[katello] used all available space

I've had my Katello server running for some time (months) and checked on it last week and it was down complaining about Mongodb not starting.

A closer look revealed that my available HDD space was exhausted and that was preventing mongo to come back to life.

So I need to go into the pulp directory now and delete some old repo synchronizations to save some space. Would you know where can I delete these old repo synchs?

I was under the impression that a default repo overwrites itself with each replication and that the only way to maintain old content is to create a custom view. Apparently I was wrong as this server had plenty of space after I synched all the repos the first time around.

Any tip is welcomed.
