Now, Let us distinguish between first install in any setup and future installs/re-installs Now the first install part. This is the long way. at least. full install preferred. once and highly recommended -- helps later in troubleshooting network scenario quickly through the first machine. Let us call this Machine FirstFullCentos for this example. Now one needs an existing server -- say like FirstFullCentos to carry out further installs.

Couldn't locate the output of your mount command on 10.14.10.15. what can say, anyways HTH, Regards, Rajagopal
