swift分布式存储添加存储节点
|
swift分布式存储添加节点需要新的节点信息加入到ring中记录下来 1、在ring中添加两个节点的信息 swift@server1:/etc/swift> export ZONE=4 swift@server1:/etc/swift> export STORAGE_LOCAL_NET_IP=192.168.1.215 swift@server1:/etc/swift> export WEIGHT=100 swift@server1:/etc/swift> export DEVICE=sdb1 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 $WEIGHT swift@server1:/etc/swift> export ZONE=5 swift@server1:/etc/swift> export STORAGE_LOCAL_NET_IP=192.168.1.216 swift@server1:/etc/swift> sudo swift-ring-builder account.builder add z$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 Devices: id region zone ip address port replication ip replication port name weight partitions balance meta 13 1 1 192.168.1.212 6002 192.168.1.212 6002 sdb1 100.00 262144 66.67 14 1 2 192.168.1.213 6002 192.168.1.213 6002 sdb1 100.00 262144 66.67 15 1 3 192.168.1.214 6002 192.168.1.214 6002 sdb1 100.00 262144 66.67 16 1 4 192.168.1.215 6002 192.168.1.215 6002 sdb1 100.00 0 -100.00 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,100.00 balance The minimum number of hours before a partition can be reassigned is 1 Devices: id region zone ip address port replication ip replication port name weight partitions balance meta 3 1 1 192.168.1.212 6001 192.168.1.212 6001 sdb1 100.00 262144 66.67 4 1 2 192.168.1.213 6001 192.168.1.213 6001 sdb1 100.00 262144 66.67 5 1 3 192.168.1.214 6001 192.168.1.214 6001 sdb1 100.00 262144 66.67 6 1 4 192.168.1.215 6001 192.168.1.215 6001 sdb1 100.00 0 -100.00 7 1 5 192.168.1.216 6001 192.168.1.216 6001 sdb1 100.00 0 -100.00 swift@server1:/etc/swift> sudo swift-ring-builder object.builder object.builder,100.00 balance The minimum number of hours before a partition can be reassigned is 1 Devices: id region zone ip address port replication ip replication port name weight partitions balance meta 3 1 1 192.168.1.212 6000 192.168.1.212 6000 sdb1 100.00 262144 66.67 4 1 2 192.168.1.213 6000 192.168.1.213 6000 sdb1 100.00 262144 66.67 5 1 3 192.168.1.214 6000 192.168.1.214 6000 sdb1 100.00 262144 66.67 6 1 4 192.168.1.215 6000 192.168.1.215 6000 sdb1 100.00 0 -100.00 7 1 5 192.168.1.216 6000 192.168.1.216 6000 sdb1 100.00 0 -100.00 2、平衡ring swift@server1:/etc/swift> sudo swift-ring-builder account.builder rebalance Reassigned 262144 (100.00%) partitions.
