Attn: RC Team - Please update your Doc (below) when you have a chance…
It took me about a week to figure this out because your Doc below has a misleading info. I tried to install RC on CentOS at least 3 times, and each time I was getting same issues starting & stopping Mongo. The problem had nothing to do with RC, but mongDB itself. The Mongo engine { mmapv1 } you suggested on your installation Doc below is no longer supported with mongo v4.2 and onward..

Please note, after I changed Mongo engine in /etc/mongod.conf file from mmapv1 to WiredTiger, I was able to start Mongo with no issues…
Please update your Doc. Thank you.
