Low Disk Space on Filesystem root

[biketool]

Hello everybody,

I am trying to make a fresh install on my Pinephone, but it results in a device that is not booting anymore. I am flashing mobian-installer-pinephone-phosh-20220621.img to eMMC and the installation works as usual. After the installation I run apt update and apt upgrade and get this message in the status bar:

Low Disk Space on "Filesystem root"
The volume "Filesystem root" has only
166.3 MB disk space remaining.

The update process shows a littlebit later: No more disk space available.

Code:

I never had this disk space problem before, when I made a fresh installation. How should I make the installation and update to get a working system?

Emmc/SD card not being expanded on the Pinephone

On specific Pinephone installer images the storage medium Mobian is installed to does not get expanded to the full disk size. This can cause storage issues but can be fixed on the Pinephone in the terminal.

Assuming a ext4 setup.

First install parted by running

sudo apt install parted

Next, use parted on the correct drive

sudo parted /dev/mmcblkX

put 2 if its on a emmc. 0 for sd card verify with lsblk

To further verify run

print

Resize the second partition

resizepart 2 100%

Verify it has changed with

print

If you have FDE(Full Disk Encryption) setup run this to resize the encrypted device. If not using disk encryption skip this command.

sudo cryptsetup resize calamares_crypt

Next, resize the ext4 filesystem.

sudo resize2fs /dev/mapper/calamares_crypt

check the result with

df -h

This should fix the issue with file expansion on a fresh install.

If you have problems with parted I saved this from the faq and had to use the updated resize --> resizepart commands https://www.gnu.org/software/parted/manual/parted.html
