1、在控制台上将需要扩充的硬盘增加空间
将硬盘大小由原来的50G升级到200G
2、登录所挂载的服务器
1）查看硬盘分区情况
admin@ip-172-31-121-13:~$ sudo lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
nvme0n1 259:0 0 200G 0 disk
├─nvme0n1p1 259:1 0 49.9G 0 part /
├─nvme0n1p14 259:2 0 3M 0 part
└─nvme0n1p15 259:3 0 124M 0 part /boot/efi
2）将硬盘扩充
admin@ip-172-31-121-13:~$ sudo growpart /dev/nvme0n1 1
CHANGED: partition=1 start=262144 old: size=104595423 end=104857566 new: size=419168223 end=419430366
3）刷新硬盘大小
admin@ip-172-31-121-13:~$ sudo resize2fs /dev/nvme0n1p1
resize2fs 1.47.0 (5-Feb-2023)
[7753389.789944] EXT4-fs (nvme0n1p1): resizing filesystem from 13074427 to 52396027 blocks
Filesystem at /dev/nvme0n1p1 is mounted on /; on-line resizing required
old_desc_blocks = 7, new_desc_blocks = 25
[7753391.375495] EXT4-fs (nvme0n1p1): resized filesystem to 52396027
The filesystem on /dev/nvme0n1p1 is now 52396027 (4k) blocks long.
4）验证是否扩充成功
admin@ip-172-31-121-13:~$ sudo df -h
Filesystem Size Used Avail Use% Mounted on
udev 7.7G 0 7.7G 0% /dev
tmpfs 1.6G 704K 1.6G 1% /run
/dev/nvme0n1p1 197G 47G 142G 25% /
tmpfs 7.7G 0 7.7G 0% /dev/shm
tmpfs 5.0M 0 5.0M 0% /run/lock
/dev/nvme0n1p15 124M 12M 113M 10% /boot/efi
tmpfs 1.6G 0 1.6G 0% /run/user/0
tmpfs 1.6G 0 1.6G 0% /run/user/1000
如果我们是整块硬盘在使用而没有进行分区的话，我们只需要执行resize2fs /dev/nvme0n1p1即可
