Users urged to migrate to Casper as other DAV clusters near end of life

November 30, 2018

Users should migrate their data analysis and visualization (DAV) workflows to the new Casper cluster soon if they have not already done so. The Geyser and Caldera clusters will be decommissioned on December 31 and are experiencing more frequent hardware failures as they approach end of life. Several Geyser and Caldera nodes have already suffered irrecoverable hardware failures. They have been removed and will not be replaced.

During a scheduled maintenance downtime on December 11, the execdav command will be updated so it defaults to assigning Casper nodes for use in interactive jobs. When Geyser and Casper are decommissioned, the execgy and execca commands will be removed. Keep an eye out for more information about the December 11 downtime in upcoming Daily Bulletins.
