现象: 执行slaveof同步该数据时一直报timeout,无法完成数据同步。 原因: pika master节点配置了千兆网卡,出现了网卡降速,降低到100Mb/s. 定位过程: 执行netstat -na|grep {port}发现回包积压严重,查看监控发现内存一直上涨,查看网卡带宽发现降低到100Mb/s,怀疑rsync请求的数据包大于网卡带宽导致请求无法及时收到回包,rsync client应用层重传导致进一步加剧。当前pika节点所在物理机除pika外还部署了一个proxy节点。 运维操作:
复现方法: master端:写入一批数据到RocksDB中,通过wondershaper限制master端网络带宽。(sudo wondershaper -a {device} -u 102400),取消限速执行sudo wondershaper -a {device} -c slave端:执行slaveof force命令从master同步数据。

现象:
执行slaveof同步该数据时一直报timeout,无法完成数据同步。
原因:
pika master节点配置了千兆网卡,出现了网卡降速,降低到100Mb/s.
定位过程:
执行netstat -na|grep {port}发现回包积压严重,查看监控发现内存一直上涨,查看网卡带宽发现降低到100Mb/s,怀疑rsync请求的数据包大于网卡带宽导致请求无法及时收到回包,rsync client应用层重传导致进一步加剧。当前pika节点所在物理机除pika外还部署了一个proxy节点。

复现方法:
master端:写入一批数据到RocksDB中,通过wondershaper限制master端网络带宽。(sudo wondershaper -a {device} -u 102400),取消限速执行sudo wondershaper -a {device} -c
slave端:执行slaveof force命令从master同步数据。
