb --weight 100
   swift-ring-builder object.builder add --region 1 --zone 1 --ip controller01_node_IP_address \
        --port 6000 --device sdc --weight 100
   swift-ring-builder object.builder add --region 1 --zone 1 --ip controller01_node_IP_address \
        --port 6000 --device sdd --weight 100

4. Verify the ring contents for each ring.

   swift-ring-builder account.builder
   swift-ring-builder container.builder
   swift-ring-builder object.builder

5. Rebalance the rings.

   swift-ring-builder account.builder rebalance
   swift-ring-builder container.builder rebalance
   swift-ring-builder object.builder rebalance

6. Ensure that the swift user owns all of the configuration files.

   chown -R swift:swift /etc/swift
