The HPC team is looking into issues with the sharedstorage02.hpc.uiowa.edu/lc-rs-storage05.hpc.uiowa.edu system which became unavailable at approx 1:30PM on 4/29.
We will update this page when things have stabilized.
2:25PM 04/29 Update: We have identified the problem to a failed cache device in the storage pool. We have offlined this device and are evaluating whether or not we will perform a replacement of this device (there are 2 in each storage system) or schedule a maintenance window to replace this device.
The system is back online as of 2:30PM and we intend to schedule an off-hours maintenance window to replace the faulty device.
