#NFS文件系统是基于网络层面,需要通过网络实现数据的同步 #NFS服务端给NFS客户端提供服务需要借助RPC协议的rpcbind服务(CentOS6开始的叫法,CentOS5及之前叫portmap服务),实现通信 #NFS不监听任何端口;最终实现TCP/IP通信的过程是由RPC监听111端口实现的 NFS传输过程:先由服务端的NFS服务在RPC服务商注册一个端口,然后服...

由于目前线上的两台NFS服务器,一台为主,一台为备。主到备的数据同步,靠rsync来做。由于数据偏重于图片业务,并且还是千万级的碎图片。在目前的业务框架下,NFS服务是存在单点的,并且数据的同步也不能做完全实时性,从而导致不能确保一致性。因此,出于对业务在线
Now, any host that has a network route to the kubernetes nodes on which these daemons are running will be able to get to the nfs servers via ports 30806 and 32376. Note that when you run this command, you'll likely get a different pair of ports. It is possible to request a certain...
