Ubuntu22.04挂载扩容Cool-PI-4B(eMMC 32GB)
Ubuntu22.04 默认更新系统后,只有8GB空间,以下进行扩容,使用100%空间
- 更新前的容量如下:
ubuntu@coolpi:~$ df -h
Filesystem Size Used Avail Use% Mounted on
tmpfs 372M 4.0M 368M 2% /run
/dev/mmcblk0p2 6.4G 5.4G 704M 89% /
tmpfs 1.9G 0 1.9G 0% /dev/shm
tmpfs 5.0M 4.0K 5.0M 1% /run/lock
tmpfs 372M 124K 372M 1% /run/user/1000
ubuntu@coolpi:~$ sudo fdisk -l

- 采用parted命令进行扩容
ubuntu@coolpi:~$ sudo parted /dev/mmcblk0
GNU Parted 3.4
Using /dev/mmcblk0
Welcome to GNU Parted! Type 'help' to view a list of commands.
- 输入resizepart进行重新分配空间,并退出
(parted) resizepart
Partition number? 2
Warning: Partition /dev/mmcblk0p2 is being used. Are you sure you want to continue?
Yes/No? YES
End? [7340MB]? 100%
(parted) quit
- 重启系统
ubuntu@coolpi:~$ sudo reboot
- 查看更新后的容量
ubuntu@coolpi:~$ df -h
