1)
first of all;
For building a Shared APPL_TOP, you could export a local filesystem from your App VM node 1 to node 2 and mount it from node2 using NFS.
That is you could give a vdisk to App VM node 1 and export it to Apps Node 2 using NFS.
It is explained Doc ID 1375769.1 with all its details.
On the other hand, what you are trying to do is something different. You want to export an ACFS from ODA nodes to App VM Node 1 and Node 2 at the same time.
I think you are not an Apps DBA and that's why you are only dealing with the Shared disk and NFS part.
So, your Apps DBA told you to give him a shared disk and you are trying to implement his/or her wish.
Well.
I think it is going to work, because it is documented in "Oracle Database Appliance Kit for WebLogic Server"
("
http://docs.oracle.com/cd/E56825_01/doc.121/e56823.pdf") --> section: Configuring a Common NFS Mount Point to be Shared Across all Coherence VMs
While this note is not for EBS, there is something important written in 1375769.1.
"When entering the location of the install directories for the application tier install, you can either enter the location of a local drive on the machine, or an NFS location that is accessible from the primary application tier node. The recommendation is to install the application tier file system on to a remote file system that can be mounted across various application tier nodes."
Moreoever what is written there is -> "The recommendation is to install the application tier file system on to a remote file system that can be mounted across various application tier nodes."
So there is nothing wrong with your approach.
nfslock should be on in your ODA Base nodes..
Check it using chkconfig..
For shared appl_Top (using NFS), read the document named “Sharing the Application Tier File System in Oracle E-Business Suite Release 12.2” (Doc ID 1375769.1).
There are some recommended NFS parameters and you will find them in section : 4.1 Export the Required Application Tier File System From the Primary Node
2)
About fstab boot automount problem..
There is an easy workaround: you can write the mount command to /etc/rc.d/rc.local.
However, it is better to solve your problem .
your App vms which should have auto mount the nfs shares during boot; are Linux ,right?
I need to see your mount options and enabled services to support those..
so in order to have the required info, please send me the following outputs;
-cat /etc/fstab
-mount -a
-chkconfig --list
-/var/log/messages
-runlevel
-cat /etc/rc.conf
