Full Stack DR verifies if each file system export has exactly one NFS client option with the source IP address set as 0.0.0.0/0. Full Stack DR only copies this option when creating a new file system on the standby region.

This allows Full Stack DR to mount the file system on any new IP address of the compute instance.

Ensure that each file system export has only one source NFS client export option. Specifically, you should have only one 0.0.0.0/0 as a source of NFS client export options for each export in the file system. This helps you to mount the file system on the standby region.
