Users are able to check quotas for the Isilon storage (home and project directories) and the Panasas scratch storage using the iquota tool

Your user quota (home directory - /user/<username>): 



NOTE: If you do not see a quota here, you will need to specify:

iquota -f /user/<username>

Your group's quota (output will show all groups you are a member of): 


iquota -g

Or both user and group quotas on Isilon and Panasas:


iquota -u -g

NOTE: If you do not see a quota for your home directory, you will need to specify:

iquota -u -g -f /user/<username>

iquota usage:

The iquota command has much more built into it than former versions.  Use iquota -h to see all the options.  


NOTE: You will need to get a kerberos key before running the command, with:  kinit



   iquota - displays users' disk usage and limits. By default only the user quotas are printed.

Do you have two-factor authentication enabled?

There is a known bug in the Red Hat authentication system that prevents the usage of
kinit. Until this is resolved, users with two-factor authentication enabled are unable to use the iquota commands. We are in the process of building this information into Coldfront. In the meantime, please submit a help ticket and a CCR staff member will provide quota information for you. Thank you for your patience!

Calculating disk usage at the Linux command line:

Knowing your quota and how much of it you've used is helpful, but often we want to know where the disk usage is actually taking place.  You can run this command to calculate the total size of each sub-directory and then sort it from smallest to largest.  You will only be able to run this where you have permission to read files.  So it's appropriate to run in your home directory:  /user/[ubit_username] or your group's project directory.
