The myquota command shows how much storage space and how many files you're using in your SeaWulf directories. Since SeaWulf enforces limits on both storage size and file count, this command helps identify issues that lead to quota or disk errors.
Basic Usage
Run myquota with no options to view your usage across your home, scratch, and any project spaces you belong to:
[NetID@login2 ~]$ myquota
== NetID-home ==
Filesystem GB quota limit | files quota limit
mmfs1 6 20 20 | 61172 204800 204800
== NetID-scratch ==
Filesystem GB quota limit | files quota limit
mmfs1 1 20480 20480 | 204 10000000 10000000
== DoeGroup ==
Filesystem GB quota limit | files quota limit
mmfs1 3957 5120 5120 | 2038373 10485760 10485760
In this example, the user’s home directory has used 6 GB out of 20 GB and 61,172 files out of 204,800 allowed.
Checking a Specific Directory
To check a specific directory, add its name after the command:
myquota <netid>-home – your home directory
myquota <netid>-scratch – your scratch directory
myquota ProjectName – a shared project space (e.g., myquota DoeGroup)
Replace <netid> with your actual NetID in lowercase. For example, if your NetID is ssperrottet:
myquota ssperrottet-home
Understanding the Output
Each myquota entry displays two sets of limits:
- GB / quota / limit – total storage used and maximum allowed
- files / quota / limit – number of files used and maximum allowed
Most directories have identical soft and hard limits, so you can treat them as a single boundary.
When to Use myquota
- If you receive a “disk quota exceeded” or “no space left on device” error
- Before transferring or generating large datasets
- When troubleshooting project space issues shared with others
