We have received reports of compute jobs failing due to I/O delays during at least 3 different periods in as many days. The I/O delays seem limited to the DORS sub-system of the GPFS storage. We are looking through the usage logs to identify the cause, but our initial assessment is that these jobs are heavily using a large number of files in a manner that our data tiering policies don’t expect. If you have experienced jobs repeatedly failing, please open up a helpdesk ticket detailing the event, the time frame, and the path of the files you are using.
