When I do show collections in using configDB it looks as it is missing some collections.
For e.g. actionlog, databases are not in the output as seen.
I also checked https://docs.mongodb.com/manual/core/sharded-cluster-config-servers/ and it does mention “databases” as one of the collections.
This is how sh.addShard looked
And this is the status of sh.status()
“collections” collection in config db also not showing details on collections that have been sharded.
Could this be the reason of “database” collection missing?
Please suggest what can be the reason for it.
