前言

已经实施过2次Hadoop大数据平台的基础环境搭建,对于硬盘的RAID模式都不约而同选择了JBOD,毕竟大数据对于文件系统的管理本身就是基于分布式,由至少3份副本来保障数据可靠性,只是不做RAID后的SAS硬盘读写性能就有点惨不忍睹。这次Hadoop大数据平台工具选择的是Cloudera,大家感兴趣的化也可以浏览下它的官网。本篇文章主要介绍如何实现在不停机状态下在线更换JBOD硬盘。

JBOD原理

JBOD ( Just a Bunch Of Disks )不是标准的 RAID 等级,它通常用来表示一个没有控制软件提供协调控制的磁盘集合。 JBOD 将多个物理磁盘串联起来,提供一个巨大的逻辑磁盘。 JBOD 的数据存放机制是由第一块磁盘开始按顺序往后存储,当前磁盘存储空间用完后,再依次往后面的磁盘存储数据。 JBOD 存储性能完全等同于单块磁盘,而且也不提供数据安全保护。它只是简单提供一种扩展存储空间的机制, JBOD 可用存储容量等于所有成员磁盘的存储空间之和。目前 JBOD 常指磁盘柜,而不论其是否提供 RAID 功能。
