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).

Requesting an increase

To request an increase in storage quota, please submit this form: https://tinyurl.com/massive-m3-quota-request. Please wait up to 2 weeks for your request to be processed.

As of 14 December 2024, we are no longer approving allocations on /scratch. This is because /scratch will be retired by May 2025. If you need space, please specify /scratch2 and we will allocate you a space, unless your project already has an allocation. This maybe a good opportunity to clean up your respective /scratch folders.

If we grant your project a /scratch2 allocation, we will offer to migrate your data from /scratch. Note however that the migration will be scheduled accordingly, and during the migration, your access to /scratch will not be possible.

NOTE. If your project already has a /scratch2 allocation prior to January 2025, we will migrate your /scratch folder into a subdirectory oldscratch within /scratch2/<> to ensure there are no file conflicts.
