linux 磁盘分区挂载-fdisk

Shun

题外话：今天不废话，直接上操作，linux磁盘分区，所有的操作标记颜色

Welcome to fdisk (util-linux 2.23.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
Device does not contain a recognized partition table
Building a new DOS disklabel with disk identifier 0xcda7f5f7.
Command (m for help): n
Partition type:回车
p   primary (0 primary, 0 extended, 4 free)
e   extended
Select (default p): p
Partition number (1-4, default 1): 默认是1.可以输入1 或者直接回车
First sector (2048-1048575999, default 2048): 磁盘开始位置，可以输入，可以直接回车
Using default value 2048
Last sector, +sectors or +size{K,M,G} (2048-1048575999, default 1048575999): 可以输入500G 或者回车
Using default value 1048575999
Partition 1 of type Linux and of size 500 GiB is set
Command (m for help): t
Selected partition 1

第二步：进行格式化
[root@zjy-dbana /]# mkfs.ext4 /dev/vdd1
mke2fs 1.42.9 (28-Dec-2013)
Filesystem label=
OS type: Linux

[root@zjy-dbana /]#
格式化方式二：mkfs.xfs -f /dev/vdb1
[root@VM-0-31-centos ~]# mkfs.xfs -f /dev/vdb1
meta-data=/dev/vdb1              isize=512    agcount=4, agsize=32767936 blks

data     =                       bsize=4096   blocks=131071744, imaxpct=25
=                       sunit=0      swidth=0 blks
naming   =version 2              bsize=4096   ascii-ci=0 ftype=1
log      =internal log           bsize=4096   blocks=63999, version=2

[root@VM-0-31-centos ~]#
第三步：挂载
准备挂载文件夹 backup
创建文件夹
[root@zjy-dbana /]# mkdir -p /backup/
文件挂载
[root@zjy-dbana /]# mount /dev/vdd1 /backup
永久生效
[root@zjy-dbana /]# cat /etc/mtab  -- 查看到最后一条复制下来

第四步：验证
[root@zjy-dbana /]# df -h
