@simenon, would you mind contributing the fix? You can find the doc here: https://github.com/pulp/pulpcore/blob/cd2b35fdfa87a45df8722f37cb8a1b6a8d34abc1/docs/user/guides/reclaim-disk-space.md?plain=1#L14. It should have the structure similar to https://github.com/pulp/pulpcore/blob/cd2b35fdfa87a45df8722f37cb8a1b6a8d34abc1/docs/user/guides/create-domains.md?plain=1#L59, without (j and with an empty line).
