Can't change MongoDB default DB path I know there are multiple questions on the same issue and I followed them but not sure what is happening here. First of all I am trying to change the default db path to a a separate mounted disk. And I changed the group and permissions and I updated the SELinux Contexts. But still I can see that the db is not starting saying permission denied in the log. Here is my log report

But it works when I put the default path in mongo.conf file
Here is the default directory details (/var/lib/mongo)

I am not sure what else need to be done. A help would be greatly appreciated. Thanks.
