CentOS - Sep 2015 - automounter with users home directories on centos 7.

/home is a directory by default on all GNU/Linux hosts.  If you plan to use it
as a mount point then you need to remove the directory and then start autofs
otherwise there will be a conflict.

[root at server2 home]# mount server1:/home/jason /home/jason
[root at server2 home]#
[root at server2 home]# ls /home/jason/
Desktop  Documents  Downloads  Music  mylogfile.txt  Pictures Public  
Templates  Videos
[root at server2 home]# df -h /home/jason/
Filesystem           Size  Used Avail Use% Mounted on
server1:/home/jason  297M   19M  278M   7% /home/jason
[root at server2 home]#

so it works manually, just not with the automounter.

Correct nfs is working and there aren't any firewall issues.

The problem is probably related to the way and steps that automountd 
takes to perform the mount, which is probably related to the fact that 
/home exists.
The quickest way to figure that out is to mv /home to /home- and then 
try automountd again.  When and autofs file system is access automountd 
will check that the mount point exists and create it if not and then 
perform the mount.

In all this you might have to restart autofs on the client.

Of course, because a manual mount expects a directory to already exist to mount
on. Automounter creates virtual mount points on demand and so if there are
existing directories already in place it will fail.

Stop autofs.  Move the /home out of the way.  Start automounter and than do an
ls /home.  It should "just work"
