Centos7.x请参考：https://www.cnblogs.com/himismad/p/7851548.html
在内网主机Centos 6.5新增一个50G硬盘 （搭建在CAS服务器，直接新增存储）
新增一块磁盘主要需要做的有三步：格式化磁盘----分区----格式化分区----挂载

对磁盘/dev/vdb进行分区
[root@LX ~]# fdisk /dev/vdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0x60e70d89.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
switch off the mode (command 'c') and change display units to
sectors (command 'u').
