Section Number and Name:

3.1. Upgrading Satellite Server
Before You Begin

Describe the issue:

The documentation warns customers that /var/lib/pulp/published/ may double in size during the migration, but it doesn't tell customers that docker images will be moved to /var/lib/pulp/media, that this directory could become large, or how to predict the eventual size of that directory. This isn't mentioned by the output of the command "satellite-maintain content migration-stats" either.

This issue affects customers who have mounted volumes at /var/lib/pulp/published rather than at /var/lib/pulp, because in this case /var/lib/pulp/media will spill over into the /var volume.

Suggestions for improvement:

• mention that docker images will be moved to /var/lib/pulp/media
• give customers a command to evaluate how much storage their docker images take up on disk prior to the migration
