Storage quotas
M3 does not have unlimited storage capacity. Therefore, we enforce storage quotas on the different filesystems. A storage quota is the maximum amount of disk space you can use on a given filesystem. The below table summarises the quota available to each user (in their home directory) and project (note each project gets its own quotas).
| Directory | Default quota | Can you increase this? |
|---|---|---|
Home ~ | 15 GB | No |
Project /projects/ab12 | 500 GB | No |
Scratch2 /scratch2/ab12 | 3 TB | Upon request |
Requesting an increase
Your default Home directory has:
- a 15G Soft Limit
- a 20G Hard Limit
If you exceed your Soft Limit for more than a week, you will find you can not write to the file system until your disk usage falls below the Soft Limit
user_info will only show the hard quota.
Before requesting a large increase
Our Lustre system if quite full, and approaching a point where its size will affect its performance. Large quota requests (e.g. 10+TB) will be reviewed more closely, and will only be given for temporary periods of time e.g. 30 days.
If you have any further enquiries, please contact us at help@massive.org.au.

As of 10 April 2025, we have retired the /fs03 file system that used to host /scratch.
All your /scratch folders have been migrated to:
/scratch2/<> or if your project already has a /scratch2 allocation prior to April 2025,
we will migrate your /scratch folder into a subdirectory oldscratch within /scratch2/<> to ensure there are no file conflicts.
