The droplet on Digital Ocean for my Rails project did not have any space left.

Here is how I created space by deleting files.

1. Login using SSH and check available space using $df -h

2. Check disk usage using du command.

$du -h | sort -h

This will list the directories showing the biggest size at the bottom.

I noticed that ./project/shared/log folder was consuming 3.3GB space.

3. In another terminal window, I opened sftp session.

4. sftp>cd project/shared/log

5. Now delete files using rm command.

sftp>rm uat1.log

Everything was fine after that.
