Acfs is Supported,Installed and Loaded,yet you get "ORA-15477: cannot communicate with the volume driver"
Due to some external factors directory structure for acfs is missing for eg : /dev/asm/
ls -latr /dev/asm/
ls: /dev/asm/: No such file or directory
Due to security you will be having default object creation umask is 077, For Oracle user it is forced to value 022 but ROOT.SH does things under root user which automatically mean that objects (libraries/drivers/etc) are with incorrect privileges therefor not usable by any other user other than "root" itself.
