This article explains how to check your filesystem quotas for both your user account and any computing time projects or non-computing groups you are part of.

Checking Filesystem Quotas for Your User Account

You can check your quotas on the filesystems with the r_quota command.

For example:

> r_quota
                        ------------ Blocks ------------- ------------- Files -------------
Object                    used   soft   hard        grace   used   soft   hard        grace
/home/ab123456             53G      -   250G            -    64K      -  1024K            -
/work/ab123456             26G      -   250G            -    67K      -  1024K            -
/hpcwork/ab123456          97G  1000G  1100G            -    47K  1024K  1088K            -
/hpcwork/ab123456(ssd)     17M  1024M  1088M            -      -      -      -            -

Here, the columns in the section Blocks show the used and available storage space, and the columns under Files show the number of files that you have and that you are allowed to have.

Regarding the HPCWORK entries.

The Lustre file system used by HPCWORK manages data storage across both HDD and SSD pools. The HPCWORK entries indicate storage usage as follows:

• HPCWORK (without suffix "SSD") – Represents the total storage usage and number of files across both the HDD and SSD pools.
• HPCWORK (SSD) – Represents only the storage usage and number of files within the SSD pool.

Checking Filesystem Quotas for Computing Time Projects or Non-computing Groups

You can also use the following command to check the filesystem quotas for a given computing project or non-computing group:

r_quota -u <project-id>

Note: that this works only if you have UNIX read permissions on the involved directories. All quotas are so-called tree or directory quotas. All files stored under a directory are accounted, no matter what their UID and GID are, i.e. even files that do not belong to you count towards your quota usage if they reside in your home/work/hpcwork directory.
