swift分佈式存儲添加節點須要新的節點信息加入到ring中記錄下來node

一、在ring中添加兩個節點的信息
swift

swift@server1:/etc/swift> export ZONE=4app

swift@server1:/etc/swift> export STORAGE_LOCAL_NET_IP=192.168.1.215async

swift@server1:/etc/swift> export WEIGHT=100分佈式

swift@server1:/etc/swift> export DEVICE=sdb1ide

swift@server1:/etc/swift> sudo swift-ring-builder account.builder add z$ZONE-$STORAGE_LOCAL_NET_IP:6002/$DEVICE $WEIGHTui

swift@server1:/etc/swift> sudo swift-ring-builder container.builder add z$ZONE-$STORAGE_LOCAL_NET_IP:6001/$DEVICE $WEIGHTthis

swift@server1:/etc/swift> sudo swift-ring-builder object.builder add z$ZONE-$STORAGE_LOCAL_NET_IP:6000/$DEVICE $WEIGHTrest

swift@server1:/etc/swift> export ZONE=5server

swift@server1:/etc/swift> export STORAGE_LOCAL_NET_IP=192.168.1.216

swift@server1:/etc/swift> sudo swift-ring-builder account.builder add z$ZONE-$STORAGE_LOCAL_NET_IP:6002/$DEVICE $WEIGHT

swift@server1:/etc/swift> sudo swift-ring-builder container.builder add z$ZONE-$STORAGE_LOCAL_NET_IP:6001/$DEVICE $WEIGHT

swift@server1:/etc/swift> sudo swift-ring-builder object.builder add z$ZONE-$STORAGE_LOCAL_NET_IP:6000/$DEVICE $WEIGHT

查看ring的信息

swift@server1:/etc/swift> sudo swift-ring-builder account.builder

account.builder, build version 38

262144 partitions, 3.000000 replicas, 1 regions, 5 zones, 5 devices, 100.00 balance

The minimum number of hours before a partition can be reassigned is 1

17 1 5 192.168.1.216 6002 192.168.1.216 6002 sdb1 100.00 0 -100.00

swift@server1:/etc/swift> sudo swift-ring-builder container.builder

container.builder, build version 13

262144 partitions, 3.000000 replicas, 1 regions, 5 zones, 5 devices, 100.00 balance

The minimum number of hours before a partition can be reassigned is 1

swift@server1:/etc/swift> sudo swift-ring-builder object.builder

object.builder, build version 13

262144 partitions, 3.000000 replicas, 1 regions, 5 zones, 5 devices, 100.00 balance

The minimum number of hours before a partition can be reassigned is 1

7 1 5 192.168.1.216 6000 192.168.1.216 6000 sdb1 100.00 0 -100.00

二、平衡ring

swift@server1:/etc/swift> sudo swift-ring-builder account.builder rebalance

Reassigned 262144 (100.00%) partitions. Balance is now 16.67.

-------------------------------------------------------------------------------

NOTE: Balance of 16.67 indicates you should push this

ring, wait at least 1 hours, and rebalance/repush.

-------------------------------------------------------------------------------

swift@server1:/etc/swift> sudo swift-ring-builder container.builder rebalance

Reassigned 262144 (100.00%) partitions. Balance is now 16.67.

-------------------------------------------------------------------------------

NOTE: Balance of 16.67 indicates you should push this

ring, wait at least 1 hours, and rebalance/repush.

-------------------------------------------------------------------------------

swift@server1:/etc/swift> sudo swift-ring-builder object.builder rebalance

Reassigned 262144 (100.00%) partitions. Balance is now 16.67.

-------------------------------------------------------------------------------

NOTE: Balance of 16.67 indicates you should push this

ring, wait at least 1 hours, and rebalance/repush.

-------------------------------------------------------------------------------

swift@server1:/etc/swift> sudo chown swift:swift *

拷貝ring文件到全部的存儲節點

三、配置添加的存儲節點

參考以前的文章配置配置215和216，注意目錄和文件的權限

啓動215和216的服務

以後記得其餘節點重啓服務

proxy節點

swift@server1:/etc/swift> sudo swift-init proxy restart

Signal proxy-server pid: 23568 signal: 15

proxy-server (23568) appears to have stopped

Starting proxy-server...(/etc/swift/proxy-server.conf)

storage節點

# swift-init all restart

注意

server5:/ # chown -R swift:swift /srv/node/sdb1

server6:/ # chown -R swift:swift /srv/node/sdb1

剛開始前三臺存儲節點上的數據

swift@server2:/srv/node/sdb1> du -sh *

16K accounts

356M async_pending

129M containers

5.0G objects

0 tmp

添加後兩臺存儲節點以後的數據分佈

wift@server2:/srv/node/sdb1> du -sh *

16K accounts

197M async_pending

129M containers

2.5G objects

0 tmp

swift@server3:/srv/node/sdb1> du -sh *

16K accounts

175M async_pending

129M containers

2.5G objects

0 tmp

swift@server4:/srv/node/sdb1> du -sh *

0 accounts

244M async_pending

129M containers

3.0G objects

0 tmp

server5:/srv/node/sdb1 # du -sh *

68M containers

2.7G objects

0 tmp

server6:/srv/node/sdb1 # du -sh *

16K accounts

32K containers

2.8G objects

0 tmp
