swift扩容-创新互联
swift扩容有增加node节点的硬盘和增加node节点2种方式。
本文基于上篇 http://fire7758.blog.51cto.com/993821/1374190
一、Node中增加硬盘
如node2中增加硬盘扩容，这里以增加/dev/sdc为例。
1）Node2操作
#parted /dev/sdc mklabel gpt
#parted /dev/sdc mkpart primary 0% 100%
#mkfs.xfs -i size=1024 /dev/sdc1
#mkdir -p /srv/node/sdc1
#echo "/dev/sdc1 /srv/node/sdc1 xfsnoatime,nodiratime,nobarrier,logbufs=8 0 0" >> /etc/fstab
#mount /srv/node/sdc1
#chown -R swift:swift /srv/node/sdc1
2）ProxyNode操作
给Node2添加ring
swift-ring-builder account.builder add z2-192.168.1.228:6002/sdc1100
swift-ring-builder container.builder add z2-192.168.1.228:6001/sdc1100
swift-ring-builder object.builder add z2-192.168.1.228:6000/sdc1100
确认ring内容
swift-ring-builder /etc/swift/account.builder
swift-ring-builder /etc/swift/container.builder
swift-ring-builder /etc/swift/object.builder
Rebalancethe rings
swift-ring-builder account.builder rebalance
swift-ring-builder container.builder rebalance
swift-ring-builder object.builder rebalance
复制account.ring.gz, container.ring.gz, andobject.ring.gz到其他proxy Node及Storage Node
# scp *.ring.gz swift1:/etc/swift
# scp *.ring.gz swift2:/etc/swift
# scp *.ring.gz swift3:/etc/swift
所有node检查/etc/swift权限，owner修改为swift
#chown -R swift:swift /etc/swift/
二、添加新机器
如增加节点node4
在node4上做如下设置：（上篇的章节）
General Installation Steps for All Nodes
General Installation Steps for All Swift Nodes（includeproxy）
时间同步
修改hosts文件
Swift Storage Node安装步骤
在proxy Node上做如下设置
给node4添加ring
swift-ring-builder account.builder add z3-192.168.1.229:6002/loop100
swift-ring-builder container.builder add z3-192.168.1.229:6001/loop100
swift-ring-builder object.builder add z3-192.168.1.229:6000/loop100
确认ring内容
swift-ring-builder /etc/swift/account.builder
swift-ring-builder /etc/swift/container.builder
swift-ring-builder /etc/swift/object.builder
Rebalancethe rings
swift-ring-builder account.builder rebalance
swift-ring-builder container.builder rebalance
swift-ring-builder object.builder rebalance
复制account.ring.gz, container.ring.gz, andobject.ring.gz到其他proxy Node及Storage Node
# scp *.ring.gz swift1:/etc/swift
# scp *.ring.gz swift2:/etc/swift
# scp *.ring.gz swift3:/etc/swift
# scp *.ring.gz swift4:/etc/swift
所有node检查/etc/swift权限，owner修改为swift
#chown -R swift:swift /etc/swift/
重启动proxy Node
#swift-init proxy restart
启动Node4
#swift-init all start
