when I installed Raspbian Stretch Lite (2018-11-13) on my 16GB SD card, with dd (dd bs=4M if=2018-11-13-raspbian-stretch-lite.img of=/dev/sdb conv=fsync) and then tried it, I quickly ran out of space so I checked it with df -hl and then with parted and this is what I got:

  • df

    /dev/root 1,7G 1,5G 105M 94% / devtmpfs 460M 0 460M 0% /dev tmpfs 464M 0 464M 0% /dev/shm tmpfs 464M 12M 452M 3% /run tmpfs 5,0M 4,0K 5,0M 1% /run/lock tmpfs 464M 0 464M 0% /sys/fs/cgroup /dev/mmcblk0p1 44M 23M 22M 51% /boot tmpfs 93M 0 93M 0% /run/user/1000 total 3,6G 1,5G 2,1G 43% -

  • parted

    1 4194kB 50,2MB 46,0MB primary fat32 LBA 2 50,3MB 15,9GB 15,9GB primary ext4

    where 1 is boot and 2 rootfs

Is it normal? How can I use whole SD card?

The listings you posted are inconsistent. It looks like the partition table was resized on initial boot, but the filesystem was not resized.

You could try sudo resize2fs /dev/mmcblk0p2 to adjust the partition.

If this is unsuccessful there is either something wrong with the image (did you check the checksum after downloading) or the card is faulty.

You COULD try rebooting to a root shell and can repair most such problems on the Pi.

1. Append `init=/bin/sh` at the end of `cmdline.txt` and reboot.
2. After booting you will be at the prompt in a root shell.
3. Your root file system is mounted as readonly now, so remount it as
read/write `mount -n -o remount,rw /`

Get another SDCard and a fresh copy of Raspbian Stretch Lite 2018-11-13 on it. Boot that in your RPi and sudo apt install raspberrypi-ui-mods (to give you a basic GUI) and sudo apt install parted gparted (Get gparted as the GUI version of parted is easier to use than the command line one.)

Get your 16GB SDCard in a USB reader, mount the USB reader in your RPi.

Use gparted to move and re-size the root partition to use all of the space.

Shutdown, swap cards, reboot, keep calm and carry on. Keep that spare SDCard as a rescue system for the next time you get in a mess.

You could do the same on your laptop with a gparted live CD/USB from Gparted Live CD booted instead of Windows.

Follow the instructions as in the link: https://thepi.io/how-to-install-raspbian-on-the-raspberry-pi/ Before that just format your sd cart properly so when you insert your cart again it will show you smth like 15,9 of 16,0 free.

  • That tutorial is ancient and I would not use or recommend it.

    Some of the problems: it refers to Jessie, the downloads have changed considerably. The common names given to the images ('Raspbian Jessie with Pixel') cannot be found on the downloads page. You don't need to unzip if you use Etcher. Etcetera, etcetera. The main effect will be that it confuses a first time Pi user. Not helpful at all.

I recommend doing a clean install, using this guide on the RaspPi website. Use Etcher, insert the microSD card into a reader which connects to USB, and it should reformat and flash your card.

Etcher doesn't require anything, it does it all for you. So you won't have to worry about the format or partitions.

For the adapter, you could get a microSD to SD adapter, and a SD card usb reader, insert the microSD into the adapter and the SD adapter into the usb reader, then run Etcher on that drive.

  • That doesn't really solve the OP's problem as they're trying to make a copy of their existing system to gain more space.
