Mounting a File System Using Mirrormounts
If a file system is mounted on an NFSv4 client using manual mounts or autofs, any additional file systems added to the mounted file system, may be mounted on the client using the mirrormount facility. The client requests access to the new file system using the same mount options as were used on the parent directory. If the mount fails for any reason, the normal NFSv4 security negotiations occur between the server and the client to adjust the mount options so that the mount request succeeds.
Where there is an existing automount trigger point setup for a particular server file system, the automount trigger takes precedence over mirrormounting, so a mirrormount will not occur for that file system. To use mirrormounts in this case, the automount entry would need to be removed.
