Explanation

To register a PostgreSQL database server VM with a database on NDB, the database data and log files must be located on a separate mount point from the operating system and the binary This is because NDB uses the mount point as the identifier for the database server VM and the database. If the data and log files are on the same mount point as the operating system or the binary installation, NDB will not be able to recognize them as a valid database server VM or database. Therefore, the administrator should create a separate mount point for the data and log files and specify it during the registration process.
