二、MooseFS的详解 1、MooseFS的优点 1）部署简单，轻量、易配置、易维护 2）易于扩展，支持在线扩容，不影响业务，体系架构可伸缩性极强 3）通用文件系统，不需要修改上层应用就可以使用（比那些需要专门api的dfs方便多了）。 4）以文件系统方式展示:如存图片，虽然存储在chunkserver上的数据是二进制文件，但是在挂载mfs的client端仍旧以图片文件形式展示，便于数据备份 5）硬盘利用率高。测试需要较大磁盘空间 6）可设置删除的空间回收时间，避免误删除文件丢失就恢复不及时影响业务 7）系统负载，即数据读写分配到所有的服务器上 8）可设置文件备份的副本数量，一般建议3份，未来硬盘容量也要是存储单份的容量的三倍 2、MooseFS的缺点 1）master目前是单点（虽然会把数据信息同步到备份服务器，但是恢复需要时间，因此，会影响上线，针对这个问题， 可以通过DRBD+Corosync+Pacemaker方案解决） 2）元数据服务器对主机的内存要求略高，所以元数据服务器硬件配置要高，尤其是内存 3、MooseFS文件系统结构 1）管理服务器 Master Server（Master） 2）元数据日志服务器 Metalogger Server(Metalogger) 3）数据存储服务器 Data Servers (Chunkservers) 4）客户端 Client 4、MooseFS各角色说明 1）Master管理服务器 有时也称为元数据服务器，负责管理各个数据存储服务器，调度文件读写，回收文件空间以及恢复多节点拷贝。目前MFS只支持一个元数据服务器master，这是一个单点故障，需要一个性能稳定的服务器来充当。希望今后MFS能支持多个master服务器，进一步提高系统的可靠性。 …
