UPDATE: 11/2/26 - To continue troubleshooting, 2 servers within the research filesystem cluster will be rebooted on 11/4/2026 at 7:30AM. No user impact is anticipated, although slight slowdowns may be noticed as the cluster rebalances during the reboots.

UPDATE: 10/27/26 - The failing hardware has been replaced successfully. We are continuing to troubleshoot the IO error root cause with our storage vendor.

UPDATE: 10/26/26 - A failing hardware component has been identified within the research filesystem while troubleshooting the reported IO errors. That component is scheduled to be replaced by our storage vendor the morning of Tuesday, October 27, 2026. No impact to users or workflows is anticipated, and this blog will be updated as soon as the new hardware is installed.

Following the power outage, ICER is aware of some users seeing IO errors when accessing some files on the research filesystem. We are actively working with our storage vendor to resolve these errors, and will provide an update as soon as we are able.
