IRA Data Warehouse Finance chain failure
Resolved - IRA for the Finance subject areas should be up-to-date (as of overnight processing).

Investigating - The Data Warehousing Finance update failed overnight. The failure occurred within the Labor Distribution area. As such, the following areas are stale at the moment: HR/LD, Procurement, AR and Facilities. NOTE: The GL and OGA systems finished, so those areas should be ready. We are investigating the cause and working to resolve the issue and complete the process at this time. Updates will be posted when we know more.

Discovery Cluster Node Outages
Resolved - The hardware has been replaced and the affected nodes are online.

Identified - Due to a switch outage several of our HPC nodes are in a down state. We have ordered the replacement part and estimate the nodes to be restore after lunch tomorrow.

Dell PowerScale OneFS upgrade
Completed - Weve completed our update.
Aug 26, 15:06 EDT
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Aug 26, 10:00 EDT
Scheduled - Research Computing and Data will be installing routine firmware and software updates on the Dell PowerScale system which provides network file services to the campus. This includes DartFS, ThayerFS, and others.

These reboots are staggered so that the service never goes down, but any clients connected to a node that is in the process of rebooting obviously need to reconnect to a different node.

NFS clients running Linux do this automatically and seamlessly.

Unfortunately, the SMB protocol does not allow for the same kind of seamless transition to a different node. The actual SMB client behavior depends on the operating system (Mac, Windows, or Linux) and the application using the storage.

In general, Windows systems and applications will recognize that the connection was interrupted and automatically reconnect to a different node after just a few seconds.

Mac and Linux SMB clients will keep trying the same node for longer. After a timeout period, they declare a network error. Some applications will try to restart the connection from scratch and that will work. Most commonly, Mac users can simply reconnect from their saved list of favorite servers.

Please note that if you were actively using any of these file servers during the entire maintenance window you would experience at least one such disconnection and probably several as we cycle through the nodes to reboot them all.

We will post an update here when the work is complete.

Discovery Cluster Scheduler Disruption
Resolved - We have resolved the issue though we are continuing to monitoring our systems.
Aug 25, 08:54 EDT
Update - Discovery is now stable. We are waiting for jobs to finish on about 30 more nodes so we can reboot those and get them ready for new jobs.  Until those 30 are reintegrated, you may see increased wait times in the queue for resources to be free.
Aug 21, 13:58 EDT
Monitoring - We experienced a large cluster issue while updating the Slurm database host to a newer version.
This resulted in some jobs becoming stuck in the COMPLETING (CG) state and caused broader job instability.

We have since upgraded the cluster to the same Slurm version as the database and are rebooting affected
nodes to clear jobs stuck in the CG state. The cluster is recovering, and stability is improving.

We appreciate your patience as we continue working to fully resolve the issue and return the cluster to a steady state.

Please check the status and results of your recent jobs. If you experienced job failures or lost compute time as a result
of this outage, please reach out to research.computing@dartmouth.edu.

Where helpful, we can temporarily increase your
available resources to help account for lost compute time.
Aug 21, 10:21 EDT
Update - Weve applied an update to the scheduler. All new jobs will begin as normal however as running jobs finish, we will need to reboot compute nodes.
Aug 21, 09:00 EDT
Update - HPC systems remain operational but degraded due to an ongoing issue. Troubleshooting is paused for tonight and will resume tomorrow morning. We appreciate your patience.
Aug 20, 19:12 EDT
Identified - The scheduler on Discovery(Slurm) is behaving erratically and we have a ticket open with the vendor. We will update when we know more.
