It is strongly encouraged to take the retirement of $COMMON to review and archive data that may be stored.
HCC will be retiring the $COMMON filesystem on July 1st, 2025 and powering it off shortly after.
Important Dates:
You can move your data to NRDStor, or Attic. In any case, please make sure you have your important data backed up in another location. For large data transfers, it is strongly encouraged to use Globus to transfer your data. The Globus transfer servers for Swan, and Attic provide a faster connection for the data transfer and provide checks on both ends of the data transfer. NRDStor is accessible from the Swan Globus Collection using the /mnt/nrdstor/
path.
The retirement of Common also provides a good opportunity for researchers to evaluate and archive data that is no longer being used.
Data on Common will be removed shortly after the retirement on July 1st, 2025.
For those who are not a part of the University of Nebraska system, please contact hcc-support@unl.edu for instructions.
For those from the UNL, UNO, UNK, or UNMC campus, please follow the steps below.
NRDStor does not have immediate access to everyone with an HCC account. The steps to get access are:
Complete the “Introduction to NRDStor” course.
Wait for the HCC group owner to approve of the request.
Once the HCC group owner has approved the request, HCC will grant access to NRDStor. After access has been granted, please review the NRDStor Documentation.
/mnt/nrdstor/
path.We also have a brief overview of the use of Globus from a prior workshop available here.
All your submit scripts should be modified to not use $COMMON anymore, but the directory where your moved data is stored instead. Additionally, the required line #SBATCH –licenses=common in your submit scripts should be removed as well.
No, when $COMMON is retired the storage media will be immediately erased, and any access to data in $COMMON will be lost. Before the retirement of $COMMON, please move your data elsewhere and create a new Globus Collection following the steps here.
Please contact hcc-support@unl.edu to have this directory moved to $WORK or $NRDSTOR. Please note that in order to use $NRDSTOR you need to first request access to it.
For how to move and recreate existing conda environment, please see here.
Yes, you can submit jobs from the $NRDSTOR file-system. Please note that the $WORK file-system is recommended for running jobs as a high-performance directory.
