I am very newbie in OrangePI PC. I have installed it by dd on my macOS, and I have tried installing a Raspbian image which downloaded from the orangepi.org in Windows as well, after installation when I check free disk space it is showing:
root@orangepi:~# df -h
Filesystem Size Used Avail Use% Mounted on
rootfs 3.4G 2.7G 474M 86% /
/dev/root 3.4G 2.7G 474M 86% /
devtmpfs 374M 0 374M 0% /dev
tmpfs 101M 188K 101M 1% /run
tmpfs 5.0M 0 5.0M 0% /run/lock
tmpfs 201M 0 201M 0% /run/shm
/dev/mmcblk0p1 41M 4.9M 37M 12% /boot
I have installed it on 32G flash drive. But when I check it through fdisk command it shows 32G as a disk size:
root@orangepi:~# sudo fdisk -l
Disk /dev/mmcblk0: 32.0 GB, 32010928128 bytes
4 heads, 16 sectors/track, 976896 cylinders, total 62521344 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
Disk identifier: 0x34605ba5

/dev/mmcblk0p1 40960 124927 41984 83 Linux
/dev/mmcblk0p2 124928 7170047 3522560 83 Linux
root@orangepi:~#
How to fix this?
This solved my problem (solution is taken from here):
root@orangepi:~# fdisk /dev/mmcblk0
Command (m for help): p
Disk /dev/mmcblk0: 15.8 GB, 15804137472 bytes

Command (m for help): d
Partition number (1-4): 2
Command (m for help): n
Partition type:
p primary (1 primary, 0 extended, 3 free)
e extended
Select (default p): p
Partition number (1-4, default 2): 2
First sector (2048-30867455, default 2048): 124928
Last sector, +sectors or +size{K,M,G} (124928-30867455, default 30867455):
Using default value 30867455
Command (m for help): w
Then quit (command q), reboot. You will then be able to use resize:
resize2fs /dev/root
