1.问题描述

树苺派4B，配置32GB的SD卡。系统安装完毕，拷贝程序时，因为空间有限而中断。通过输入df或df -h命令查询树莓派SD 卡空间使用情况

pi@raspberrypi:/ $ df -h Filesystem Size Used Avail Use% Mounted on /dev/root 6.8G 6.5G 51M 100% / devtmpfs 1.9G 0 1.9G 0% /dev tmpfs 2.0G 0 2.0G 0% /dev/shm tmpfs 2.0G 8.6M 1.9G 1% /run tmpfs 5.0M 4.0K 5.0M 1% /run/lock tmpfs 2.0G 0 2.0G 0% /sys/fs/cgroup /dev/mmcblk0p1 253M 40M 213M 16% /boot tmpfs 391M 0 391M 0% /run/user/1000

由上可见，系统未能完全识别SD卡空间。

2.解决方法

输入如下命令

pi@raspberrypi:/ $ sudo raspi-config

在弹出的Raspberry Pi Software Configuration Tool(raspi-config)配置界面中，依次选择（1）7 Advanced Options: Configure advanced settings （2）Expand Filesystem: Ensures that all of the SD card storage is available to the os 回车，搞定。将在terminal中显示如下内容信息

pi@raspberrypi:/ $ sudo raspi-config Welcome to fdisk (util-linux 2.33.1). Changes will remain in memory only, until you decide to write them. Be careful before using the write command. Command (m for help): Disk /dev/mmcblk0: 29.7 GiB, 31914983424 bytes, 62333952 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x9fd26ab3 Device Boot Start End Sectors Size Id Type /dev/mmcblk0p1 8192 532480 524289 256M c W95 FAT32 (LBA) /dev/mmcblk0p2 540672 15138815 14598144 7G 83 Linux Command (m for help): Partition number (1,2, default 2): Partition 2 has been deleted.

重启之后，即可正常显示全部空间。扩容完毕。

pi@raspberrypi:~ $ df -h Filesystem Size Used Avail Use% Mounted on /dev/root 29G 6.5G 22G 24% / devtmpfs 1.9G 0 1.9G 0% /dev tmpfs 2.0G 0 2.0G 0% /dev/shm tmpfs 2.0G 17M 1.9G 1% /run tmpfs 5.0M 4.0K 5.0M 1% /run/lock tmpfs 2.0G 0 2.0G 0% /sys/fs/cgroup /dev/mmcblk0p1 253M 40M 213M 16% /boot tmpfs 391M 0 391M 0% /run/user/1000
