Please note this reminder regarding the /work changes scheduled for 29 June and to please recheck the https://portal.tacc.utexas.edu/tutorials/stockyard-work-migration. Currently the "/work" file system is mounted as "read-only" on both the login and compute nodes of all TACC resources. On June 29th TACC will initiate the following switch over: "/work" will transform into a symbolic link pointing to the new /work2 file system. The "/work" file system will then be re-mounted as "/work_old only on each resource's login nodes (only) to allow for last minute file transfers.

If any jobs still utilize any files on /work while running they will be impacted by these changes.

Lonestar5 has hit a substantial failure mode that has affected the core infrastructure. Admins will continue to work to restore service.  The queues will remain unavailable until we are able to restore the compute nodes.  At this time, there is no ETA on the availability of LS5 for compute nodes.
 
In the interim, we've restored filesystem access and have opened the login nodes to allow users to move data between filesystems and utilize Stockyard (/work2 during the migration period) to shift data between TACC resources. We will also shift the timing of the Stockyard migration dates to give users extra time to migrate due to the outage of LS5. Please be cognizant of the fact that /scratch does not have a quota but /work2 does.

ACTION REQUIRED

We are pleased to announce the availability of a new file system (/work2) on new upgraded hardware. Users must migrate any current data they wish to keep from /work to /work2.  Users should complete the migration before 17 May 2021 when /work2 becomes the only work file system mounted on compute resources. As of 19 April 2021, /work will become read-only, and thus all file writes will need to go to /work2. Note that /work is NOT backed up, so you MUST migrate your data to /work2 if you wish to keep it. A more detailed timeline and technical details on how to most efficiently accomplish migration can be found in the  /work Migration and Transition Guide.

Prior to migrating data, users are encouraged to review their data to identify that which can be deleted. The Ranch Archive Facility is also available for data that no longer needs to be in /work but must be retained long term.
