Root.sh || Error ORA-15238: ORA-15238: ORA-15477: || CLSRSC-258: Failed to configure and start ASM

RHEL 7.6 Oracle grid 12.2.0.1

I was getting this below error when I have to run the root.sh script from the first node, error below when performing installation.

I got the wondering solution after more R&D, now I am sharing solution for helping this post to the DBA community . 

 Error :

ORA-15018: diskgroup cannot be created

Died at /u01/sw/grid/crs/install/crsinstall.pm line 2091.

Solution :

before run the "/u01/sw/grid/root.sh" script we need to uninstall  "/u01/sw/grid/root.sh" 

[root@node1 lib]#

[root@node1 lib]# /u01/sw/grid/bin/acfsroot uninstall

ACFS-9312: Existing ADVM/ACFS installation detected.

ACFS-9314: Removing previous ADVM/ACFS installation.

ACFS-9315: Previous ADVM/ACFS components successfully removed.

[root@node1 lib]#

[root@node1 lib]# /u01/sw/grid/root.sh  << run this script firstly from the first node than run from second node
