2018-10-15: Rolling updates on HCC cluster resources
Category:
General AnnouncementSecurity updates are being applied to the Crane, Sandhills and Tusker clusters. The rolling updates are applied as soon as the oldest job on a worker node finishes, potentially keeping new jobs from starting until the updates are applied. This will cause pending jobs to report lengthened wait times in queue with a reason of "Priority," "Resources," or "ReqNodeNotAvail, UnavailableNodes," particularly if the requested time by the job exceeds the time before the worker nodes' resources drain. Shorter jobs will likely have more resources to run on in the next couple of days, as long as they finish before the oldest job completes on draining worker nodes.
All updates will be finished by 10PM Friday, October 19th.
