The Oracle ACFS registry resource is supported only for Oracle Grid Infrastructure cluster configurations; it is not supported for Oracle Restart configurations. See "Oracle ACFS and Oracle Restart".
With Oracle ASM 12c Release 1 (12.1), the Oracle ACFS registry uses the standard single file system resource available through the SRVCTL file system interface. For more information, refer to "Oracle ACFS File System Resource Management". Using SRVCTL enables applications to depend on registered file systems, such as for management of the registered file systems using srvctl filesystem. By default, acfsutil registry shows only file systems that are set to be always mounted, with the AUTO_START attribute set to always.
The Oracle ACFS registry requires root privileges to register and delete file systems, however, other users can be entitled to start and stop (mount and unmount) the file systems by use of the user option.
