rPi install keeps saying no space left on device

Installation
1

It’s probably just me, but Home-Assistant just won’t install on RaspberryPi with EmonSD image as base.
It kept throwing errors after Cleaning up… ending in OSError: [Errno 28] No space left on device.
Here’s example of when I try to force reinstall:

OSError: [Errno 28] No space left on device

Storing debug log for failure in /root/.pip/pip.log

I ended up installing the various pip module individually, last one missing afaict was sqlalchemy
When I try to install that I get similar OSError: [Errno 28] No space left on device error:

I’m confused as there seems to be plenty of space available:

998×572 71.6 KB

I was going to following instructions to integrate Emon with Home-Assistant but can’t get to past install https://github.com/openenergymonitor/oem_home-assistant

Many thanks!

My wild guess is your /tmp is running out of space. If you unmount /tmp you will use your sd card and that might have sufficient space available

Thanks that fixed it!

I’m trying to install Home Assistant into an Onion Omega2+. I’m having the same error message when I run hass for the first time and it tries to install SQLAlchemy 1.1.5. This renders the entire recorder module offline.

I tried to install this dependencies (SQLAlchemy, record, ExtensionClass) manually using pip3 and all ends up throwing this error on ExtensionClass:

root@Omega-B195:~# pip3 install ExtensionClass
Collecting ExtensionClass
  Using cached ExtensionClass-4.2.1.tar.gz
Installing collected packages: ExtensionClass
  Running setup.py install for ExtensionClass ... error

I have plenty of disk space:

tmpfs                   512.0K         0    512.0K   0% /dev

When I try to unmount /tmp, I get a resource busy error (even with -f).

I tried to install it using easy-install and I have the same problem.

I’ll post this in the Onion forums too. In the mean time, any suggestions?
Thanks in advance.

Use -l to unmount, “sudo umount -l /tmp”

You can try doing a remount to increase the partition’s size.

sudo mount -o remount,size=100M /tmp

Other option is to comment out temporarily the respective line in /etc/fstab, reboot, install and then uncomment and reboot again to restore tmp to be in-memory file system.

Another, simpler option is to set TMPDIR to a directory with plenty of space, such as export TMPDIR=/home/homeassistant/tmp (make sure you created it) before running the install command.
