suse和linux其他发行版本分区和LVM没有区别，主要是两个步骤：
一是分区，主要步骤是分区—刷新分区表—格式化，具体用什么方式分区、用什么方式刷新分区表、格式化成什么格式，方法有很多，根据实际情况而定，但总体思路不变；
二是创建物理卷、卷组和逻辑卷，主要步骤是依次创建物理卷、卷组、逻辑卷—格式化—挂载—配置/etc/fstab开机自动挂载；

The partition table has been altered!
Calling ioctl() to re-read partition table.
WARNING: Re-reading the partition table failed with error 16: 设备或资源忙.
The kernel still uses the old table. The new table will be used at
the next reboot or after you run partprobe(8) or kpartx(8)

#fdisk分区完成之后，警告说内核仍然使用旧的分区表，需要重启系统或者执行partprobe、kpartx这两个其中一个命令；
#使用fdisk对/dev/sda分出第三个区，跟着提示操作，是在不知道的话输入m看提示；
