This outage is required to facilitate an upgrade of the high-speed, Lustre filesystem software and implement a new management structure for storage services.
Following this outage, all user directories in $CENTER1 will be located in subdirectories under the project(s) that you are a member. Each project will receive a 1 TB, unpurged quota. User directories currently in $CENTER1 will be moved to the new $CENTER1 project directory.
On July 27th there will be maintenance on the $CENTER1 file system to address slowdown and errors involving file operations. The system will need to be taken offline to apply a patch that we anticipate will resolve these issues. Jobs that are scheduled to run during this downtime will stay in the queue and be run after the downtime reservation. The Chinook HPC cluster and the Linux workstations will be affected by this outage.
We are currently investigating issues with copying and creating files on $CENTER1 reported by users. Users may see an error stating "No space left on device" while trying to create, copy, or download files to $CENTER1, and may have to wait and retry the operation. RCS expects that fixing this issue will require an outage and we will update users with further information and when this outage will be scheduled.
Chinook00 is being rebooted on July 12, 2017 at 3pm AKDT. This should be a brief outage, and logins during the time chinook00.alaska.edu is offline should be redirected to the other login nodes.
Due to continued system troubles from the June 28 unplanned power outage, some web services may be experiencing glitches. RCS is currently troubleshooting to restore services.
