DATE CORRECTION: Stockyard Maintenance will be June 17th - 19th 2025

Starting June 17th, TACC will be performing routine maintenance on all systems that utilize Stockyard. Please note, as Stockyard is connected to all systems, any and all systems will be impacted by this maintenance outage:

Frontera

Lonestar6

Stampede3

Vista

Updates on $WORK are expected to take longer than the typical, single day maintenance window. In order to reduce the impact on users, we will be unmounting Stockyard on all systems. All other filesystems will remain available. In order to continue running during this maintenance period, you must migrate all necessary files from $WORK to $SCRATCH.

Files and workflows must be moved prior to June 17th. Once the outage begins, Stockyard will be entirely inaccessible until the end of maintenance.

The Stockyard maintenance window will comprise three sections. Details are below.

Day one of Stockyard maintenance will commence on June 17, 2025 at 08:00. Any and all systems will be placed into a maintenance window to disconnect $WORK, and Stockyard administrators will begin their tasks. Additional maintenance activities may be performed as well on affected systems. Once $WORK has been disconnected and any additional maintenance finished, said systems should resume operations by 20:00, provided that they're able to function without $WORK being active.

Day two of Stockyard maintenance will be ongoing. As production clusters return to production, systems will be fully available except for the /work filesystem.

Day three of Stockyard maintenance should be completed. Once confirmed, systems administrators will be notified and $WORK will be mounted across all systems.

Once maintenance is complete, users may return to their typical workflows that make use of Stockyard. If maintenance is completed early, an update will be posted at that time.
