Disk Quota and Usage Command
Under this Baseline Configuration policy, each HPCMP center shall maintain a command named
show_storage. This command allows users to easily identify their quota and usage
information for shared storage areas provided on allocated HPC systems: 1) the home file system
($HOME), 2) the primary scratch file system ($WORKDIR), and 3) any additional
file systems that a Center chooses to report.
Centers may choose to enhance the command's reporting capabilities through the use of additional command-line options.
Default Report Format:
$ show_storage

system /p/home 35953 104857600 12345 -
system /p/work 1285160 53687091200 360 -
The command output shall contain the following information (a hyphen indicates the absence of information for a particular field):
- System - The name of the system.
- Location - The file system corresponding to the reported storage location.
- Disk Usage - The disk storage owned by the user (in KBytes).
- Disk Quota - The disk storage quota, if any (in KBytes).
- File Usage - The number of files owned by the user.
- File Quota - The file count quota, if any.
Because a user's disk usage can change rapidly, centers are encouraged to provide information that is as close to real-time as is feasible.
