This page describes how to manage your storage quota on our Lustre and Panasas storage systems.
Determine quota usage on the HPC/Spear (GPFS)
To determine how much of your quota you are using in your HPC or Spear home directory, login and run the following command:
$ gpfs_quota --home Showing quota information for home dirctory: user Block Limits | File Limits Filesystem type blocks quota limit in_doubt grace | files quota limit in_doubt grace Remarks home USR 73.44G 150G 150G 1M none | 10515 0 0 0 none DSS01.local
To determine how much of your quota your group is using in your purchased research allocation directory, login and run the following command:
$ gpfs_quota [fileset_name] Showing quota information for research fileset: [filset_name] Block Limits | File Limits Filesystem type blocks quota limit in_doubt grace | files quota limit in_doubt grace Remarks research FILESET 3.902T 5.859T 5.859T 6.237G none | 3139994 0 0 17734 none DSS01.local
Note, if you need more details or a different output format (such as bytes), you can use the mmlsquota command (refer to official documentation for more info on this command):
# Print home directory quota /usr/lpp/mmfs/bin/mmlsquota home --block-size=auto # Print research fileset quota /usr/lpp/mmfs/bin/mmlsquota -j FILESET_NAME research --block-size=auto
Determine storage usage on Archival
Currently, we are working on a solution for users to view storage usage on our Archival system. In the meantime, you can submit a support request, and we will provide this information.
Which directories or users are using the most storage space?
Within any directory on any filesystem, you can calculate the distribution of storage space used by using the du command. Warning: This command can take a very long time to run, since it must read the file attributes for every single file in a given directory tree. It is recommended you run this command in a screen session.
du -ch --max-depth=1 /PATH/TO/ANALYZE
