这段时间闲下来了，就把以前的知识巩固下也为了方便记忆。

下面是软raid5+lvm步骤软raid0,1,步骤类似了解raid概念请看上章节。 http://blog.youkuaiyun.com/make_zhf/article/details/73468647

1，将 /dev/sdj1 /dev/sdg1 /dev/sdi1 /dev/sdk1 四块盘做软raid5设备名为/dev/md5 热备一块盘实用也就三块盘。

2，将设备/dev/md5 做pv,vg,lv，mkfs.ext4 /dev/md5, mount.

（1）添加了/dev/sdj1 /dev/sdg1 /dev/sdi1 /dev/sdk1 四块盘
