EWS Labs, Home Directory Disk Quota

Description of the home directory quota that is applied to home directories.

EWS users are given 10 gigabytes of storage that is shared between EWS Windows and Linux. If you fill up your disk space (or "quota"), you won't be able to write additional files to your drive and the system may respond oddly. Below is a list of different symptoms that you may see:
  • On a Linux machine, your computer may be complaining about problems locking the .ICEauthority file. 
  • After logging in, programs might complain about not being able to write their files to your drive.
  • You may not be able to download any new files on Windows or Linux.
  • Windows computers may not allow you to modify or remove existing files.
  • The computer may not allow you to log in. 

Checking your quota from Windows

Your home directory will be mounted to the "U:" drive of any EWS Windows workstation. Simply browse to "Computer" on the right side of the start menu (or search the start menu for "This PC" on Windows 10) and look for the U: drive. Your available quota will be displayed below the utilization bar.

Checking your quota from Linux

Your home directory will automatically be mounted and assigned as your home directory to any EWS Linux workstation. Log into an EWS Linux workstation and open Terminal

Type quota <your_netid> and press enter

The following is an example of what an over-quota account looks like. The first number is the space used. The "*" next to it indicates you are over your 10 GB quota, which is the second number. If the number under the "blocks" column is greater than the number under the "quota" column, you have exceeded your quota.

The following is an example of a user that is under the quota limit. Notice the absence of the "*" and the "blocks" column is less than the "quota" column.

Resolving an over-quota issue


If the EWS workstation allows you to log on, you can potentially resolve the issue yourself. The easiest quick fix is to empty your Recycle and Trash bins (on Windows and Linux, respectively) to clear any files that have been removed but not permanently deleted yet.

To find large files in your Windows drive, you can right-click a folder under your home directory and select "Properties." This will show you the size of every file and folder that is stored within that folder -- you can use this to narrow down which folders may contain the files using most of your storage space. 

To find large files in your Linux drive, run the following command in the Terminal:

find ~ -size +100M -ls

This will give you a list of files that are over 100 MB. You can remove them with the rm function. Try deleting old files from classes you are no longer enrolled in, or things that you no longer need.
