"No space left on device" error when there should be space

I have a droplet that has been collecting some data for me, I now want to run a python script, which fails as follows:

out = open('data.tsv', 'w')
IOError: [Errno 28] No space left on device: '/data.tsv'

The problem is, I think there should be plenty of space. Running df -h produces the following:

Filesystem                 Size  Used Avail Use% Mounted on
udev                       235M  4.0K  235M   1% /dev

Actually, I believe this may be an issue of you telling it to delete files, but the system hasn’t actually done so, but the pointers are gone.

Run this:

lsof|grep delete

If you see a lot of things return, the simplest solution would be to reboot. It will clear up those files when it restarts.

I’m not great when it comes to coding but here’s a couple of things to check until a programmer comes along.

Sounds like a permissions issue.
1 ) Does the file you are trying to write to exist?
2) Are you going to run the script manually each time?

Sounds like if the file exists and you are manually running the script, you don’t have the correct privileges to write to the file.
