This is a note for my own to remember partitions and recommended sizing that I have been using. Below partition table was created to be inline with various security benchmarks. e.g. CIS/Essential 8

OS Partition - 75 - 80 G Required

/boot - 1GiB
/ - 15 GiB
/home - 10GiB
/tmp - 5GiB
/usr - 15 GiB
/var  - 5 GiB
/var/log - 10GiB
/var/log/audit - 10GiB
/var/tmp - 5GiB
swap - 2G

Satellite
Satellite - 650G - 1 TB required
/var/cache/pulp/ - 20 GiB
/var/lib/pulp/ - 480 GiB
/var/lib/mongodb/ - 60 GiB
/var/opt/rh/rh-postgresql12 - 20 GiB
/var/spool/squid/ - 15 GiB

NOTE: From Red Hat Satellite 6.10, Pulp 3 is being used, MongoDB will be deprecated and it will be consolidated to PostgreSQL.

So from 6.10, the recommendations will be to increase PostgreSQL to 45G and remove /var/lib/mongodb.
