在CentOS 6.4上源码安装SWIFT从百兆换到千兆的错误

hosyp

在CentOS 6.4上源码安装SWIFT，设定4台storageNode, Sun Fire X4500，46块500M硬盘，为节约硬件，swift-proxy server装在controllerNode上，采用keystone认证。
1.百兆网，controllerNode（em1):192.168.0.151, storageNode(em1):192.168.0.193-196
   源码安装，设置Glance使用Swift，上载Image正常，>5G文件默认200Msplit上保存正常，改为1Gsplit保存正常
2.千兆网，controllerNode（em2):172.16.0.151, storageNode(em2):172.16.0.193-196
   上载Image正常，>5G文件默认200Msplit上保存正常，改为1Gsplit保存出错

3.关掉em2，将em1全换到千兆网，还是出错，连<2G文件都上传出错
   难道SWIFT不能用千兆网？当然能用，最后，发现总是timeout错误在ProxyServer上！
   将node_timeout 从10增加到100，client_timeout从60增加到600 in proxy-server.conf，一切正常了！
