The RCD team has scheduled a maintenance window to perform work on the Palmetto Cluster, Indigo Data Lake, and other systems at the end of the Spring semester.

This work will begin on Saturday, May 31st, 2025, at 9:00 AM. While maintenance work is in progress, all RCD services will be unavailable.

During the maintenance window, we plan to complete the following:

• Minor OS Upgrades
• Networking Maintenance
• System Testing and Benchmarking

There are no plans to purge scratch space during this maintenance, but users should be mindful that scratch space is never backed up and critical files should always be stored on home or project storage.

Users should expect that services will be restored no earlier than Friday, June 6th, 2025, at 5:00 PM and should monitor their email for updates from RCD.

Please feel free to reach out to RCD with any questions or concerns that you have about the maintenance work by submitting a support ticket – we would love to hear from you!

The Research Computing and Data (RCD) team plans to host a Town Hall event on April 23rd, 2025 at 3 PM to share some imporant updates with the community.

Below is a summary of what we will cover:

• changes to RCD personnel
• plans for the Spring 2025 maintenance window
• new compute nodes added to Palmetto 2
• upcoming Granite environment for CUI, PHI, and NIST 800-171 (NIH) research
• updates to ReDCAT leadership
• updates to Indigo storage expiration notifications
• rollout of new Job Defense Shield tool

This event is open to all Clemson University students, faculty, and staff. Please register online if you plan to attend.

For those unable to join us, we will post the slide deck and recording here after the event. Come back for updates!

There will be a partial outage on February 24, 2025, at 9 AM. We expect the maintenance to take approximately one hour to complete. 

We have identified an unexpected issue with one of the network switches in Palmetto, requiring us to reboot the switch. This will only affect a subset of compute nodes on Palmetto. 

We are preventing new jobs from landing on the affected nodes to minimize disruptions. Jobs currently running on these nodes will be allowed to continue until the maintenance period begins. Users will still be able to log in, submit jobs, and use other RCD services, such as Open OnDemand. However, please keep in mind that you may experience extended wait times due to the affected compute nodes. 

We have chosen to perform this emergency maintenance as soon as possible to avoid a larger, unplanned outage. We apologize for any inconvenience this may cause. 

If you have any questions, please reach out to us by submitting a support ticket.

We are replacing our old Data Transfer nodes with new Data Transfer nodes on Tuesday, 02/11/2025 at 9:00 am. We expect the replacement process to take about 2 hours.

There will be no change to the Data transfer node names and details. Users will not have to update any details on their end.

Active SCP/SFTP transfers will be interrupted during this time. Globus transfers should be able to restart after the new nodes come online.

Please reach out to us if you have any questions or concerns by submitting a support ticket.

RCD and Duke Energy have completed the planned maintenance work for this week. All RCD services are now available to users again.

For details about the completed work, see the RCD maintenance post and the Duke Energy maintenance post.

If you have any questions about this maintenance work or are experiencing issues, please do not hesitate to submit a support ticket to let us know.

Before the start of winter break, we wanted to remind you about our upcoming maintenance and let you know about a scheduled power outage that will affect Palmetto.

Summary of Outage Dates:

• RCD Maintenance: Friday, December 20th
• Duke Energy Maintenance Part 1: Monday, December 23rd
• Duke Energy Maintenance Part 2: Friday, December 27th

We had previously announced our Winter 2024 maintenance plans, which will occur this Friday (December 20th) between 9:00 AM and 11:59 PM. See the Winter 2024 maintenance blog post for more details.

Additionally, Duke Energy has recently notified us that they will need to perform maintenance on power infrastructure at the data center during the holidays next week. This is necessary to resolve unmitigated impacts due to Hurricane Helene and ensure our energy supply remains stable. This maintenance will cause a partial power outage affecting some parts of Palmetto.

They will complete the power maintenance in two parts, with the first scheduled for Monday, December 23^rd and the second planned for Friday, December 27^th. We expect the cluster to be down starting at 7:00 AM and for power to be restored no later than 6:00 PM on both dates.

The same notes regarding job cancellation, job queueing, and scratch space as our other scheduled maintenance apply (see the Winter 2024 maintenance blog post for details).

As always, if you have any questions about this maintenance work, please submit a support ticket.

The RCD team wants to remind everyone about our upcoming Winter 2024 maintenance window on December 20^thbetween 9:00 AM and 11:59 PM.

While maintenance work is in progress, all RCD services will be unavailable, including Palmetto 2, Open OnDemand, RCD GitLab, RCD Mattermost, and the Indigo Data Lake. Any batch jobs submitted before maintenance that cannot be completed in time will be held in the queue, but all interactive jobs will be canceled. Data transfers will be interrupted, so please complete them ahead of time to avoid possible corruption.

During this maintenance window, our engineers will work on the following:

• Changes to the research network configuration to improve performance. Making these changes will disrupt connections to Indigo storage, so they must be completed during a maintenance window.
• Installation of software updates for RCD GitLab.
• There are no plans to purge scratch space. However, users are encouraged to ensure they do not have any valuable data stored in scratch space, as always.

If you have any questions about this maintenance work, please submit a support ticket.

Palmetto 1 will be taken offline on October 31, 2024. As part of this transition, we will move Palmetto 1 hardware resources into Palmetto 2. 

There will be no change to data in users’ home directories when Palmetto 1 is taken offline.

If you do not currently have access to Palmetto 2, you can obtain access by following the Account Setup procedure.

To help you get started with Palmetto 2, we offer a few training/onboarding options:

• New Onboarding Training
• Workshops
• Migration Guide
• Office Hours

If you encounter any issues or have any questions, please do not hesitate to reach out to us by submitting a support ticket.

Thank you for your understanding and cooperation during this transition.
