I fear that there is no other way to achieve what you want. The problem is that the disk driver/file system level is simply not designed to allow for simultaneous access. You have to either have an application software on top (like a DB, which will coordinate parallel read/write processes to a common data set) or a specialized driver/protocol - like NFS. Either way you have only
one system being responsible for data being read and written (on the FS level), not two.
I hope this helps (understanding, sadly, not solving the problem).

NAME
cmsync - Synchronize files or directories on multiple Serviceguard nodes.
SYNOPSIS
cmsync [-rv] [[-n node_name]...] [src_node:]src_file [...]
DESCRIPTION
cmsync copies files and/or directories to multiple Serviceguard nodes.
cmsync is limited in several ways. cmsync is best suited for situations where other remote copy facilities are not available. For a more
full featured tool for copying files between Serviceguard nodes, see ccp(1m) provided by Distributed Systems Administration Utilities.
To use this command, the local user must have the root access role on each of the involved nodes. For more information on Serviceguard
access control policies, see the manual, Managing Serviceguard.
To use the cmsync command without specifying -n options, the local node must be configured into a Serviceguard cluster. If no -n options
are specified, the files will be copied to all available nodes in the cluster.
Paths may be relative to the current working directory or specified absolutely. Copies between two remote hosts are permitted.
If a file or directory already exists on a destination node, the destination node's copy will be overwritten with no prompting.
The cmsync command is not suited for large files or large numbers of files and may result in a heavy load on the command and Serviceguard
daemons. Other tools such as ccp should be considered for these purposes.
Options And Arguments
-r Recursively copy entire directories.
-v Verbose output will be displayed.
-n node_name
Serviceguard node to copy file to. If no -n options are specified, default is to copy to all nodes within the configured clus-
ter.
src_node
Serviceguard node to retrieve the file from. Defaults to the local node.
src_file
Path to source file on src_node.
RETURN VALUE
cmsync returns the following values:
0 Successful completion.
1 Command failed.
EXAMPLES
Copy the local file /etc/hosts to remote nodes node1 and node2
cmsync -n node1 -n node2 /etc/hosts
Distribute the remote file /etc/passwd to all nodes in the cluster.
cmsync node1:/etc/passwd
