 +==== vdesk service is rebuilt ==== 
 +I expect the service to stay up, mostly. Nodes will be going up and down depending on when they get rebuilt so expect disconnections if you HAVE to use this service. 
 + 
 +  * All login nodes upgraded without downtime of the service. 
 +  * Short amount of downtime expected when upgrading the vdesk load balancer.

 +  - Rebuild of all nodes to 20.04 
 +  - user to slurmdbd sync took longer than expected.
