1、将剩余空间分出来
[root@localhost ~]# parted /dev/sda 慎重选择磁盘
GNU Parted 2.1
Using /dev/sda
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) mkpart
Partition name? []? data
File system type? [ext2]? ext4
Start? 226G
End? -1s
Warning: You requested a partition from 226GB to 598GB.
The closest location we can manage is 226GB to 598GB.
Is this still acceptable to you?
Yes/No? y
Warning: WARNING: the kernel failed to re-read the partition table on /dev/sda (Device or resource busy). As a
result, it may not reflect all of your changes until after reboot.

2、格式化新分区
[root@localhost ~]# mkfs.ext4 /dev/sda5

3、挂载分区
[root@localhost /]# mkdir /data
[root@localhost /]#
[root@localhost /]# mount /dev/sda5 /data
[root@localhost /]# df -Th
Filesystem Type Size Used Avail Use% Mounted on
/dev/sda3 ext4 197G 3.0G 184G 2% /
tmpfs tmpfs 32G 72K 32G 1% /dev/shm
/dev/sda2 ext4 194M 34M 151M 19% /boot
/dev/sda1 vfat 200M 260K 200M 1% /boot/efi
/dev/sda5 ext4 342G 195M 324G 1% /data
4、设置开机启动
