You may have noticed the release notes for the 2023.03 and later versions of Workbench contain the following:
- When the Job Launcher is enabled, the Local plugin can now be configured to use “external” load balancing, which removes the need for the
scratch-pathto be on shared storage (rstudio/launcher#42, rstudio/rstudio-pro#3770)
The link for this can be found here:
https://docs.posit.co/ide/news/#posit-workbench
What does this mean?
Previously, load balancing with Local Launcher required the use of an NFS shared directory for the Local Launcher nodes to discover each other. This change adds a new external balancing method that Workbench will use to provide information about nodes that are available in a cluster. This allows us to reuse all of the existing discovery mechanisms in Workbench nodes without having to duplicate this logic or add database support to the Local Launcher.
Please note that you will need to still keep the launcher.local.conf file, This means that you will need to edit your /etc/rstudio/launcher.local.conf configuration file to contain the below.
# /etc/rstudio/launcher.local.conf
#scratch-path=/mnt/rstudio-server/Local
load-balancer-preference=externalFrom there, a restart of the Workbench and launcher services is required:
sudo rstudio-server restartsudo rstudio-launcher restart
