Storage Quotas

Each user has a default fixed 25 GB home quota. The Scratch storage tier provides 2 TB per project, shared by all its members.

Storage area	Current limit
Home	25 GB per user
Project scratch (Scratch tier)	2 TB per project, shared by its members

Storage is not backed up. See the Data Retention Policy for deletion after project completion or a period without project membership.

Check Home Usage

To view your home directory:

echo $HOME

To check your home storage usage and quota (25 GB per user):

lfs quota -h -p $(id -u) /nfs

Check Project Usage

Your project's shared scratch directory is /nfs/scratch/<slurm_account>. For example:

/nfs/scratch/alloc-pr-2026-10-2

To view its storage usage and quota, replace the example account with your project's Slurm account:

SCRATCH=/nfs/scratch/alloc-pr-2026-10-2
lfs quota -h -p $(lfs project -d "$SCRATCH" | awk '{print $1}') /nfs

The scratch directory is shared among the project's authorized members. All members share the same 2 TB storage quota.

Multiple Projects

Repeat the project quota query for each project’s scratch directory. Each project has its own shared allowance; the allowances are not pooled, and your home quota does not increase with project membership. Store data in the directory for the project it belongs to. Selecting a Slurm account with --account does not move files or select a storage quota.

Data Retention Policy

User data is not backed up. Keep independent copies and transfer files before access expires.

Data	Deleted after
Project scratch	3 months from the project's end
User home	6 months without being on any project
