This question already has an answer here:
I am using Ubuntu 12.04 and I have installed redmine service for users who are working in php and testing. While they are using it, some of them are getting "internal server error".
Actually my home directory space is too small when I checked the properties of redmine. It shows me as 0kB after cleaning cache by typing
sudo apt-get autoclean & sudo apt-get clean.
After that size of the directory increase to 20MB but it is not sufficient for 15 users.
My question is do, I need to increase /home directory size? Is it possible to do it? What are the ways to do that without losing data?
