A number of users have run into issues with MMS OnPrem installations due to misconfigured machines hosting MMS backing stores. We should clearly document in the MMS installation instructions that any server that hosts an instance of any of the following should ensure that those machines and the MongoDB data partitions are configured as per the MongoDB production notes:
- MMS Application DB
- MMS Blockstore DB
- MMS Backup Daemon (this one should be made especially clear, since it is not always obvious that the MMS Backup Daemon dynamically spawns mongods and therefore the MongoDB Production Notes also apply here)
Also would be nice to emphasise setting appropriate ulimits, disabling NUMA and disabling THP, in addition to just linking to the production notes.
