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's two filesystems (DC and DC-WAN) are mounted on Big Red and Quarry.
The mount points for project space are:
/N/dc/projects/projectname /N/dcwan/projects/projectnameThe mount points for scratch space are:
/N/dc/scratch/username /N/dcwan/scratch/usernameTo 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 the
DC and DC-WAN filesystems, respectively. 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:
du -sh /N/dc/projects/projectname du -sh /N/dcwan/projects/projectnameTo view the permissions for your project directory, use:
ls -al /N/dc/projects/projectname ls -al /N/dcwan/projects/projectnameTo view the permissions for your scratch directory, use:
ls -al /N/dc/scratch/username ls -al /N/dcwan/scratch/usernameThe output of the ls command will display the
permissions for the directory, as well as the owner and group of the
directory.
