This won't be possible with your current OS. You have to have some kind of locking mechanism in place to regulate disk access.
You could look into solutions that use cluster aware filesystems like Red Hat's GFS (Global File System). This example is obviously part of Red Hat Enterprise Linux, so you'd have to change your OS.
That is the main issue, no clustering software is being used.
Normally we use Microsoft Clustering for any shared SAN volumes.
In this case, we are unable to.
We already have the SAN volume shared via a UNC share on server B.
However, ultimately, the SAN throughput is limited to the copper NIC on Server A.
This is why I was thinking of running a Fiber Crossover cable or GigE crossover cable to copy files back and forth between servers for higher throughput.
Although, the Crossover cable idea may not work as both servers are on a LAN network and you need a Private Network for Crossover cable to communicate.
Does anyone know how you can enable file copy over the Private Crossover cable network explicitly?
If you want a faster server-to-server connection, you could look into getting 2 10Gbit NICs (copper or SFP+) and use a different subnet on there so you can point to the share by it's IP. This way you have a 10Gbit share-pipe from one server to the other server, but you don't have to worry about corrupting data due to sharing virtual disks without clustering.

Thanks, Dev Mgr! Yes, changing OS will not be possible in the current configuration. Hoping the Fiber or 100GE Cross-over method works.

Thanks, Dev Mgr!
We tried to implement the crossover cable method but realized we needed to order a line card and a seperate nic for the private network, per server.
This not only was time consuming but won't work since there is only one slot left on these servers.
Pushing to get Jboss clustering setup soon.
