• Did you know there’s a 256GB quota for all /home directories?

  This policy will be fully enforced in the coming weeks. This requirement is needed to manage space and load for /home. Home directories should primarily be used to set up scripts, small software applications, and environment variables across the cluster. To that end, we will be enforcing a hard quota of 256GB. A consolidation of all /home directories to one storage device will take place this year. The exact date will be advertised but please contact me or [email protected] with any other questions.

Note: If you are currently over the limit, you will have time to move data but start moving (or removing) data now.

• Did you know we have about 950TB of storage right now?

  This includes the Lustre filesystem (/lustre, 698TB) and the MemexNFS filesystem (/work, /scratch, /share/apps, and /home ~ 252TB). Check out our login banner (see "Mountpoint Information") to see how each filesystem should be used.

• Did you know we now have a Memex Globus endpoint, "cisuser#carnegiescience"?

  Globus transfers are typically much faster than our command line option. Instructions on how to setup and use Globus on Memex is in our FreshService ticketing system (Solutions --> Computation).

• Did you know you can check disk usage in the following ways?

  For most users, the new command

    $ zquota 
  

  will show your /home usage and your group’s usage for /work/DEPT. Shared directories such as /share/apps, /scratch, and /lustre usage can seen by the ‘df’ command. For example:

    $ df -h /lustre /share/apps /scratch
  

  shows usage for all three filesystems. Of course, other commands like $ du -sh /home/username/directory/ for directories or $ ls -Shl filename for files can be used as well.
