Increase \home dir size

Ubuntu @ October 21, 2017   Views:0


I have Ubuntu 14.04 installed on a VPS, the /home is too small for 1 program I want to install/run as its needs 3TB of space to store content, how can I take drive space from /STORAGE without reinstalling the VPS, how can I do it without affecting anything stored on the VPS???

Currently the df shows

There are several possible ways to achieve this but first of all it make me wonder what program is it that needs installing in the Home directory? Does the program give an option of where you'd like it to store the files?
If it is a user that needs the storage space you can change their home directory to /STORAGE using usermod.


usermod -m -d /STORAGE/ username

You can check this worked by:


cat /etc/passwd | grep username

Normally, i'd recommend using LVM to dynamically expand your directories but i fear this would require a re-installation and resetting your partitions (which you wish to avoid) The Ubuntu installation process offers it by default for the root filesystem, though you may not get the options with some VPS providers. Though, I'd perhaps reconsider it if you are expecting to breach 3TB of data in the future.

I hope this helps
