Quotas & Limits
Cluster-Specific Workspace Limits
Each cluster has different workspace policies and quotas:
| Cluster | Default Lifetime | Max Lifetime | Max Extensions | Storage Quota | File Limit (Inodes) |
|---|---|---|---|---|---|
| bwUniCluster 3.0 | 1 day | 60 days | 3 times | 40 TiB | 20 million files |
| JUSTUS 2 | 7 days | 90 days | Unlimited | 20 TiB | 5 million files |
| Helix | N/A | 30 days | 10 times | 10 TiB | No limit |
| BinAC2 | N/A | 30 days | 5 times | No limit | No limit |
| NEMO2 | 30 days | 100 days | 100 times | 5 TiB per workspace | No limit |
| DACHS | 30 days | 90 days | 3 times | n/a | n/a |
Important notes:
- Default Lifetime: If you don't specify duration, this is used
- Max Lifetime: Maximum duration you can request
- Max Extensions: How many times you can extend a workspace
- Storage Quota: Total space available for your workspaces
- File Limit: Maximum number of files (inodes) you can create
Note: Limits may change. Check cluster-specific documentation for current values.
Grace Periods for Workspace Recovery
When workspaces expire or are released, they can be recovered for a limited time:
- Expired workspaces: Recoverable for 30 days (bwUniCluster 3.0/NEMO2), cluster-specific for others
- Released workspaces: Recoverable until next cleanup cycle (typically during nighttime)
See ws_restore for recovery procedures.
Checking Your Quota Usage
bwUniCluster 3.0, JUSTUS 2
$ lfs quota -uh $(whoami) /lustre/work $ lfs quota -uh $(whoami) /pfs/work9 # bwUniCluster 3.0 specifically
Shows your current usage, quota limit, and available space on Lustre filesystems.
NEMO2
$ nemoquota # Shows all quotas (HOME + workspaces) $ df --si $(ws_find workspace_name) # Check specific workspace
The nemoquota command shows both HOME directory and workspace quotas.
Helix
$ workquotainfo # Shows workspace quota information
BinAC2
$ df # Check available space
BinAC2 has no quota limits enforced on workspaces.
Managing Quota
If you're running low on quota:
- Release unused workspaces: ws_release workspace_name
- Note: Released workspaces count toward quota until cleanup runs (typically during nighttime)
- Immediate deletion: For instant quota relief, see --delete-data option of ws_release
