Error: ENOSPC: no space left on device

help
1

When I run Meteor in test mode, I get an error like the following:

Error: ENOSPC: no space left on device, write

OS: Ubuntu 16.04 LTS

Steps to reproduce:

  1. Create a new barebones Meteor project: meteor create meteorMocha then cd meteorMocha

  2. Run one of the following commands:

    meteor test --once --driver-package meteortesting:mocha

TEST_WATCH=1 meteor test --driver-package meteortesting:mocha

npm run test

In each case, I get output similar to the following, with a no space left on device error:

[[[[[ Tests ]]]]]

Evoking the Properties window on /tmp shows that I have 261,6 MB free space there. Here is the output of sudo df:

What can I do to solve or work around this error?

261,6 MB is just not enough. I’ve just checked, my own current Meteor install size is 310 MB.

Thanks @peterfkruger. I guessed as much. But I have over 16 GB free disk space. How can I either (a) tell tmp/ to use more of the free space, or (b) tell Meteor to build in a different directory?

It seems that you have plenty of space left on your file system /dev/nvme0n1p7 – this is where the /home directory is mounted on your system. So if you manage to tell meteor to forget /tmp and use the space that’s in your home directory, the problem will be solved.

Please try out following command: meteor help test

In the output you’ll see various options, among those this one:

  --test-app-path   Set the directory in which to create a temporary app used
                    for tests. Defaults to the system's temporary directory,
                    usually /tmp.

Use it :slight_smile:

This works:

meteor test --once --driver-package meteortesting:mocha --test-app-path '~/myTempFolder'

Thank you!
