So I had to reinstall Debian in the sdcard of my Orange Pi Lite. Thing is original image / fs is only 4Gb, which on a 64Gb sdcard leaves 60Gb unused.
Here is where parted comes to the rescue. Easier than fdisk for me. Below example extends ext4 partition to 62Gb and creates a 2Gb swap partition.
sudo parted /dev/mmcblk0 GNU Parted 3.2 Using /dev/mmcblk0 Welcome to GNU Parted! Type 'help' to view a list of commands. (parted) print Model: SD BC2QT (sd/mmc) Disk /dev/mmcblk0: 64,0GB Sector size (logical/physical): 512B/512B Partition Table: msdos Disk Flags: Number Start End Size Type File system Flags 1 21,0MB 73,4MB 52,4MB primary fat16 lba 2 73,4MB 3743MB 3670MB primary ext4 (parted) resizepart Partition number? 2 End?

Now we only need to execute e2fsck and resize2fs on the extended partition.
sudo e2fsck -f /dev/mmcblk0p2 e2fsck 1.44.5 (15-Dec-2018) rootfs: recovering journal Pass 1: Checking inodes, blocks, and sizes Pass 2: Checking directory structure Pass 3: Checking directory connectivity Pass 4: Checking reference counts Pass 5: Checking group summary information rootfs: 109610/225344 files (0.2% non-contiguous), 650426/896000 blocks user@computer: ~ $ sudo resize2fs /dev/mmcblk0p2 resize2fs 1.44.5 (15-Dec-2018) Resizing the filesystem on /dev/mmcblk0p2 to 15118798 (4k) blocks. The filesystem on /dev/mmcblk0p2 is now 15118798 (4k) blocks long.
Afterwards we can insert the sdcard into the OrangePi to have a 60Gb root partition.
sudo fdisk -l Disk /dev/mmcblk0: 59.6 GiB, 64021856256 bytes, 125042688 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: 0x00037d04 Device Boot Start End Sectors Size Id Type /dev/mmcblk0p1 40960 143359 102400 50M c W95 FAT32 (LBA) /dev/mmcblk0p2 143360 121093750 120950391 57.7G 83 Linux /dev/mmcblk0p3 121094144 125042687 3948544 1.9G 82 Linux swap / Solaris
After OS boots we need to mkswap, activate and modify /etc/fstab.
