How to set up Software raid1 configuration on a running system
This guide explains how to set up software RAID1 on an already running RHEL 4 system. The GRUB bootloader will be configured in such a way that the system will still be able to boot if one of the hard drives fails (no matter which one).[@more@]Introduce my environment:In my test environment I'm using a RHEL 4 U 5 system with two hard drives, /dev/sda and /dev/sdb which are identical in size. /dev/sdb is currently unused, and /dev/sda has the following partitions:/dev/sda1: /boot partition, ex
linux下软raid的实现
raid是当前存储提高安全和性能的主要技术手段,实现raid一般用raid卡实现,也就是硬raid。除此之外,我们还可以用软件来实现raid技术。这篇文章就简单介绍如何用软件实现raid技术(以raid0为例)。参考:http://space6212.itpub.net/post/12157/306986但觉的步骤有点问题,且在生成mdadm配置文件写的不够详细,现整理一下以备后查.[@more@]有两个可以实现软raid的工具:raidtools, mdadm。raidtool,这是在RHEL3中所使用的,但是我在RHEL4中没有找到raidtool,只有mdadm,看来RH也是偏向于使用mdadm的。本文也以mdadm为例讲述。一、查看当前硬
