Swift Ring 配置錯誤修正

1. 查看 container.builder，其中前二項 ip address 錯誤為 192.168.122。
   

   [root@kvm4 ~(keystone_admin)]# swift-ring-builder /etc/swift/container.builder
   /etc/swift/container.builder, build version 4
   512 partitions, 2.000000 replicas, 1 regions, 2 zones, 4 devices, 100.00 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     192.168.122  6001      z1d1 100.00        512 100.00 
                1     1     2     192.168.122  6001      z2d1 100.00        512 100.00 
                2     1     1   192.168.122.4  6001      z1d1 100.00          0-100.00 
                3     1     2   192.168.122.4  6001      z2d1 100.00          0-100.00
   

2. 刪除錯誤的兩項，移除時系統提醒要做 rebalance 才生效。
   

   [root@kvm4 ~(keystone_admin)]# swift-ring-builder /etc/swift/container.builder remove 192.168.122/z1d1
   d0r1z1-192.168.122:6001/z1d1_"" marked for removal and will be removed next rebalance.
   [root@kvm4 ~(keystone_admin)]# swift-ring-builder /etc/swift/container.builder remove 192.168.122/z2d1
   d1r1z2-192.168.122:6001/z2d1_"" marked for removal and will be removed next rebalance.
   

3. 進行 container.builde 的 rebalance。
   

   [root@kvm4 ~(keystone_admin)]# swift-ring-builder /etc/swift/container.builder rebalance
   Reassigned 512 (100.00%) partitions. Balance is now 0.00.
   

4. 再次查看 container.builde，已剩下正確的兩項，且 partitions 也修正。
   

   [root@kvm4 ~(keystone_admin)]# swift-ring-builder /etc/swift/container.builder
   /etc/swift/container.builder, build version 7
   512 partitions, 2.000000 replicas, 1 regions, 2 zones, 2 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
                2     1     1   192.168.122.4  6001      z1d1 100.00        512   0.00 
                3     1     2   192.168.122.4  6001      z2d1 100.00        512   0.00
   

5. 使用以下方式直接刪除 account 的相關檔案，就可以重新再做。
   

   [root@kvm4 ~(keystone_admin)]# rm /etc/swift/account.builder
   [root@kvm4 ~(keystone_admin)]# rm /etc/swift/account.ring.gz
   [root@kvm4 ~(keystone_admin)]# rm /etc/swift/backups/*account.builder
   [root@kvm4 ~(keystone_admin)]# rm /etc/swift/backups/*account.ring.gz
