CentOS磁盘分区添加删除

Linux硬盘分区（一）：添加
********************************

*************************
过程简述

*************************

1. --添加磁盘@H_404_9@
2. #fdisk-l--查看磁盘情况@H_404_9@
3. #fdisk/dev/sdb--为/dev/sdb设备分区@H_404_9@
4. n--添加分区@H_404_9@
5. p/e--主分区/逻辑分区@H_404_9@
6. w--保存退出@H_404_9@
7. #mkdir/data--创建挂载目录@H_404_9@
8. #mkfs.ext3/dev/sdb--格式化磁盘为ext3文件系统@H_404_9@
9. #fdisk-l--再次查看磁盘情况@H_404_9@
10. #mount/dev/sdb/data--挂载磁盘到创建的挂载目录下@H_404_9@
11. #vi/etc/fstab--修改启动自动挂载项@H_404_9@
12. /dev/sdb/dataext3defaults00@H_404_9@

1、以上操作为精炼总结，若如可以看懂，下面内容无需浏览；
2、以下简单列举两例，细化操作过程。

*****************************************************************************************************

举例1：添加1块90G磁盘，将其分为1个分区

*****************************************************************************************************

举例2：

1、添加1块10G磁盘；
2、将其分为六个分区；
3、三个主分区分别为2G；
4、剩余空间分为扩展分区，具体分为两个逻辑分区分别为1G，剩余空间单独分为一个逻辑分区。
