Ubuntu "No Space Left on Device" But There Is Tons of Space

ubuntu No space left on device but there is tons of space

It's possible that you've run out of memory or some space elsewhere and it prompted the system to mount an overflow filesystem, and for whatever reason, it's not going away.

Try unmounting the overflow partition:

umount /tmp

or

umount overflow

Error: no space left on device Ubuntu 16.04

you may want to check your inode usage as well:

df -i

it's possible to get "no space left on device" when you have space available, but you're out of inodes.

No space left on device

Such difference between the output of du -sh and df -h may happen if some large file has been deleted, but is still opened by some process. Check with the command lsof | grep deleted to see which processes have opened descriptors to deleted files. You can restart the process and the space will be freed.

As it is full, you may be not able to add a tool to monitor your disk usage, like ncdu

• However, some directories can be cleaned easily :

  check files you need or not

  /tmp
  /var/log/
  

• Snaps are size consuming too, it holds multiple versions of the same package (rollback feature):

Check files before deleting

error: file write error: No space left on device

It depends on where you are trying to do the git add .

As mentioned here:

The /snap mounts come from using software packages installed with Snap.

These utilize loop devices and are usually not writable.

You will get some sort of "No space on device" error when trying to write to any of these locations and that is represented in df -h as showing those mounts as 100% in use.

But in your case, assuming the repository is in /dev/...:

devfs                 392       392         0   100%     679          0  100%   /dev

That means you don't have enough inodes.

Look for files to delete:

for x in /* ; do echo $x ; find $x | wc -l ; done

The goal is to free inode usage or increase the number of inodes.
