Satellite 6 requires large amounts of storage in the /var/lib/ partition mostly in /var/lib/pulp for content.

It is common that a sync is started and fills up /var but the user doesn't really know why syncs are failing or when they are getting close to the limit on that filesystem.

Ideally Satellite 6 would monitor and warn when a sync starts that it will fill up /var/lib.  We have size calculations available when syncing so it could be possible to sum up the total # of running syncs and warn and eventually pause the sync when the limit is close (within some configurable criteria).

This would allow the admin to add more space and then resume the sync.
