一、关于硬盘
硬盘最小储存单位是：扇区
文件系统最小储存单位是：block （1kb or 4kb)
操作系统读取硬盘时，不会一个个扇区地去读取，这样效率太低，而是一次性读取多个扇区，即一次性读取一个“块”（block）。这种由多个扇区组成的“块”，是文件存取的最小单位，block的大小。最常见是1kb ，即连2个扇区组成一个block。（4K=8扇区）
硬盘类型：
SAS、SATA、SSD、SCSI、IDE
MBR与GPT分区表：
a) MBR,主引导记录（Master Boot Record）现有硬盘分区模式，MBR分区的标准决定了MBR只支持在2TB以内的硬盘，超过2TB的硬盘也只能管理2TB
磁盘的0柱面、0磁头、1扇区称为主引导扇区（也叫主引导记录MBR），它由三个部分组成，主引导程序、硬盘分区表DPT（Disk Partition table）和分区有效标志（55AA).
在总共512字节的主引导扇区里主引导程序（boot loader）占446个字节，第二部分是partition table区（分区表），即DPT，占64个字节，硬盘中分区有多少以及没一分区的大小都记在其中。第三部分magic number ，占2个字节，固定为55AA
b) GPT,全局唯一标识分区表（GUID Partition Table）,GUID全局唯一标识符（Globally Unique Identifier）。与MBR最大4个分区 表项的限制相比，GPT对分区数量没有限制。GPT可管理硬盘大小达到18EB（1EB=1024PB=1048576TB）
二、fdisk分区工具
先查看磁盘，sdb、sdc、sdd、sde、sdf、五个磁盘还没有分区
使用fdisk工具分区：一块磁盘可以分成4个主分区（4P）或者3个主分区加一个扩展分区（3p+1e）
[root@ip-lab_client ~]# lsblk

现在开始分区（4p）：

现在为止磁盘sdb已经分好了四个主分区，接下来要把分区全部格式化后，挂载到相应目录，
让磁盘开机自动挂载。挂载好磁盘才可以进行读写操作
将sdb1，sdb2，sdb3，sdb4格式化成ext3文件系统
[root@ip-lab_client ~]# mkfs -t ext3 -c /dev/sdb1
[root@ip-lab_client ~]# mkfs -t ext3 -c /dev/sdb2
[root@ip-lab_client ~]# mkfs -t ext3 -c /dev/sdb3
[root@ip-lab_client ~]# mkfs -t ext3 -c /dev/sdb4
然后将sdb1挂载在/home目录下，sdb2,sdb3,sdb4,分别挂载到/home/disk0, /home/disk1
, /home/disk2下
[root@ip-lab_client ~]# mkdir bak
[root@ip-lab_client ~]# cd bak
[root@ip-lab_client home]# mkdir disk0
[root@ip-lab_client home]# mkdir disk1
[root@ip-lab_client home]# mkdir disk2
编辑配置文件 /etc/fstab

分区完成就可以对磁盘进行读写操作了~。
在对sdc磁盘进行分区这一次（3p+1e）,然后采用UUid方式挂载。
