Data Management FAQ

How much storage space do I have left/used?

Keep track of your storage usage by logging into Midway clusters and running the quota command. This handy tool on the Midway 2 and 3 ecosystems provides you with all the corresponding information you need.

I'm over quota (expired quota); what do I do?

If you find yourself over quota (expired quota), fret not! Follow these steps to get back on track:

Identify whether your quota is expired due to the number of files (files) or total file size (blocks). If it's due to the number of files, consider zipping some files to count as one, rather than a large set of small files. If your quota is expired due to file size:

  1. If /home is expired, move your files to /scratch or /project/drpepper. Some users may also utilize /dali/drpepper, /beagle3/drpepper, /cds/drpepper, /cds2/drpepper, or /cds3/drpepper.
  2. If /scratch is expired, relocate your files to /project/drpepper. Similarly, some users may utilize /dali/drpepper, /beagle3/drpepper, /cds/drpepper, /cds2/drpepper, or /cds3/drpepper. Alternatively, delete unnecessary files.
  3. Request your PI to submit a research allocation request to obtain more storage. If the standard research allocation is insufficient, consider supplemental research allocation for temporary storage expansion.
  4. Ask your PI to purchase additional storage via the cluster partnership program.

Why can't I write files into my home directory?

Encountering errors while writing files typically indicates that you're over-quota. Ensure that you're within quota limits in terms of both size and number of files using the quota command.

How do I increase my storage quota?

Expand your storage capacity through the Cluster Partnership Program. Alternatively, request additional storage as part of a Research II Allocation or Special Allocation.

How do I share files with others?
