[Resolved] Cluster inaccessible

Posted by on Monday, October 1, 2018 in Cluster Status Notice.

Update, 2pm:

The cluster is accessible again. Thank you for bearing with us and we sorted through these issues.

We were able to successfully upgrade the cache on three of our six GPFS storage appliances. The third one is where we encountered issues. A hardware problem prevented us from booting the device cleanly until an hour ago or so.

Upgrades on the three remaining devices will be scheduled on a future date.

The good news is that the successful upgrades took place on devices where we have been seeing the most I/O bottlenecks in recent weeks, so we are hopeful that users will notice a difference.


Original post:

We encountered problems during our scheduled maintenance this morning and as a result the cluster (both CentOS 6 and 7 environments) is now inaccessible. We are working on it and will keep everyone posted.
