EWS Labs, Home Directory Disk Quota


This article provides information about the EWS home directory quota and how to troubleshoot quota issues.

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.  We strongly recommend moving files that are not used for this semester to the free cloud storage provided through your campus account, such as BoxGoogle Drive or OneDrive (sign into these services with your campus account). 

When the EWS home directory is full, below is a list of different symptoms that you may see:

  • The EWS workstation may not allow you to log in.
  • On a Linux workstation, 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. 

Check for and resolve an over-quota issue from Windows

  1. On a personal device, follow this guide to map your Windows home directory but for step 3 use the path below instead - Remote access to your EWS Windows home directory.
    The paths are split by the first letter of your NetID (e.g. If your NetID were frodo123 the path would be \\ews-unity.ad.uillinois.edu\fs2-homes\frodo123)
    1. For NetIDs abc - \\ews-unity.ad.uillinois.edu\fs1-homes\YourNetIDhere

    2. For NetIDs defgh - \\ews-unity.ad.uillinois.edu\fs2-homes\YourNetIDhere

    3. For NetIDs ijkl - \\ews-unity.ad.uillinois.edu\fs3-homes\YourNetIDhere

    4. For NetIDs mnop - \\ews-unity.ad.uillinois.edu\fs4-homes\YourNetIDhere

    5. For NetIDs qrs - \\ews-unity.ad.uillinois.edu\fs5-homes\YourNetIDhere

    6. For NetIDs tuvwxyz - \\ews-unity.ad.uillinois.edu\fs6-homes\YourNetIDhere

  2. Open Windows PowerShell

  3. Using the image below as an example, input the drive letter of the mapped drive and a colon character, then press Enter to navigate to that drive

    1. Navigate to the mapped drive in PowerShell

  4. Copy the following command into PowerShell, then press Enter to check your quota

    1. "{0:N2} GB" -f ((Get-ChildItem .\ -Recurse -Force | Measure-Object -Property Length -Sum -ErrorAction Stop).Sum / 1GB)

    2. Run this command to view your quota

  5. Copy the following command into PowerShell, then press Enter to see the 20 largest files in gigabytes

    1. gci -r -force | sort -descending -property length | select -first 20 fullname, @{Name="Gigabytes";Expression={[Math]::round($_.length / 1GB, 2)}}

    2. Run this command to view the 20 largest files

  6. Alternatively, open the mapped home directory through File Explorer, then 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.

  7. Delete content as needed using File Explorer. When deleting content, press Shift-Delete to permanently delete files, as content in the Recycle Bin counts towards your quota.

Check 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. 
Linux user over EWS 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. 
Linux user under EWS quota

Resolve an over-quota issue from Linux

From a personal device, click here for instructions on accessing the Linux section. When deleting content, press Shift-Delete to permanently delete files, as content in the Trash counts towards your quota.
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. 
If you need assistance locating or removing files, please contact ews@illinois.edu for assistance.
