Checking Usage

Tip

HMS Research Computing has released a new tool for checking personal and group storage utilization and limits, called quota-v2. It retrieves more comprehensive information than the previous quota tool, executes faster, and runs on all O2 nodes (login, compute, and transfer cluster).

More information can be found in the quota-v2 documentation.

You can use the quota and du commands to check filesystem usage.

...

You will see a number representing your individual storage usage in your /home directory on the "user" line above the 100GiB quota on the "directory" line. If you’re using /n/scratch3, you’ll see a line for your personal usage in your sub-directory within /n/scratch3/users. Some labs/cores have group directories under /n/scratch3, so that information will be reported if you’re a member of such a lab or core.

Note: It is against RC policy to artificially refresh last access time of any file located under /n/scratch3.

...

You can delete a whole directory with a command like rm -rf dir. Please be careful when using a command like this: you could delete all of your files!
