At IU, how do I use my space on the Data Capacitor?

Note: In examples that follow, replace projectname with the name of your project and username with your Network ID username.

At Indiana University, the Data Capacitor is mounted on Big Red and Quarry.

The mount point for project space is /N/dc/projects/projectname.

The mount point for scratch space is /N/dc/scratch/username.

The mount point for WAN space is /N/dcwan/projects/projectname.

To determine the amount of space in terabytes (TB) available on the Data Capacitor, use: df -h

This will list the amount of space available and used for all filesystems mounted. Look for the mount points /N/dc and /N/dcwan to see the amount of space available on the Data Capacitor. The -h flag tells df to use human readable formats for the space available and used (in this case T for terabytes).

To determine the amount of space you're using in your project directory, use:

To view the permissions for your project directory, use:

To view the permissions for your scratch directory, use:

The output of the ls command will display the permissions for the directory, as well as the owner and group of the directory.
