If you have enough storage on your instance and you are still seeing the error in the UI, which is preventing the sync action to successfully occur, please run the following steps:
1. Copy the mission-control.db.properties.template, from the etc folder, to mission-control.db.properties.
2. Uncomment lines matching properties you want to change, and update their values --> drconfig.space.detection.disabled=true
3. Relaunch cluster nodes.
Before taking these actions please first make sure that there is in fact enough space on the Artifactory instance in question.
