Planned Outage - Arrêt planifié


Starting Thursday, June 23rd, 2022, at 9 am ET, the Graham cluster will be unavailable to all users as we perform an upgrade of the project file system. All running jobs will be terminated but queued jobs will remain. Queued jobs that would extend past the beginning of the outage will not be allowed to launch until after the maintenance.  The work will be completed by Thursday, June 30th, 2022 at 10 am.

Please watch https://status.computecanada.ca for updates on the availability of Graham and all other national systems.

We are upgrading the project file system to provide better overall performance. The upgrade is not expected to cause data loss; however, as with any file system maintenance, issues could potentially arise. Should issues arise, we could recover files from the daily backups.

This outage will impact the cluster, login nodes, visualization nodes (VDI) as well as data transfer nodes (DTN). There will be no impact to the Graham cloud.
