Right. So, clearly, initdb thinks it was told to initialize
/mnt/postgres/data. Looking back at your original trace,
we see it being called like this:
+ runuser -l postgres -c '/usr/pgsql-10/bin/initdb
--pgdata='\''/var/lib/pgsql/10/data/'\'' --auth='\''ident'\''
--data-checksums -E utf8 --no-locale -D /mnt/postgres/data'
^^^^^^^^^^^^^^^^^^^^^
So evidently that won out over the earlier --pgdata switch,
which is unsurprising. But it definitely looks like this
service script is confused, or else you've put a -D switch
into some option that's not supposed to contain that.
The Postgres project as such doesn't distribute systemd
service scripts, so you'll need to take this up with
whoever created the script you're using.
