No space left on device even though I should have increased the storage size

Federico Corazza

I should have increased the storage size following the instructions in the docs and this is what I get with df -h

root@Omega-616B:~# df -h
Filesystem                Size      Used Available Use% Mounted on
/dev/root                 5.8M      5.8M         0 100% /rom
tmpfs                    61.4M     25.2M     36.1M  41% /tmp
/dev/mmcblk0p1            3.5G     63.2M      3.3G   2% /overlay
overlayfs:/overlay        3.5G     63.2M      3.3G   2% /
tmpfs                   512.0K         0    512.0K   0% /dev
/dev/sda1                14.9G      2.0G     13.0G  13% /mnt/sda1

I've increased the storage with a 4 GB SD and added a 2 GB swap inside a 16GB USB.

However when I run pip3 install pandas I get:

root@Omega-616B:~# pip3 install pandas

I'd like to use the sd card for every file needed by the system to run stuff like python and its libraries for example, and on the usb I'd like to keep my files like a home folder. For the latter I thought I'd make a homedirectory inside the usb drive and add a symlink to the root directory but I'm not sure it's the right way to accomplish what I want.

Can you try running with the pip3 command with -v for more verbosity? Maybe it's trying to uncompress it on in the /tmp folder and runs out of space?
