• Blue Waters Nearline Endpoint Busy

  Created by: gbauer 2018-06-21 23:07:24 (Channels: systemnotices)

  Due to very high demand for data retrieval from Nearline, a pause rule is in effect to allow manual task scheduling. You may submit tasks as normal and they will be run as quickly as possible.

  Tasks submitted to Globus will start in a paused state but will be released to run, at the earliest possible time, based on resource availability.

  We will update this posting as needed.

  We apologize for any inconvenience.

  Contact help+bw@ncsa.illinois.edu with questions or comments.

  Created by: glasgow 2019-04-08 16:27:20 (Channels: unscheduledoutages|systemnotices)

• Blue Waters OSS Failover

  Created by: squaire3 2019-05-12 09:18:53 (Channels: unscheduledoutages|systemnotices)

  Blue Waters is currently experiencing a storage server failover on the OSS file system that began at 8:08 AM CT. As a result, all I/O transactions targeting the affected storage server will block until the failover completes on all clients. A single storage server supplies a small fraction of the file system data and all remaining storage servers continue normal operation. The rest of Blue Waters including the other filesystems are operating normally. Recovery from this type event (without complications) is expected to take less than two hours. The scheduler will be paused during this time.
