base/ is the directory you need to look in. I'm guessing it is only 
going to show the oid/ for the three db's above and  pgsql_tmp/

For more info on this see:
https://www.postgresql.org/docs/10/storage-file-layout.html

The below looks like the RH package installed data directory. Also looks 
like it either has never had initdb run against or the files where removed.

I thought you said you had copied in data directories from the other 
nodes, did I remember correctly?
